What are the potential consequences of not including the mysql_connect.php file in a PHP script?

Without including the mysql_connect.php file in a PHP script, the script will not be able to establish a connection to the MySQL database, resulting in SQL queries not being executed and data not being retrieved or stored. To solve this issue, you need to include the mysql_connect.php file in your PHP script to establish a connection to the database before executing any SQL queries.

<?php
// Include the mysql_connect.php file to establish a connection to the database
include 'mysql_connect.php';

// Your SQL queries and other database operations can now be executed
// Example: mysqli_query($connection, "SELECT * FROM table_name");

// Remember to close the database connection when done
mysqli_close($connection);
?>
