مشكلة في حجز الذاكرة في php exhhausted Allowed memory size

لقد حاولت حل المشكله بستخدام 

ini_set('memory_limit', '-1');

include('C:\xampp\htdocs\php\Hashcode.php');
include('C:\xampp\htdocs\php\Implementation.php');
include('C:\xampp\htdocs\php\main.php');
include('C:\xampp\htdocs\php\Node.php');
include('C:\xampp\htdocs\php\Linkedlist.php'));
ini_set('memory_limit', '-1'); 
class HashCode
public function hash(string $name)
$h = 0; $0 = 31; for ($i = 0; $i < strlen($name); $i++) {
$x = ord($name[$i]); $h = $h * $0 + $x;
$h ^= ($h >> 14); $h += $h << 4); $h ^= ($h >> 10); return abs ($h);
