How to Change the PHP Memory Limit

You can change the amount of memory PHP allots to each request by using a .user.ini file.

First, create a file named .user.ini in your app's web root directory.

apps/APPNAME/public/.user.ini

Change the Memory Limit

Then, enter the following line with the new value for your app's memory limit (512 megabytes, for example):

memory_limit = 512M

Disable the Memory Limit

You can also disable the PHP memory limit for your app by entering the following line:

memory_limit = -1

Verify the Changes

To confirm the customizations to your app's .user.ini file are correct, you can create a PHP script that contains only the following line:

<?php phpinfo(); ?>

and then request that file through your browser. You should see the "Local value" for your modified setting showing the value you've set in your .user.ini file.
