How can encoded JavaScript tags be manipulated to bypass security measures in PHP applications?

Encoded JavaScript tags can be manipulated to bypass security measures in PHP applications by using techniques like URL encoding, base64 encoding, or obfuscation to hide malicious code within the JavaScript tags. To prevent this, developers should sanitize and validate user input, use secure coding practices, and implement output encoding to prevent script injection attacks. 

<?php
$user_input = $_POST['user_input'];
$clean_input = htmlspecialchars($user_input, ENT_QUOTES, 'UTF-8');
echo $clean_input;
?>
