So you want something like this: foreach ($tokenArr as $val) { //... current code // bottom of foreach loop if ($errMess !== '') { break; } }

(foreach isn't a function) It'd be easier to show if you posted the rest of the code instead of just a couple lines, but basically, replace the while loop with a foreach loop, and then add into it a little logic for $errMess. If that still doesn't make sense, post what you came up with (as well as the original code) so we can see what happened and not have to guess about it.

You need to give is some information as to what the actual issue is. Otherwise nobody can or will help you. Another good tip is to encase your code into the <> tag so it shows like this: <?php // database.php require_once __DIR__ . '/config.php'; // Ensure this path correctly points to config.php /** * Establish a new database connection. * * @return mysqli The MySQLi database connection object. * @throws Exception if the connection fails. */ function db_connect() { // Use MySQLi to connect to the database $connection = new mysqli(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME); // Check if the connection was successful if ($connection->connect_error) { error_log("Database connection failed: " . $connection->connect_error); die("Database connection failed. Please check the error log for details."); } // Set the character set to UTF-8 for proper handling of characters if (!$connection->set_charset("utf8mb4")) { error_log("Error setting character set utf8mb4: " . $connection->error); } return $connection; } /** * Close an existing database connection. * * @param mysqli|null $connection The connection object to close. * @return void */ function db_disconnect($connection) { if ($connection instanceof mysqli) { $connection->close(); } } // Establish a connection and store it in the variable $db for use later $db = db_connect(); // You can now use $db for your database queries It makes it easier to read. Also, no need for this: if ($connection instanceof mysqli) { $connection->close(); } PHP automatically closes connections. Okay, your turn
