Как изменить название файла php

<?php

rename

("/folder/file.ext", "newfile.ext");?>

That doesn't rename the file within the folder, as you might assume, instead, it moves the file to whatever the PHP working directory is... Chances are you'll not find it in your FTP tree. Instead, use the following:

<?php

rename

("/folder/file.ext", "/folder/newfile.ext");?>

"Warnings may be generated if the destination filesystem doesn't permit chown() or chmod() system calls to be made on files — for example, if the destination filesystem is a FAT filesystem."

More explicitly, rename() may still return (bool) true, despite the warnings that result from the underlying calls to chown() or chmod(). This behavior can be misleading absent a deeper understanding of the underlying mechanics. To rename across filesystems, PHP "fakes it" by calling copy(), unlink(), chown(), and chmod() (not necessarily in that order). See PHP bug #50676 for more information.

On UNIX-like operating systems, filesystems may be mounted with an explicit uid and/or gid (for example, with mount options "uid=someuser,gid=somegroup"). Attempting to call rename() with such a destination filesystem will cause an "Operation not permitted" warning, even though the file is indeed renamed and rename() returns (bool) true.

This is not a bug. Either handle the warning as is appropriate to your use-case, or call copy() and then unlink(), which will avoid the doomed calls to chown() and chmod(), thereby eliminating the warning.

Just copy the old contents (if necessary), and write the new contents into a new file, then rename over the original file.

Any processes reading from the file will continue to do so, any processes trying to open the file while you're writing to it will get the old file (because you'll be writing to a temp file), and there is no "intermediate" time between there being a file, and there not being a file (or there being half a file).

Oh, and this only works if you have the temp file and the destination file on the same filesystem (eg. partition/hard-disk).

You will get two warnings:
"PHP Warning:  rename(): The first argument to copy() function cannot be a directory in <whatever> on line <whatever>"
"PHP Warning:  rename(t2,/var/run/test/t2): Invalid cross-device link in <whatever> on line <whatever>"

The copy() mentioned I assume is C's copy() and not PHP's copy() function. There is an associated bug in the Ubuntu bug system for this as well, that was escalated to bugs.php.net:
https://bugs.php.net/bug.php?id=54097

The only workarounds right now I believe is using PHP copy($source, $dest) and then on success, PHP unlink($source), or doing system("mv $source $dest") which is hokey, and should be surrounded by quotes for paths with spaces or other shell metacharacters, and possibly escaped for security.

I have tested rename($oldName, $targetName) in PHP 5.3.0 and PHP 5.2.9 on both OS and find that if a file named $targetName does exist before, it will be overwritten with the content of $oldName

<?php
rename('/foo/bar','/foo/bar');
?>

It returns true. It's not documented.

<?php
$fp = fopen ("./dir/ex.txt" , "r+");
$text = fread($fp, filesize("../dir/ex.txt"));
ftruncate($fp, 0);
$text2 = "some value";
fwrite ($fp,  $text2 );
fflush($fp);
fclose ($fp);
if (is_resource($fp))
    fclose($fp);
rename ("./dir", ".dir2"); // will give a «permission denied» error
?>

Strangely it seem that the rename command is  executed BEFORE the handle closing on Windows.

Inserting a sleep() command before the renaming cures the problem.

<?php
$fp = fopen ("./dir/ex.txt" , "r+");
$text = fread($fp, filesize("../dir/ex.txt"));
ftruncate($fp, 0);
$text2 = "some value";
fwrite ($fp,  $text2 );
fflush($fp);
fclose ($fp);
if (is_resource($fp))
    fclose($fp);
sleep(1);    // this does the trick
rename ("./dir", ".dir2"); //no error
?>

However, copy() is, unlike rename(), NOT useable for "atomic updates". Another process may actually access the destination file while copy() is working. In such a case, the other process with perceive the file as empty or with incomplete content ("half written").

Probably rename($old, $new) with an existing new was caused by permission problems.  I bet the other problems you had were the result of not calling clearstatcache(), which can cause PHP to act like a file exists though it has since been deleted.

rename("/tmp/somefile.tar", "/mnt/laptop storage/somefile.tar");

If you use the backslash, like if you were cd-ing to the directory, rename will fail.  Example:

rename("/tmp/somefile.tar", "/mnt/laptop storage/somefile.tar");

While not really a bug, it did confuse me for a little bit while working on a backup script.

$rem = $_GET['file'];
$ticket = uniqid(rand(), true);

rename("$rem", "www/home/storefile/$ticket$rem");

the output looks like this - 6881432893ad4925a1.70147481filename.txt

This also helps if you want different versions of the file stored.

changeext($directory, $ext1, $ext2, $verbose)

i wrote this function to rename the extention of some files in a folder and sub-folders inside it ..

parameter 1 :  the directory name
parameter 2 :  the first extention wich we want to replace
parameter 3 :  the new extention of files

for a simple usage call the function :
changeext('dir', 'html', 'php',  'false');

to change evry file name with extention html  into php  in the directory  dir

<?phpfunction changeext($directory, $ext1, $ext2, $verbose = false) {
  $num = 0;
  if($curdir = opendir($directory)) {
   while($file = readdir($curdir)) {
     if($file != '.' && $file != '..') {$srcfile = $directory . '/' . $file;
       $string  = "$file";
       $str     = strlen($ext1);
       $str++;
       $newfile = substr($string, 0, -$str);
       $newfile = $newfile.'.'.$ext2;
       $dstfile = $directory . '/' . $newfile;

       if (

eregi(".$ext1",$file)) { # Look at only files with a pre-defined extension
       $fileHand = fopen($srcfile, 'r');
       fclose($fileHand);
       rename($srcfile, $dstfile );
       }

       if(

is_dir($srcfile)) {
         $num += changeext($srcfile, $ext1, $ext2, $verbose);
       }
     }
   }
   closedir($curdir);
  }
  return $num;
}changeext('dir', 'html', 'php',  'false');?>

to remove the extention of files , just leave the parameter $ext2 blank ''

function rename_win($oldfile,$newfile) {
   if (!rename($oldfile,$newfile)) {
      if (copy ($oldfile,$newfile)) {
         unlink($oldfile);
         return TRUE;
      }
      return FALSE;
   }
   return TRUE;
}

e.g.

rename('/home/user/me/dir1', '/mnt/shares/nfsmount/dir2')

will create a file called 'dir2' on the share and not a directory.

This caught me out and my (quickest) solution was to use an exec and mv command:

<?php

$cmd = 'mv "/home/user/me/dir1" "/mnt/shares/nfsmount/dir2"';

exec($cmd, $output, $return_val);

if (

$return_val == 0) {

   echo "success";

} else {

   echo "failed";

}

?>

Tested here with PHP 5.5.9 (x86), in Linux environment (Ubuntu 14.04.5 LTS i686), with source file (60 GB RAR file) in ext4 filesystem and destination is a external HD with NTFS filesystem. Only 4 GB was copied and RAR was corrupted: "Unexpected end of archive".

Not tested if rename() can move files larger than 4 GB in 64-bit environment.

Note that you can pass an SplFileInfo object as either argument:

<?php

# Assume a file 'foo' in the current directory
rename('foo', new SplFileInfo('bar'));
# foo is now bar!
rename(new SplFileInfo('bar'), 'foo');
# bar is now foo again

?>

<?php

$filePath

= 'testFile.txt';
$fileObj = new SplFileObject(  $filePath  );
rename( $filePath, 'newName.txt'  );// You will get - Permission denied error$filePath = 'testFile.txt';
$fileObj = new SplFileObject( 'filePath.txt' );
$fileObj = null;
rename( $filePath, 'newName.txt'  );// and now it is working.
?>

<?php
$path = "my_doc";

function

getDirectory( $path = '.', $level = 0 ){$ignore = array( 'cgi-bin', '.', '..' );$dh = @opendir( $path );

        while(

false !== ( $file = readdir( $dh ) ) )
    {
        if( !in_array( $file, $ignore ) )
        {
            $spaces = str_repeat( '&nbsp;', ( $level * 4 ) );
            if( is_dir( "$path/$file" ) )
            {
                echo "<strong>$spaces $file</strong><br />";
                rename($path."\".$file, strtolower($path."\".$file));
                getDirectory( "$path/$file", ($level+1) );

                            }
            else {
                echo

"$spaces $file<br />";
                rename($path."\".$file, strtolower($path."\".$file));
            }
        }  
    }
    closedir( $dh );
} getDirectory( $path , 0 )?>

Not what I expected.
