mail — Send mail

Description

Parameters

Receiver, or receivers of the mail.

The formatting of this string must comply with » RFC 2822. Some examples are:

• user@example.com
• user@example.com, anotheruser@example.com
• User
• User , Another User

Subject of the email to be sent.

Subject must satisfy » RFC 2047.

Message to be sent.

Each line should be separated with a CRLF (rn). Lines should not be larger than 70 characters.

(Windows only) When PHP is talking to a SMTP server directly, if a full stop is found on the start of a line, it is removed. To counter-act this, replace these occurrences with a double dot.

String or array to be inserted at the end of the email header.

This is typically used to add extra headers (From, Cc, and Bcc). Multiple extra headers should be separated with a CRLF (rn). If outside data are used to compose this header, the data should be sanitized so that no unwanted headers could be injected.

If an array is passed, its keys are the header names and its values are the respective header values.

Before PHP 5.4.42 and 5.5.27, repectively, additional_headers did not have mail header injection protection. Therefore, users must make sure specified headers are safe and contains headers only. i.e. Never start mail body by putting multiple newlines.

When sending mail, the mail must contain a From header. This can be set with the additional_headers parameter, or a default can be set in php.ini .

Failing to do this will result in an error message similar to Warning: mail(): «sendmail_from» not set in php.ini or custom «From:» header missing . The From header sets also Return-Path when sending directly via SMTP (Windows only).

If messages are not received, try using a LF (n) only. Some Unix mail transfer agents (most notably » qmail) replace LF by CRLF automatically (which leads to doubling CR if CRLF is used). This should be a last resort, as it does not comply with » RFC 2822.

The additional_params parameter can be used to pass additional flags as command line options to the program configured to be used when sending mail, as defined by the sendmail_path configuration setting. For example, this can be used to set the envelope sender address when using sendmail with the -f sendmail option.

This parameter is escaped by escapeshellcmd() internally to prevent command execution. escapeshellcmd() prevents command execution, but allows to add additional parameters. For security reasons, it is recommended for the user to sanitize this parameter to avoid adding unwanted parameters to the shell command.

Since escapeshellcmd() is applied automatically, some characters that are allowed as email addresses by internet RFCs cannot be used. mail() can not allow such characters, so in programs where the use of such characters is required, alternative means of sending emails (such as using a framework or a library) is recommended.

The user that the webserver runs as should be added as a trusted user to the sendmail configuration to prevent a ‘X-Warning’ header from being added to the message when the envelope sender (-f) is set using this method. For sendmail users, this file is /etc/mail/trusted-users .

Return Values

Returns true if the mail was successfully accepted for delivery, false otherwise.

It is important to note that just because the mail was accepted for delivery, it does NOT mean the mail will actually reach the intended destination.

Changelog

Examples

Example #1 Sending mail.

Using mail() to send a simple email:

// The message
$message = «Line 1rnLine 2rnLine 3» ;

// In case any of our lines are larger than 70 characters, we should use wordwrap()
$message = wordwrap ( $message , 70 , «rn» );

// Send
mail ( ‘caffeinated@example.com’ , ‘My Subject’ , $message );
?>

Example #2 Sending mail with extra headers.

The addition of basic headers, telling the MUA the From and Reply-To addresses:

= ‘nobody@example.com’ ;
$subject = ‘the subject’ ;
$message = ‘hello’ ;
$headers = ‘From: webmaster@example.com’ . «rn» .
‘Reply-To: webmaster@example.com’ . «rn» .
‘X-Mailer: PHP/’ . phpversion ();

mail ( $to , $subject , $message , $headers );
?>

Example #3 Sending mail with extra headers as array

This example sends the same mail as the example immediately above, but passes the additional headers as array (available as of PHP 7.2.0).

= ‘nobody@example.com’ ;
$subject = ‘the subject’ ;
$message = ‘hello’ ;
$headers = array(
‘From’ => ‘webmaster@example.com’ ,
‘Reply-To’ => ‘webmaster@example.com’ ,
‘X-Mailer’ => ‘PHP/’ . phpversion ()
);

mail ( $to , $subject , $message , $headers );
?>

Example #4 Sending mail with an additional command line parameter.

The additional_params parameter can be used to pass an additional parameter to the program configured to use when sending mail using the sendmail_path .

Example #5 Sending HTML email

It is also possible to send HTML email with mail() .

// Multiple recipients
$to = ‘johny@example.com, sally@example.com’ ; // note the comma

// Subject
$subject = ‘Birthday Reminders for August’ ;

// Message
$message = ‘

Birthday Reminders for August

mail — Отправляет электронную почту

(PHP 4, PHP 5, PHP 7)

mail — Отправляет электронную почту

Описание

Отправляет электронную почту.

Список параметров

Получатель, или получатели письма.

Формат этого параметра должен соответствовать » RFC 2822. Несколько примеров:

• user@example.com
• user@example.com, anotheruser@example.com
• User
• User , Another User

Тема отправляемого письма.

Тема должна соответствовать » RFC 2047.

Каждая строка должна быть отделена символом CRLF (rn). Строки не должны быть длиннее 70 символов.

(Только для Windows) Если PHP передаёт данные напрямую SMTP-серверу и в начале строки стоит точка, то она будет удалена. Чтобы избежать этого замените все такие точки на две.

Строка, которая будет дополнительно вставлена в конец отправляемых заголовков письма.

Обычно используется для добавления дополнительных заголовков (From, Cc, and Bcc). Несколько дополнительных заголовков должны быть разделены CRLF (rn). Если для составления этого заголовка используются внешние данные, то они должны быть проверены для избежания инъекций нежелательных заголовков.

При отправке письмо должно содержать заголовок From. Он может быть установлен с помощью параметра additional_headers , или значение по умолчанию может быть установлено в php.ini .

Если заголовок отсутствует, будет сгенерировано сообщение об ошибке вида Warning: mail(): «sendmail_from» not set in php.ini or custom «From:» header missing. Заголовок From также определяет заголовок Return-Path в Windows.

Если сообщения не отправляются, попробуйте использовать только LF (n). Некоторые агенты пересылки сообщений Unix (особенно » qmail) автоматически заменяют LF на CRLF (что приводит к двойному CR, если использовалось CRLF). Используйте эту меру в крайнем случае, так как это нарушает » RFC 2822.

Параметр additional_parameters может быть использован для передачи дополнительных флагов в виде аргументов командной строки для программы сконфигурированной для отправки писем, указанной директивой sendmail_path. Например, можно установить отправителя письма при использовании sendmail с помощью опции -f.

Параметр автоматически экранируется функцией escapeshellcmd() , чтобы не допустить выполнение команд. Но escapeshellcmd() позволяет добавлять дополнительные параметры. В целях безопасности рекомендуется проверять и очищать этот параметр.

Так как escapeshellcmd() применяется автоматически, то нельзя использовать некоторые символы, допустимые к использованию в email-адресах некоторыми RFC. mail() не допускает такие символы, поэтому в программах, в которых они требуются, рекомендуется использовать альтернативы для их отправки (например фреймворки или библиотеки).

Пользователь, под которым работает веб-сервер должен быть добавлен в список доверенных в конфигурации sendmail для того чтобы избежать добавления заголовка ‘X-Warning’ при указании отправителя с помощью опции (-f). Для пользователей sendmail — это файл /etc/mail/trusted-users .

Возвращаемые значения

Возвращает TRUE , если письмо было принято для передачи, иначе FALSE .

Важно заметить, что то что письмо было принято для передачи вовсе НЕ означает что оно достигло получателя.

Список изменений

Примеры

Пример #1 Отправка письма.

Использование функции mail() для отправки простого письма:

// Сообщение
$message = «Line 1rnLine 2rnLine 3» ;

// На случай если какая-то строка письма длиннее 70 символов мы используем wordwrap()
$message = wordwrap ( $message , 70 , «rn» );

// Отправляем
mail ( ‘caffeinated@example.com’ , ‘My Subject’ , $message );
?>

Пример #2 Отправка письма с дополнительными заголовками.

Добавление простых заголовков, сообщающих почтовому агенту адреса From и Reply-To:

= ‘nobody@example.com’ ;
$subject = ‘the subject’ ;
$message = ‘hello’ ;
$headers = ‘From: webmaster@example.com’ . «rn» .
‘Reply-To: webmaster@example.com’ . «rn» .
‘X-Mailer: PHP/’ . phpversion ();

mail ( $to , $subject , $message , $headers );
?>

Пример #3 Отправка письма с дополнительными аргументами командной строки.

Параметр additional_parameters может быть использован для передачи дополнительных параметров программе, используемой для отправки писем с помощью директивы sendmail_path.

Пример #4 Отправка HTML-сообщения

С помощью функции mail() также можно отправить и HTML-письмо.

// несколько получателей
$to = ‘aidan@example.com’ . ‘, ‘ ; // обратите внимание на запятую
$to .= ‘wez@example.com’ ;

// тема письма
$subject = ‘Birthday Reminders for August’ ;

// текст письма
$message = ‘

-1 is also semantically meaningless as a bit field, and only works in 2s-complement numeric representations. On a 1s-complement system -1 would not set E_ERROR. On a sign-magnitude system -1 would set nothing at all! (see e.g. http://en.wikipedia.org/wiki/Ones%27_complement)

If you want to set all bits,

0 is the correct way to do it.

But setting undefined bits could result in undefined behaviour and that means *absolutely anything* could happen 🙂

A simple and neat way to get the error level from the error code. You can even customize the error level names further.

= [
E_ERROR => «E_ERROR» ,
E_WARNING => «E_WARNING» ,
E_PARSE => «E_PARSE» ,
E_NOTICE => «E_NOTICE» ,
E_CORE_ERROR => «E_CORE_ERROR» ,
E_CORE_WARNING => «E_CORE_WARNING» ,
E_COMPILE_ERROR => «E_COMPILE_ERROR» ,
E_COMPILE_WARNING => «E_COMPILE_WARNING» ,
E_USER_ERROR => «E_USER_ERROR» ,
E_USER_WARNING => «E_USER_WARNING» ,
E_USER_NOTICE => «E_USER_NOTICE» ,
E_STRICT => «E_STRICT» ,
E_RECOVERABLE_ERROR => «E_RECOVERABLE_ERROR» ,
E_DEPRECATED => «E_DEPRECATED» ,
E_USER_DEPRECATED => «E_USER_DEPRECATED» ,
E_ALL => «E_ALL»
];

echo $exceptions [ «1» ];
$code = 256 ;
echo $exceptions [ $code ];
?>

Output:
E_ERROR
E_USER_ERROR

This will need updating when PHP updates the error level names. Otherwise, it works just fine.

An other way to get all PHP errors that are set to be reported. This code will even work, when additional error types are added in future.

= 0 ;
foreach ( array_reverse ( str_split ( decbin ( error_reporting ()))) as $bit ) <
if ( $bit == 1 ) <
echo array_search ( pow ( 2 , $pot ), get_defined_constants ( true )[ ‘Core’ ]). «
n» ;
>
$pot ++;
>
?>

A neat way to have a place in code to control error reporting configuration 🙂

= [
E_ERROR => FALSE ,
E_WARNING => TRUE ,
E_PARSE => TRUE ,
E_NOTICE => TRUE ,
E_CORE_ERROR => FALSE ,
E_CORE_WARNING => FALSE ,
E_COMPILE_ERROR => FALSE ,
E_COMPILE_WARNING => FALSE ,
E_USER_ERROR => TRUE ,
E_USER_WARNING => TRUE ,
E_USER_NOTICE => TRUE ,
E_STRICT => FALSE ,
E_RECOVERABLE_ERROR => TRUE ,
E_DEPRECATED => FALSE ,
E_USER_DEPRECATED => TRUE ,
E_ALL => FALSE ,
];

error_reporting (
array_sum (
array_keys ( $errorsActive , $search = true )
)
);

super simple error code to human readable conversion:

function prettycode($code) <
return $code == 0 ? «FATAL» : array_search($code, get_defined_constants(true)[‘Core’]);
>

Notes posted above limited to current errors level as on 26th Aug 2016, following snippet will work even on introduction of new error level

$errLvl = error_reporting();
for ( $i = 1; $i

As for me, the best way to get error name by int value is that. And it’s works fine for me 😉
( array_slice ( get_defined_constants ( true )[ ‘Core’ ], 1 , 15 , true ))[ $type ];

//the same in readable form
array_flip (
array_slice (
get_defined_constants ( true )[ ‘Core’ ],
1 ,
15 ,
true
)
)[ $type ]

A shorter version of vladvarna’s FriendlyErrorType($type)
function getErrorTypeByValue ( $type ) <
$constants = get_defined_constants ( true );

foreach ( $constants [ ‘Core’ ] as $key => $value ) < // Each Core constant
if ( preg_match ( ‘/^E_/’ , $key ) ) < // Check error constants
if ( $type == $value )
return( » $key = $value » );
>
>
> // getErrorTypeByValue()

echo «[» . getErrorTypeByValue ( 1 ) . «]» . PHP_EOL ;
echo «[» . getErrorTypeByValue ( 0 ) . «]» . PHP_EOL ;
echo «[» . getErrorTypeByValue ( 8 ) . «]» . PHP_EOL ;
?>

Will give
[E_ERROR=1]
[]
[E_NOTICE=8]

My version!
For long list function returns for example «E_ALL without E_DEPRECATED «

function errorLevel()
<
$levels = array(
‘E_ERROR’,
‘E_WARNING’,
‘E_PARSE’,
‘E_NOTICE’,
‘E_CORE_ERROR’,
‘E_CORE_WARNING’,
‘E_COMPILE_ERROR’,
‘E_COMPILE_WARNING’,
‘E_USER_ERROR’,
‘E_USER_WARNING’,
‘E_USER_NOTICE’,
‘E_STRICT’,
‘E_RECOVERABLE_ERROR’,
‘E_DEPRECATED’,
‘E_USER_DEPRECATED’,
‘E_ALL’
);
$excluded = $included = array();
$errLvl = error_reporting();
foreach ($levels as $lvl) <
$val = constant($lvl);
if ($errLvl & $val) <
$included []= $lvl;
> else <
$excluded []= $lvl;
>
>
if (count($excluded) > count($included)) <
echo ‘
Consist: ‘.implode(‘,’, $included);
> else <
echo ‘
Consist: E_ALL without ‘.implode(‘,’, $excluded);
>
>

Well, technically -1 will show all errors which includes any new ones included by PHP. My guess is that E_ALL will always include new error constants so I usually prefer:

( E_ALL | E_STRICT );
?>

Reason being: With a quick glance anyone can tell you what errors are reported. -1 might be a bit more cryptic to newer programmers.

this would give you all the reported exception list of your configuration.

Try this. If I got any error on any file then I got error mail on my email id. Create two files index.php and checkErrorEmail.php and uploaded them to your server. Then load index.php with your browser.

Are you having trouble understanding PHP mail functions and experiencing PHP mail not working? Have you recently swedged to understand how PHP mail works? You’ve come to the right place, as we have demystified most possible problems you could face with non working PHP mail.

Are you a PHP professional, or perhaps a novice who has yet to master the ropes? Irrespective of the circumstance, there is still more to know about any programming language, and there are occasionally materials that will help developers get better. This is one of them!

Our skilled team has gone above and beyond to explain the concept in this topic to assist you in understanding the scope and concept of how PHP mail works, error handling within a PHP mail function, setting it up to work, and sending PHP mail through Gmail. Here we begin our quest to become a better PHP developer.

Your task now is to give it your all and absorb the information you’ve been given.

The PHP mail() function allows users to send emails to users by using a script. This function takes three necessary input arguments that define the recipient’s email address, its subject, and the message to be sent as well as two optional parameters which are the headers and parameters.

Moving on with the PHP mail() function, the general syntax of this function is as follows:

Mail() can have these parameters inside its brackets: mail(to, subject, message, headers, parameters)

MorParameter values and description are in the table below

An example of how to you PHP mail()

Output:

From the above, you can see the PHP mail function is not working.

For PHP mail to work, it requires a delivery server (SMTP) to send out emails. If you’ve ever sent emails from an application or website while it’s in production, you’re aware of the concern that an email may be exposed to the world.

Are you sure that none of the ‘test’ emails was sent to colleagues or, still, customers? Of course, you may set up and manage a test email server for development purposes, but this is a time-consuming task. Furthermore, the time it takes to examine new test emails might significantly impede your development cycle.

To use PHP mail on your localhost, you require an SMTP(Simple Mail Transfer Protocol). The Simple Mail Transfer Protocol (SMTP) is a program that allows senders and receivers to send, receive, and redirect outgoing emails. Email is transmitted from one server to another across the Internet via SMTP whenever a mail is sent. In layman’s terms, an SMTP email is just an email sent through the SMTP server. The application I currently use on an SMTP server on my localhost is called PaperCut.

The reason why PHP mail is not working are listed below:

Some email service providers do not allow external recipients through PHP mail functions when not working with the localhost. Firstly, change the recipient ($to) from the code above to a local recipient. Simply saying, the email address to be sent to would be from the server’s domain.

Follow the steps below to send mail from the localhost XAMPP using Gmail:

1. Open your compiler (Visual Studio Code)
2. Locate file path “C:xamppphp” and open the “php.ini” file
3. Locate [mail function] within the file
4. Change the values for the following,
   • SMTP = smtp.gmail.com
   • smtp_port = 587
   • sendmail_from = “Gmail username goes here”@gmail.com
   • sendmail_path = “”C:xamppsendmailsendmail.exe” -t” – Only needed in a Unix environment
5. Then, locate file path C:xamppsendmail and open the sendmail.ini file
6. Locate [sendmail] within the file
7. Change the values for the following,
   • smtp_server = smtp.gmail.com
   • smtp_port = 587
   • error_logfile = error.log (Some of this code may have been commented out, just remove the; character)
   • debug_logfile = debug.log
   • auth_username = “enter Gmail username here”@gmail.com
   • auth_password= “your Gmail password goes here”

After the setup has been completed, run the code below again:

<?php
$to = ‘johndoe@email.com’;
$subject = ‘Job Offer’;
$message = ‘Would you be interested in working with us?’;
$from = ‘janejoe@email.com’;
//Sending email
if(mail($to, $subject, $message)) {
echo ‘Your mail has been sent successfully.’;
} else{
echo ‘Unable to send email. Please try again.’;
}
?>

Steps in PHP Mail Test

The script below helps test your hosting to check that you can send emails from PHP-enabled websites with a contact form or something requiring you to send emails to users. The script is used in software, including content management systems (CMS) like WordPress, Wix, Joomla, and the likes.

If you have made adjustments (such as enabling SMTP in PHP settings), this is a fast and straightforward method to ensure the emails are correctly sent.

Create a test script (name the script test.php)  with the following code below:

<?php
ini_set(‘Show errors here’), 1);
error_reporting(E_ALL);
//Write your Email Test address here
$from = “testemail@domain.com”;
//Write the email address you are sending the email to
$to = “username@domain.com”;
$subject = “PHP Mail Test”;
$message = “This is a simple test to check if your PHP Mail works”;
//Remember the header parameter is optional
$headers = “From:” . $from;
mail($to, $subject, $message, $headers);
$sent_mail = mail ($to, $subject, $message, $headers);
$error_message = “Mail not sending”;if ($sent_mail) echo ‘Mail sent successfully!’;
else echo $error_message;
?>

Login in to your server, either your shared hosting or Virtual Private Server (VPS) preferably, and execute the code below.

PHP Mail Error Handling – The Right Way

There are different ways errors can be detected while using the PHP mail function. If your mail does not send for any reason, you can try the method below to display where the error is from.

<?php
ini_set(‘Show errors here’), 1);
error_reporting(E_ALL);
//Write your Email Test address here
$from = “testemail@domain.com”;
//Write the email address you are sending the email to
$to = “username@domain.com”;
$subject = “PHP Mail Test”;
$message = “This is a simple test to check if your PHP Mail works”;
//Remember the header parameter is optional
$headers = “From:” . $from;
mail($to, $subject, $message, $headers);
$sent_mail = mail ($to, $subject, $message, $headers);
$error_message = “Mail not sending”;
if ($sent_mail) echo ‘Mail sent successfully!’;
else echo $error_message;
?>

Because the mail above has not been connected to the service, the $error_message is expected to be displayed in the output; let’s see.

Output:

Conclusion

Without hesitation, we have concentrated on all of the strategies, methods, and actions regarding everything you need to know about PHP mail. In grasping how to resolve errors while using the PHP mail function without stress.  To wrap things up, here’s a quick rundown of what we’ve covered here so far:

• PHP mail() function allows users to send emails to users by using a script
• PHP mail requires three (3) parameters before it can work properly. First, ‘to’ (receiver of the mail), then ‘subject’ (the main topic of the mail – This parameter should not have any newline characters), lastly, ‘message’ (The content to be sent.
• Note: Each line should be separated by a line feed-LF (n). Lines should not be more than 70 characters long).
• Some optional parameters may not be required to be added by the user, which are the headers and other parameters.
• PHP mail syntax is mail(to, subject, message, headers, parameters)

We have provided enough information needed to fix errors in PHP mail. PHP mail is essential when working with contact forms on your website, either developed from scratch or through a CMS such as WordPress, Joomla, Magneto, etc.

Have fun programming.
