Inserting an array into a database?

Question

MySQL

When you run the script, the data should be updated in the database, but for some reason not

<?php
include $_SERVER['DOCUMENT_ROOT']."/include/config.php";
$text = '/check c465ea378a4f'; 
preg_match('~/check ([a-z0-9]+)~i', trim($text), $preg); 
print_r($preg);
foreach ($preg as $key => $value) {
$sql = $db->query('UPDATE `orders` SET `chat_id` = 123456 WHERE `orders`.`identify` = "'.$value.'"');	
}
//echo print_r($preg);
//$idet = 1;
