What best practices should be followed when incorporating external code, such as the Embed Code for a radio playlist, into a PHP website?

When incorporating external code into a PHP website, it is important to ensure the security and functionality of the website. One best practice is to sanitize and validate the external code before executing it to prevent any potential security vulnerabilities. Additionally, it is recommended to encapsulate the external code within a function or class to maintain code organization and reusability. 

<?php

// Sanitize and validate the external code before executing it
$externalCode = htmlspecialchars($_POST['external_code']);

// Encapsulate the external code within a function or class
function displayExternalCode($externalCode) {
    echo $externalCode;
}

// Call the function to display the external code
displayExternalCode($externalCode);

?>
