PHP search for Key in multidimensional array

Question

I have this:

Array
(
    [carx] => Array
        (
            [no] => 63

        )

    [cary] => Array
           (
           [no] => 64

            


        

Answer 1

So you don't you your id key for the first level, so loop through and when you find a match stop looping and break out of the foreach

$id = 0;
$needle = 63;
foreach($array as $i => $v)
{
    if ($v['no'] == $needle)
    {
        $id = $i;
        break 1;
    }
}
// do what like with any other nested parts now
print_r($array[$id]);

Then you could use that key to get the whole nested array.
