Question

I have a text-box, where I will be getting URL

URLs can be entered in any of the following format:

 example.com
 www.example.com

 http://example.com
 http://www.example.com

 example.com/
 www.example.com/

 http://example.com/
 http://www.example.com/

I need to convert them to single

http://example.com/

How can I do it, there must be simple way round to do it, right?

Answer 1

If you really only expect this few variations you could solve this, with a regex. For example

<?php
// $input = The data you retrieved

$output = preg_replace('#^(?:http://)?(?:www\.)?(.*?)/?$#', 'http://$1/', $input);
echo $output;

I didn’t test it, but should work.. If not, let me know 🙂

** Edit **
Just tested it. Works fine. At least for the formats you specified.
