PHP Warning: Module '' already loaded in:

Symptoms

When performing an audit of your error logs, you may find log entries such as

PHP Warning: Module 'imagick' already loaded in Unknown on line 0. 

This warning could be another module, or on another line, however, the error is generally the same.

Description 

This warning is a result of the module having been added more than once, or is in more than one ini file such as zzzzz-pecl as well as the module.ini file. This can occur when the module has been installed through yum and as an additional pecl module.

Workaround

You can use grep to search the /opt/cpanel/ea-phpXX/etc/php.d folder for the module that is being loaded multiple times.

As an example, for imagick, we can recursively grep all of the ea-php version in the root/etc folder.

[13:30:50 server root@server /opt]cPs# grep -Ri imagick /opt/cpanel/ea-php*/root/etc

When checking the individual files, we can see multiple entries for this module.

[13:30:51 server root@server /opt]cPs# cat /opt/cpanel/ea-php56/root/etc/php.d/imagick.ini

Use your favorite editor from the command line such as vi/vim/pico and remove the additional entries in the files previously found. Be sure to use the restart script/scripts/restartsrv_apache_php_fpm if PHP-FPM is in use.
