How can MySQL logging be utilized to track changes made by an (S)FTP server and trigger actions in PHP based on those changes?

To track changes made by an (S)FTP server and trigger actions in PHP based on those changes, you can utilize MySQL logging to keep a record of the file modifications. You can create a trigger in MySQL that fires whenever a new entry is added to the log table, and then have a PHP script that listens for these triggers and performs the necessary actions based on the logged changes.

<?php
// Connect to MySQL database
$mysqli = new mysqli("localhost", "username", "password", "database");

// Check for any triggers in the log table
$result = $mysqli->query("SELECT * FROM log_table WHERE action = 'modify'");

// Perform actions based on the logged changes
while ($row = $result->fetch_assoc()) {
    // Perform actions based on the logged changes
    // For example, you can send an email notification or update a specific file
}

// Close the database connection
$mysqli->close();
?>
