Are there best practices for protecting PHP scripts with sensitive information from web crawlers?

Sensitive information in PHP scripts can be protected from web crawlers by using server-side techniques such as restricting access to the scripts, using encryption for sensitive data, and implementing CAPTCHA to prevent automated access. It's also important to regularly update and secure the server environment to prevent unauthorized access to the scripts. 

<?php
// Example of restricting access to sensitive PHP script
if ($_SERVER["REMOTE_ADDR"] !== "127.0.0.1") {
    header("HTTP/1.0 403 Forbidden");
    exit("Access denied");
}

// Your sensitive PHP code here
?>
