What are the potential risks of relying on third-party scripts for website functionality in PHP development?

Relying on third-party scripts for website functionality in PHP development can pose security risks such as vulnerabilities, data breaches, and potential downtime if the third-party service goes down or changes its functionality. To mitigate these risks, it is important to thoroughly vet and review third-party scripts before integrating them into your website, regularly update them to patch any security vulnerabilities, and have contingency plans in place in case the third-party service becomes unavailable. 

// Example of securely integrating a third-party script in PHP

// Check if the third-party script is loaded securely
if (strpos($_SERVER['HTTP_REFERER'], 'https://thirdpartywebsite.com') !== false) {
    include 'third-party-script.php';
} else {
    // Handle the case where the script is not loaded securely
    echo 'Error: Third-party script cannot be loaded.';
}
