I'd like to return the first key value in the following array such

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;
}
}
Well, this is fine, if you know that the array will always be two
levels, not one, not three, but two.
If this is the case, then fine.
But, don't you think it would be nice to have a function that will work
no matter what it is passed?
