PHP recovers array key as a method of number sequence

The example in this paper describes the method of the key of the PHP recovery array as a digital sequence. Share to everyone for your reference. The specific analysis is as follows:

?

1 2 3 4 5 6 7 8 9 10 11 12

function Restore_array ($arr) { if (!is_array ($arr)) {return $arr;} $c = 0; $new = Array (); while (list ($key, $value) = each ($arr)) { if (Is_array ($value)) { $new [$c] = Restore_array ($value); } else {$new [$c] = $value;} $c + +; } return $new; }

Demo Example:

The code is as follows:

Restore_array (Array (' a ' = = 1, ' b ' = + 2)); --Returns Array (0 = 1, 1 = 2)
