strip lower case characters

[mobilehell]

hi everyone
i was wondering if anyone knows if there is anyway to strip out lower case letters instead of typing "a" => "" "b" => "" etc. all out

eg if i have this line CoDiNgFoRuMs i would want it to show CDNFRM

Take a look at preg_replace() (http://us2.php.net/manual/en/function.preg-replace.php)
As you should be able to match all lowercase letters with [a-z].

hey tnx man, appreciate it

echo preg_replace('/[a-z]/', '', 'CoDiNgFoRuMs');
