Error message
Fatal error: Uncaught Error: Call to undefined function mysql_connect()
What broke
The code attempted to use the mysql_connect function, which is part of the deprecated MySQL extension in PHP. This function is no longer available in PHP versions 7.0 and above.
Why it broke
The MySQL extension was removed in PHP 7.0 in favor of the MySQLi and PDO_MySQL extensions. If your code relies on mysql_connect, it will fail to execute in newer PHP environments.
How to fix
To fix this error, you should replace mysql_connect with mysqli_connect or use PDO for database connections. Update your code to use the newer MySQLi or PDO methods for better security and functionality.
