Introduction

PHP memory limit defines the maximum amount of RAM a single script can allocate during execution, and adjusting this limit is essential for resource-intensive operations. Image processing, large dataset manipulation, complex calculations, or memory-intensive plugins may require increased memory allocation to function properly without fatal errors. DirectAdmin’s PHP Settings interface provides a straightforward method for configuring memory limits through custom PHP overrides. This guide explains how to modify memory limit using the PHP Settings section in DirectAdmin, enabling your PHP scripts to access appropriate memory resources for their operations while maintaining server stability.

Prerequisites

Access to DirectAdmin control panel with the necessary permissions.

Step-by-step Guide

Step 1: Access DirectAdmin

Step 2: Access PHP Settings

Go to the Your Account section and click on Domain Setup. Then, select the domain/subdomain you wish to modify PHP settings for by clicking on the domain/subdomain name.

At the PHP Access row, click Php Settings…. You should be able to see a list of your current PHP configuration.

Step 3: Modify Memory Limit

Scroll down to the Add Override section. On the memory_limit row, you may select the maximum amount of memory you wish a PHP script can allocate.

Then, click Save on the right.

Step 4: Verify the changes

You may confirm the new override settings in the updated Domain php.ini overrides table. If increased, PHP scripts can now use more RAM needed for large operations.

Conclusion

Configuring PHP memory limit through DirectAdmin’s PHP Settings interface is a simple process that controls how much RAM individual scripts can allocate. Adjusting this limit enables resource-intensive operations to complete successfully while protecting overall server resources from excessive memory consumption by individual scripts.
