I'd like to return the first key value in the following array such that England would return 1 rather than 3 which is the second key value. Any help would be greatly appreciated.

$c[1][]="Vietnam";
$c[1][]="China";
$c[1][]="Thailand";
$c[1][]="England";
$c[2][]="USA";
$c[2][]="Japan";


print_r($c);
// Array ( [1] => Array ( [0] => Vietnam [1] => China [2] => Thailand [3] => England ) [2] => Array ( [0] => USA [1] => Japan ) )

foreach($c as $row)

    echo array_search("England",$row);

// prints 3

Multi-dimensional arrays can be a bit tricky. I've wanted to do something similar to what you're trying to accomplish. I have not tested this, but I think it works:

<?
foreach ($c as $i => $value) {
    foreach ($value as $j => $country) {
        if ($country == "England")
            echo $i;
    }
}
?>

Hope that helps.
