Regex expression to mach one of many strings in php -

-

i totally new regex , want match if value 1 of following

cs,ch,es,ee,it,me

till have tried 

if (preg_match("/^[cs|ch|es|ee|it|me]{2}$/",$val))     echo "true"; else     echo "false";

its working fine true cases returns true reverse of them sc,hc etc. helpful if refer source/books learn php.

remove character class [] regex , wrap them using (). remove {2} not necessary anymore.

if (preg_match("/^(cs|ch|es|ee|it|me)$/",$val))

and you.
