Answer 1

Create an array:

$remove = array("http://","https://");

and replace with empty string:

str_replace($remove,"",$url);

it would look something like this:

function removeProtocol($url){
    $remove = array("http://","https://");
    return str_replace($remove,"",$url);
}

Str_replace will return a string if your haystack (input) is a string and you replace your needle(s) in the array with a string. It's nice so you can avoid all the extra looping.

Happy Coding!
