What potential issues can arise when using auto-refresh in PHP scripts?

Potential issues that can arise when using auto-refresh in PHP scripts include excessive server load, potential for infinite loops, and user experience issues such as page flickering. To solve these issues, it is important to set a reasonable refresh interval, implement proper error handling to prevent infinite loops, and consider alternative methods such as AJAX for a smoother user experience.

<?php
$refreshInterval = 60; // Set refresh interval to 60 seconds
header("Refresh: $refreshInterval; url=your_script.php");
?>
