How do I match modules?

[balunadig]

I have memcached 1.4.5 and PHP 5.3.2 running on RHEL 5.3. I get the following when I try to use memcahed.

 

PHP Warning:  PHP Startup: memcache: Unable to initialize module

Module compiled with module API=20050922

PHP    compiled with module API=20090626

These options need to match

 

PHP Fatal error:  Class 'Memcache' not found in /var/www/html/...

 

Can someone help me resolve this? How do I find the matching modules? Do I downgrade PHP or upgrade memcahed?  Appreciate any and all help..

 

Regards
