When running the CLI version of PHP from the command line, you may receive errors like the following:

[root@myserver /root]$ php -v

PHP Warning:  Module ‘memcache’ already loaded in Unknown on line 0

PHP 5.2.3 (cli) (built: Jun 14 2007 15:29:17)

Cause

There are two ways to load most extensions in PHP. One is by compiling the extension directly into the PHP binary. The other is by loading a shared extension dynamically via an ini file. The errors indicate that dynamic extensions are being loaded via .ini files, even though they are already compiled into the PHP binary.

Fix:

To fix this problem, you must edit your php.ini (or extensions.ini) file and comment-out the extensions that are already compiled-in. For example, after editing, your ini file may look like the lines below:

;extension=memcache.so

You may also erase this line instead of commenting them out. Once you have disabled those lines save the file and restart apache. 

>>/etc/init.d/httpd restart

Run php -v to see if the warnings go away.

OR 

You may also remove it from special configuration file which creates while installation:

vi /etc/php.d/memcache.ini 

/etc/php.d/memcache.ini 

Configuration file contents

;extension=memcache.so

You may also erase this line instead of commenting them out. Save the file and restart apache.

>>/etc/init.d/httpd restart

Rrun the following command:

php -v 

You will see the warnings go away.
