i've PHP Version: 5.1.2-1 and i want to enable Imap and Mcrypt support.
> but dont know how ?
It depends. If you're using a packaged system (debian, fedora etc etc) - install the modules package (php-imap, php-mcrypt).
If you compiled from source, you'll need to recompile with different switches.
See http://www.php.net/imap and http://www.php.net/mcrypt for instructions.
and secondly > how can i disable memory_limit ???
edit your php.ini file and change it. memory_limit = 0 -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
