What are some best practices for using PHP functions like strrpos(), explode(), and DateTime::createFromFormat for link manipulation?

When manipulating links in PHP, it is important to use functions like strrpos(), explode(), and DateTime::createFromFormat effectively to extract and manipulate the necessary information. For example, to extract the file extension from a URL, you can use strrpos() to find the position of the last occurrence of a period, explode() to split the URL by the period, and DateTime::createFromFormat to ensure the URL is in a valid format before proceeding with manipulation. 

$url = "https://www.example.com/image.jpg";
$file_extension = pathinfo($url, PATHINFO_EXTENSION);
echo $file_extension;
