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

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

give this a shot
<?php
function findIndexof($ar, $str) {
foreach($ar AS $k => $v) {
if ( is_array($v) ) {
$val = findIndexof($v, $str);
if( $val !== false ) {
return $val;
}
} elseif ( strtolower($v) == strtolower($str) ) {
return $k;
}
}
return FALSE;
}
$c[1][] = "Vietnam";
$c[1][] = "China";
$c[1][] = "Thailand";
$c[1][] = "England";
$c[2][] = "USA";
$c[2][] = "Japan";
echo findIndexof($c, 'Vietnam');
?>
You should be able to search arrays of any depth
Hope this woks for you.

Or, a lot easier:
foreach($c as $key=>$row) {
if(false !== array_search("England",$row)) {
echo $key;
}
}
