Change the PHP configuration (php.ini)

More control with MAMP PRO

In MAMP, PHP settings apply globally to all projects. MAMP PRO lets you configure PHP settings individually per host – useful when different projects require different configurations.

Steps

1. Start MAMP.
2. Stop the servers if they are running.
3. Note which PHP version is currently selected in the main window.
4. Open the php.ini file for that PHP version in a text editor. The file is located at:

   /Applications/MAMP/bin/php/phpX.Y.Z/conf/php.ini

   Replace X.Y.Z with your PHP version number (e.g. php8.3.30).
5. Edit the desired values.
6. Save the file.
7. Start the servers.
