Note Submitter: greg at serberus dot co dot uk ---- With in_array() you need to specify the exact value held in an array element for a successful match. I needed a function where I could see if only part of an array element matched so I wrote this function to do it, it also searches keys of the array if required (only useful for associative arrays). This function is for use with strings: function inarray($needle, $array, $searchKey = false) { if ($searchKey) { foreach ($array as $key => $value) if (stristr($key, $needle)) { return true; } } } else { foreach ($array as $value) if (stristr($value, $needle)) { return true; } } } return false; }
