php extension - Startup: Unable to load dynamic library '/usr/lib/php/modules/module.so' -

when run command

this error comes up

php warning: php startup: unable load dynamic library '/usr/lib/php/modules/module.so' - /usr/lib/php/modules/module.so: cannot open shared object file: no such file or directory in unknown on line 0 php 5.3.3 (cli) (built: feb 22 2013 02:37:06)

this cause mcrypt extension.

edit /etc/php.d/mcrypt.ini

and change

; enable mcrypt extension module extension=module.so 

to this

; enable mcrypt extension module extension=mcrypt.so 

edit:

mini

if directory /etc/php.d not exist – seems don`t have php installed or file mcrypt.ini in different location. try work around.
