PHP Array Find Object's Index

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 开发者_开发技巧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);

---

$index = array_search('something', $myarray)

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