Array find value

[slice]

Is it possible to find index of array where values is "any value" ?

Suppose there is array from index 0 to 99 and have same values stored 0 to 99.

And we want to find the index of array where value is "35".

I need some fast solution otherwise it can done thru for loop.

<?php
$array = array(0 => 'blue', 1 => 'red', 2 => 'green', 3 => 'red');

$key = array_search('green', $array); // $key = 2;
$key = array_search('red', $array);  // $key = 1;
?>
