How to solve sublimelinter php syntax not working

When using Sublime Text as a programming tool, we often use plug-ins such as SublimeLinter to help us check the code and prompt for syntax errors to improve the quality and efficiency of the code. However, when using SublimeLinter's PHP syntax check, certain problems may occur, such as the syntax check not working. This article will introduce the solution to this problem.

1. Confirm that SublimeLinter and its plug-in have been installed correctly

First, we need to confirm that the SublimeLinter plug-in and its corresponding PHP syntax checking plug-in have been installed correctly. In Sublime Text, press "Ctrl Shift P" to open the command palette and enter "Package Control: Install Package". In the pop-up menu bar, search for SublimeLinter and its related plug-ins, such as SublimeLinter-php. If it is installed, the menu bar will be gray, otherwise it can be installed. After the installation is complete, we need to restart Sublime Text.

2. Confirm that the PHP executable file path is correct

When performing syntax checking, SublimeLinter needs to know the PHP executable file path, otherwise the syntax check cannot be performed. We can open a PHP file in Sublime Text and check the SublimeLinter prompt information in the status bar to see if the path to the PHP executable file is displayed. If it is not displayed, it means you need to manually configure the PHP path.

In Sublime Text, press the "Ctrl Shift P" key to open the command panel, enter "Preferences: SublimeLinter Settings", find the corresponding PHP syntax check plug-in configuration, such as SublimeLinter-php, and then find "executable_path" parameter, set it to the path to the PHP executable on your system. For example:

"executable_path": "/usr/bin/php"

3. Confirm that the PHP syntax check plug-in is configured correctly

After confirming that the PHP executable file path is correct, we also need to confirm that the PHP syntax check plug-in is configured correctly. When performing PHP syntax checking, SublimeLinter will execute a command similar to the following:

php -l myfile.php

where "myfile.php" is the file we are editing. If our PHP file is in a different directory than the directory where this command is located, we need to set the "working_directory" parameter to the directory where our PHP file is located.

For example, if our PHP file is located in the "/var/www/myproject/" directory, you need to set the following content in the SublimeLinter-php plug-in configuration file:

"working_directory": "/var/www/myproject/"

In addition , we also need to confirm whether the PHP syntax checking plug-in is enabled. In the plug-in configuration file, you need to set the PHP syntax checking plug-in in the "linters" parameter to the "enable" state. For example:

"linters": {
        "php": {
            "disable_if_not_dependency": false,
            "executable": null,
            "error_stream": true,
            "args": [],
            "excludes": [],
            "working_directory": null,
            "enable": true
        }
 }

4. Confirm that PHP syntax check is available

After completing the above steps, we also need to confirm whether PHP syntax check can be used normally. Open a PHP file, deliberately add a syntax error or other error in the file, save the file, SublimeLinter should be able to automatically prompt the problem and mark it with an underline or other color.

If SublimeLinter still does not work properly, we can confirm whether the file is saved correctly, or manually execute the PHP syntax check command in the terminal to confirm whether PHP syntax check is available.

The above is the method to solve the problem that SublimeLinter PHP syntax check does not work. Of course, we may encounter other problems when using SublimeLinter, which requires us to conduct detailed investigation and debugging according to the specific situation. By using plug-ins like SublimeLinter, we can greatly improve the quality and efficiency of our code writing. I hope this article will be helpful to you.
