How to override PHP settings

Override php.ini values such as memory_limit, upload size and execution time per application on TurboStack with a .user.ini file.

You can override most runtime php.ini values - such as memory_limit, max_execution_time and the upload size limits - per application, without root access. To choose the PHP version or tune PHP-FPM, see Configure PHP instead.

Override per application with a .user.ini file

Create a .user.ini file in your application's document root (for example public_html) and add one setting per line:

memory_limit = 512M
max_execution_time = 300
post_max_size = 600M
upload_max_filesize = 512M

Most settings that PHP allows to be changed at the directory level can be overridden this way.

Override for the command line

A .user.ini file applies to web requests only. For a one-off command-line run, pass the value with -d:

php -d memory_limit=512M your-script.php

Application-specific exceptions

Some applications set their own PHP values that take precedence over .user.ini for web requests. Magento, for example, enforces limits through a PHP_VALUE line in its generated 50main.conf (see Custom Nginx configuration):

fastcgi_param PHP_VALUE "memory_limit=2048M \n max_execution_time=18000";

If a .user.ini change has no effect on such a site, look for an override like this first.

Verify

Confirm the value actually applied with a temporary phpinfo() page:

<?php phpinfo();

Open it in your browser, search for the setting, then delete the file - never leave a phpinfo() page on a live site.
