Answer 1

I had the same situation. In my case the problem was that I had two configuration files for memcache in /etc/php5/cli/conf.d/.

php -i | grep memcache.ini

In my case the result was:

/etc/php5/cli/conf.d/20-memcache.ini,
/etc/php5/cli/conf.d/memcache.ini

To get rid of the warning message I removed the line extension=memcache.so from the memcache.ini file.

Answer 2

When you install php5-memcache it adds it's own memcache.ini file which is set to load that extension already. So Just remove/comment the loading of the extension from your php.ini.

 ;extension=memcache.so

Similar with APC (Alternative PHP Cache Module).

 ;extension=apc.so

Answer 3

If you are using php5.4 (CentOS 6.5),

• Goto /etc/php.d/

• in memcache.ini comment the extension

  ;extension=memcache.so
  

• likewise in apc.ini

  ;extension=apc.so

I came here looking for a solution to a similar error i.e. Warning: Module 'pdo_pgsql' already loaded in Unknown on line 0. After looking at various sites, here's the solution I came up with. It worked for me, hope it does for someone with a similar issue.

• Locate the folder conf.d, mine was in the directory /usr/local/etc/php/7.0/conf.d.
• In this folder, there's a file called ext-pdo_pgsql.ini.
• Type sudo nano ext-pdo_pgsql.ini to edit it.
• There should be a line extension="/usr/local/opt/php70-pdo-pgsql/pdo_pgsql.so". Comment it out by adding semi-colon to the beginning of the line i.e. ;extension="/usr/local/opt/php70-pdo-pgsql/pdo_pgsql.so".
• Save the file. (I usually run control + O, control + M).
• Exit the file (control + X).

Answer 5

Its possible that these modules are listed twice and so you get error "Already loaded". Find out which configuration files are loaded

php -i | grep 'Loaded Configuration File'
php -i | grep 'ini'

This will tell you which .ini files are loaded and parsed (Additional .ini files parsed).

Look at the specific files and comment out the second occurrence (as follows)

;extension=memcache.so
;extension=apc.so

Answer 6

there are configuration files modules /etc/php5/mods-available

Open file pdo_mysql.ini and comment line pdo_mysql.so

After service apache2 | php5-fpm restart depending on whether you are using you

Answer 7

I was getting same error,

Module 'sphinx' already loaded

You need to find module (.ini) which is getting loaded more than once and delete one of them,

ubuntu@webserver:~$ grep -R "sphinx" /etc/php5/*

/etc/php5/fpm/conf.d/sphinx.ini:extension=sphinx.so
/etc/php5/fpm/conf.d/20-sphinx.ini:extension=sphinx.so

ubuntu@webserver:~$ sudo rm /etc/php5/fpm/conf.d/sphinx.ini
