How would I figure out where a specific item is in an array? For instance I have an array like this:

("itemone", "someitem", "fortay", "soup")

How would I get the index of "someitem"

Thanks, Christian Stewart

Use array_search()

array_search — Searches the array for a given value and returns the corresponding key if successful

mixed array_search ( mixed $needle , array $haystack [, bool $strict ] )

Example:

$key = array_search('someitem', $array);

You can also use array_keys($array,$search); to return multiple keys (indices) for given value

indices fwiw ;) ... and actually they're keys, since they don't necessarily have to be numbers. – Peter Ajtai Aug 28 '10 at 19:24
