Are there any best practices for handling URLs in PHP messages?

When handling URLs in PHP messages, it is important to properly encode the URLs to prevent any issues with special characters or malicious input. One common practice is to use the urlencode() function to encode the URLs before including them in the message. 

$url = "https://example.com/page?param=value";
$encoded_url = urlencode($url);
$message = "Click <a href='" . $encoded_url . "'>here</a> to visit the website.";
echo $message;
