PHP requirements

Testing and debugging features require the PHP program to be installed and configured. It is recommended to use PHP 7.0 or newer; however, PHP 5.4 and newer are supported as well.

Running tests and built-in development server requires php with extensions dom, json, mbstring and xmlwriter. Either install php globally, so the command php will work across the system, or set php.executablePath setting within VSCode's Settings pointing to PHP executable.

Debugging locally requires the Xdebug extension installed and enabled. See Xdebug configuration for more information.


  • PHP 7.0 or newer
  • PHP extensions dom, xsl, mbstring
  • PHP extension xdebug with the following options in your php.ini:
    • xdebug.remote_enable = 1
    • xdebug.remote_autostart = 1
