How to increase the PHP memory limit for phpMyAdmin

Introduction

Some actions in phpMyAdmin require a higher PHP memory limit. You would normally become aware of this type of issue when the following error is recorded in the cPanel error log (/usr/local/cpanel/logs/error_log):

PHP Fatal error: Allowed memory size of ### bytes exhausted

Procedure

Depending on the PHP version being used, the PHP configuration file for phpMyAdmin is found in the following path:

/usr/local/cpanel/3rdparty/php/*/etc/phpmyadmin/php.ini

To increase the memory limit, modify the memory_limit line in the configuration file using your preferred text editor.

; Maximum amount of memory a script may consume (128MB)
; http://php.net/memory-limit
memory_limit = 128M

It is recommended to increase this setting incrementally, for example 256M, 384M, as needed.

After editing the php.ini file, you will need to restart the cPanel service:
