Why am I getting the \"Fatal error: Uncaught Error: Call to undefined function mysql_connect()\" error in PHP 7?

Debugging "Fatal error: Uncaught Error: Call to undefined function mysql_connect()"

In an attempt to establish a connection to a MySQL database, you've encountered the enigmatic error message: "Fatal error: Uncaught Error: Call to undefined function mysql_connect()".

Fear not, as the culprit behind this error lies in the fact that PHP 7 has bid farewell to the mysql_* functions. As a result, if you're running PHP 7 under the hood of XAMPP, these functions are no longer at your disposal.

To overcome this obstacle, you have two equally capable alternatives at your fingertips:

• MySQLi: A more modern and feature-rich extension that seamlessly replaces the mysql_* functions.
• PDO (PHP Data Object): A database abstraction layer that provides a consistent interface for interacting with various databases, including MySQL.

Consider switching to either MySQLi or PDO, and your database connection woes will be a thing of the past.
