How can developers ensure the security of PHP files when running them in browsers with Zend engine integration?

Developers can ensure the security of PHP files when running them in browsers with Zend engine integration by implementing proper input validation, sanitization, and escaping techniques to prevent common security vulnerabilities such as SQL injection, cross-site scripting (XSS), and remote code execution. Additionally, setting strict file permissions, using secure coding practices, and regularly updating PHP versions can help enhance the overall security of PHP files. 

<?php

// Example of input validation and sanitization
$user_input = $_POST['user_input'];
$clean_input = filter_var($user_input, FILTER_SANITIZE_STRING);

// Example of escaping output to prevent XSS
echo htmlspecialchars($clean_input);

?>
