Return if string is in an array

[The_Wanderer]

Hey I need a simple function to determine if a given string is contained in an array

For Instance:
$findInMe = Array('SOLD OUT', 'ERROR', 'EXPIRED', 'NO DEAL');
$givenString = somethingFromMyDatabase;

If $givenString was found in $findInMe then the function would return true

Anybody know how to do this?

Thanks,
I appreciate it!
