looks like this works. Is there any problem with it that people can see?
$c[1][]="Vietnam";
$c[1][]="China";
$c[1][]="Thailand";
$c[1][]="England";
$c[2][]="USA";
$c[2][]="Japan";
print_r($c);
foreach($c as $key=>$value)
{
if(array_search("England",$value))
{
echo $key;
}
}
thanks,

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.

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
