Troubleshooting common PHP debugging issues

This section provides the list of solutions and workarounds for common problems with Debugging in PhpStorm.

Collecting PhpStorm debugging logs

If your issue is not addressed in this section, contact our support engineers. If asked to provide deployment logs, follow the instructions to collect them.

Collect debugging logs

Select Help | Configure Debug Log in the main menu.

In the Custom Debug Log Configuration dialog that opens, add the following lines depending on the issues you are experiencing:

Issues with PHP debugging: #com.jetbrains.php.debug

Click OK and reproduce the issue.

Locate the log file by selecting Help | Show Log in Explorer (for Windows and Linux) or Help | Show Log in Finder (for macOS).

If necessary, you can locate the log manually:

The most recent log file is named idea.log ; older files names end with a number, that is idea.log.1 , idea.log.2 , and so on. In most cases you need only the most recent one.

Attach the log file(s) to the issue or forum thread.

Collecting Xdebug logs

When using Xdebug, it is possible to make it log its actions.

In the Settings dialog ( Ctrl+Alt+S ), go to PHP .

From the PHP executable list, choose the relevant PHP interpreter and click next to it. In the CLI Interpreters dialog that opens, click the Open in Editor link next to the Configuration file:

file. Close all the dialogs and switch to the tab where the php.ini file is opened.

In the php.ini , enable Xdebug logging by adding the following line:

The log file contains the raw communication between PhpStorm and Xdebug as well as any warnings or errors:

The log file will not automatically roll-over or be truncated and may grow to a vast file size. When logging is no longer needed, it is recommended to disable it.

Making sure Xdebug or Zend Debugger are installed and configured

To debug PHP code with PhpStorm, make sure that you have a debugging engine, either Xdebug or Zend Debugger, installed and configured properly.

These tools cannot be used simultaneously because they block each other. To avoid this problem, you need to update the corresponding sections in the php.ini file as described in Configure Xdebug and Configure Zend Debugger.

To validate the debugging engine configuration, perform the steps described in Validate the Configuration of a Debugging Engine

Startup warnings and errors preventing the debugger from working

When running PHP, it can happen that a startup warning or error is displayed. When this is the case, the debugger may fail to work. PhpStorm will also not be able to recognize the debugger being used.

To verify that no startup warnings or errors are displayed, run the following command:

This will return a message similar to the following:

If any errors or warnings are present on the first lines, it’s recommended to fix them before continuing.

Debugger cannot connect

When the debugger cannot connect or refuses the connection, check the following:

Make sure Xdebug or Zend Debugger are configured to connect to the host and port PhpStorm is running on.

In the Xdebug configuration, make sure xdebug.remote_host and xdebug.remote_port ( xdebug.client_host and xdebug.client_port for Xdebug 3) are correct. Refer to the Xdebug documentation for details.

When using Zend Debugger, make sure the generated PhpStorm bookmarklets or a Browser Debugging Extension is configured to use the correct IP address and port.

When using a remote PHP interpreter, verify the steps outlined in Remote debugging via SSH tunnel.

In the Settings dialog ( Ctrl+Alt+S ), navigate to PHP | Debug and make sure PhpStorm and Xdebug / Zend Debugger are configured with the same port numbers.

In PhpStorm, enable listening to incoming debug connections by either clicking on the toolbar or selecting Run | Start Listening for PHP Debug Connections in the main menu. This will ensure PhpStorm reacts when a debugging session is started and opens the Debug tool window automatically. Before launching the script, make sure that either a breakpoint is set or the Break at first line in PHP scripts option is enabled on the Debug page of the Settings/Preferences dialog Ctrl+Alt+S .

Verify no firewall, router or ISP is blocking the connection. This can be verified by running telnet host 9000 (for Xdebug) or telnet host 10137 (for Zend Debugger) from remote server (where host is an IP address of your local machine running PhpStorm) and checking a connection is established. You can use http://www.canyouseeme.org or a similar service to check for opened inbound ports.

Make sure that xdebug.remote_host (for Xdebug 2), xdebug.client_host (for Xdebug 3), or zend_debugger .allow_hosts (for Zend Debugger) are properly configured. The value can be a host name (for example, localhost ) or an IP address of the machine where PhpStorm is running, and it must be pingable from the server. When using Xdebug, xdebug.remote_connect_back (for Xdebug 2) or xdebug.discover_client_host (for Xdebug 3) can be used for troubleshooting.

No Debug Server is Configured

If you initiate a Zero-configuration debugging session without having configured a Debug server , upon establishing connection PhpStorm displays the Incoming Connection dialog where suggests importing mappings from a server access configuration ( deployment configuration ). If you choose Import mappings from deployment , PhpStorm tries to detect the most suitable deployment configuration, preselects it in the Deployment list, and the Preview area shows the absolute path to the project file, which corresponds to the currently executed script according to the mappings from the selected configuration.

If PhpStorm does not detect a relevant configuration:

Choose the most suitable configuration from the list or click and create a new configuration in the Deployment dialog that opens, whereupon the new configuration is added to the list.

In the Deployment root field, type the absolute path to the server root folder.

You can also select the Manually choose local file or project option, in this case PhpStorm displays the project tree view where you can select a project file and map the currently executed script to it. You can also select and map the entire project.

Path mappings cannot be set for project files or folders that are marked as excluded.

To continue debugging with the imported or manually specified configuration settings, click Accept .

Remote file path is not mapped to any file path in project

In some cases, the debugger can connect, but you get the error messages indicating that no mapping between the remote and project files is defined. This means that PhpStorm cannot determine which local file corresponds to the file being debugged.

To solve this problem, click Click to set up path mappings and providing the necessary path mappings.

Path mappings are used when the paths to the files processed by the server differ from the paths to the files in the PhpStorm project. This happens in the following cases:

The server is remote and the project files are local copies of the originals.

The files processed by the server and the files opened in the IDE are the same, but symlinks are used. Because the debugger resolves symlinks during a debugging session, you need to tell the IDE actual solute physical paths to the files on the server.

To configure path mappings, in the Settings dialog ( Ctrl+Alt+S ), navigate to PHP | Servers .

If the files that the server processes are in the project and you are not using symlinks, clear the Use path mappings checkbox. In this case, the IDE will open files according to the paths received from the debugger.

A path mapping specified for a parent directory is automatically applied to all its subdirectories. If necessary, path mappings for any subdirectory or file can be specified.

Path mappings cannot be set for project files or folders that are marked as excluded.

Breakpoints are not being hit

When breakpoints are not being hit but the debugger seems to connect, verify the following:

Verify the breakpoint is not disabled. Using the Run | View Breakpoints menu command Ctrl+Shift+F8 , check that breakpoints are enabled. Select the checkbox next to a breakpoint to enable it.

On macOS, when a file or folder is renamed using Finder, and the letter case is changed, PhpStorm may not be able to find the files. If renaming is required, make sure to do it in the IDE or using a terminal and the mv command. Renaming project files or folders using Finder may result in strange behaviour. See here for more details.

There are some rare cases when breakpoints can’t be hit due to technical limitations, for example caused by the way how PHP generates bytecode. See here for more details.

When using Xdebug, you can use the xdebug_break() function to force a breakpoint from within PHP. When Xdebug encounters this function during execution, it will pause at the next statement in the IDE even if no breakpoint was defined there originally.

Xdebug ignores a breakpoint and stops at a line where no breakpoint is defined

This can happen due to the Xdebug’s internal breakpoints resolving mechanism. Under this mechanism, the debugger evaluates whether PHP can generate internal executable bytecode for the current line. If no such code is generated for a line, the corresponding breakpoint cannot be hit. Xdebug will scan up to 5 subsequent lines, and stop at the line where executable code is located. Resolving breakpoints is supported in Xdebug 2.8 and later.

If necessary, you can configure breakpoints resolving support in PhpStorm on the PHP | Debug page of the Settings dialog ( Ctrl+Alt+S ):

In the Xdebug area, use the Resolve breakpoint if it’s not available on the current line (Xdebug 2.8+) checkbox to toggle breakpoint resolving. Note that if resolving is disabled, the breakpoints set on the code lines without executable code will always be ignored.

In the Advanced settings area, use the Notify if breakpoint was resolved to a different line (Xdebug 2.8+) checkbox to choose whether PhpStorm should display a notification message when a breakpoint is resolved.

To get an in-depth technical overview of how breakpoints resolving works, refer to this article and DBGP documentation.

A script is not suspended

Establishing a Zero-Configuration debugging session may fail with no breakpoints hit and therefore the script not suspended. This may happen if the path mappings are not configured or configured erroneously, or if you have not set any breakpoints. In the latter case, you can do any of the following:

Set a breakpoint by clicking the gutter at the desired executable line of code. See Breakpoints for details.

In the Settings dialog ( Ctrl+Alt+S ), go to PHP | Debug and in the External Connections area, select the Break at first line in PHP scripts checkbox.

Enable the Run | Break at first line in PHP scripts option from the main menu.

To have PhpStorm display a notification if the script is not suspended, select the Notify if debug session was finished without being paused checkbox in the Advanced Settings area on the PHP | Debug page of the Settings dialog.

The debugger does not work when using nginx

When using the nginx web server, debugging may fail if the $_SERVER[«SERVER_NAME»] is not provided by PHP. To solve this, add a fastcgi parameter to the nginx configuration:

Refer to the nginx documentation and see here for additional details.

Xdebug cannot connect to PhpStorm

If you see the following messages in Xdebug log:

This means that Xdebug tries to connect to the host and can’t make the connection. To fix the issue, set xdebug.remote_connect_back=0 ( xdebug.discover_client_host=false for Xdebug 3) and make sure that xdebug.remote_host ( xdebug.client_host for Xdebug 3) is set correctly.

Trying to debug a framework CLI command results in PHP errors

When trying to debug a CLI command of a PHP framework command-line tool, such as Symfony Console or Laravel Artisan , debugging fails with a PHP error Fatal error: Class ‘. Command’ not found» or similar.

The common cause for such errors is attempting to debug the file or class with the command directly. Instead, you should use a PHP Script, in which you provide the path to the command-line tool and the actual command to run. In this case, the framework commands bootstrapping logic will apply, and debugging will proceed normally.

Refer to the following framework-specific guides for details:

Zend Debugger will not perform dropping of privileges

When using Zend Debugger on Linux, you may occasionally see the following error:

This error occurs when the debugger cannot determine the UID of the user running the web server process. Find the UID of that user and add it to php.ini :

After updating the setting, restart the web server.

Debugging with ionCube installed

In some PHP environments, ionCube is used to load and run the encoded PHP code. The ionCube loader extension does this by decoding the PHP code that is to be run and then making sure the PHP interpreter can execute it.

Officially, neither Xdebug nor Zend Debugger support running with ionCube enabled, however there are some workarounds to try. Note that these are not supported by JetBrains, ionCube, Xdebug or Zend Debugger.

Make sure the ionCube loader module is loaded first

In php.ini , verify the ionCube loader is loaded before any debugger extension is loaded, for example:

Use ionCube on-demand loading

We can disable the ionCube extension in php.ini and make use of ionCube’s on-demand loading feature. When the first encoded PHP script is loaded, the PHP interpreter will check the configured extenson_dir to find the ionCube extension and run the encoded PHP script.

Note that this method is not officially supported. It should only be used for debugging purposes and never on a production server.
