Extracting the keyname from arrays! How?

[Anon]

I got a problem.. I am trying to compare a variable to the elements of in a subarray in a multidimensional array. If there is a match I want to print the keyname of that array. How?

Example:

$fake_array = array(
'first' => array(1,2,3),
'second' => array(4,5,6),
'third' => array(7,8,9)
);

i do a

$num = 1;
foreach($fake_array as $value) {

        if (in_array($num, $value)) 

and I want to find it in the 'first' subarray so I want to print the word name of the key: first. How do I extract that info?

Thanks!

$num = 1;
foreach($fakearray as $key => $valarr)
{
if(in_array($num,$valarr)
{
print($key);
break;
}
}
