Does anyone know of a PHP function that searches a string?
i am working on a project that needs to search an input string and give different results based on the search.
in the book that i learned php from there is no listing of anything that can search. any help is appreciated

There are several you might use, depending on your specific need.

Here are a few:

strpos()
stripos()
ereg()
eregi()
strstr()
