What are the requirements for running a PHP cron job on a server that supports MySQL and PHP?

To run a PHP cron job on a server that supports MySQL and PHP, you will need to create a PHP script that performs the desired task, such as updating a database or sending emails, and then schedule the script to run at specified intervals using a cron job. Make sure the server has PHP and MySQL installed and that the script has the necessary permissions to run.

<?php
// Your PHP script here

// Example of updating a MySQL database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Perform SQL queries here

// Close connection
$conn->close();
?>
