What are the potential pitfalls of using alerts in PHP scripts?

Potential pitfalls of using alerts in PHP scripts include disrupting the flow of the script and potentially causing confusion for users. To avoid these issues, it is recommended to use PHP functions like echo or print to display messages to users in a more controlled manner.

<?php
// Instead of using alerts, use echo or print to display messages
$message = "Hello, World!";
echo $message;
?>
