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

Question

I am using cPanel for Laravel project. And also quickbook too. But I got the error " PHP Warning: Module 'memcached' already loaded in Unknown on line 0 " when run the command php artisan quickbooks:run . As in other answers I check the php.ini file with WHM to comment that line but there is no such line. But in terminal when I run php --ini the output is:

[usesrs@CentOS etc]$ php --ini

[usesrs@CentOS etc]$

How can I solve this problem?

Answer 1

You should check the contents of

/opt/cpanel/ea-php71/root/etc/php.d/memcache.ini,
/opt/cpanel/ea-php71/root/etc/php.d/memcached.ini,

and probably remove one of them - or put comments (the # sign) at the beginning of the lines.

Answer 2

I got same error for redis which says

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

So in that case I found the redis.ini file on the location

/etc/php/7.4/cli/conf.d/redis.ini

Simply delete that redis.ini file

In your case you also find for same file & try to delete or hide that file.

Thank You!
