I think i've discovered a problem with array_search. If I have an array, say

$arr = Array("one","two","a");

then I try

$retVal = array_search("one",$arr);

it will return false, however the other two elements are fine.

It seems array_search just ignores the first element in the array, I can search the rest of the array fine, just not the first element. If I put another item at the start I can find "one" fine.

in_array works fine, it's just array_search that fails
