Return PHP array name
You can use a foreach statement to get the key value pair of the array:
$outer_arr = array('kanye' => array('Kanya', 'Janaye', 'Kayne', 'Kane'));
foreach($outer_arr as $key => $val) {
print($key); // "kanye"
print_r($val); // Array ( [0] => Kanya [1] => Janaye [2] => Kayne [3] => Kane )
}
If you just need to get the keys, you can use array_keys
$myArray = array(
"Kanye" => array("Kane", ...)
"West" => array("Wst", ...)
);
print_r(array_keys($myArray));
/*
array (
0 => Kanye
1 => West
)
*/
