Disabling XDebug to Enhance Performance

If you suspect that XDebug may be slowing down your server, disabling it can help you test this hypothesis. Here's a comprehensive guide to disabling XDebug:

Modifying php.ini

• Locate your php.ini file and search for the XDebug section.

• Set xdebug.remote_autostart to false:

  • xdebug.remote_autostart=0

• Set xdebug.remote_enable to false:

  • xdebug.remote_enable=0

• Disable your profiler:

  • xdebug.profiler_enable=0

Disabling Extension Loading

• If XDebug is still impacting performance even after disabling certain features, you may need to disable extension loading.

• Locate the entry in your php.ini that looks like:

  • zend_extension = "/path/to/php_xdebug.dll"

• Add a semicolon to comment it out:

  • ;zend_extension = …
