I don't think there's such a function built-in into PHP;
but you can build your own ...

<?php
function array_function($needle, $array) {
$n = 0;
foreach ($array as $value) {
if ($needle == $value) return $n;
++$n;
}
}

$data = array('name'=>'forty-two', 'dob'=>'2006-10-21', 'eye-color'=>'brown');
$zero_index = (int)array_function('brown', $data);

### if ($zero_index != 2) {
### // error!
### }
?>

What you would use it for is beyond my imagination :)
