What are some alternative methods to create clickable links in a PHP signature?

One alternative method to create clickable links in a PHP signature is to use the `preg_replace` function to search for URLs and replace them with anchor tags. This allows you to dynamically convert plain text URLs into clickable links in your signature. 

// Sample PHP code snippet to create clickable links in a signature
function createClickableLinks($text) {
    // Search for URLs in the text and replace them with anchor tags
    $text = preg_replace('/(http[s]?:\/\/[^\s]+)/', '<a href="$1" target="_blank">$1</a>', $text);
    
    return $text;
}

// Example usage
$signature = "Check out my website at https://www.example.com";
echo createClickableLinks($signature);
