Urls test

[MarikaBBB]

Description:

This PR is in relation to Issue dxw#19 and implements unparse_url() function to complement PHP's native parse_url(). While parse_url() parses a URL into its components, PHP does not provide a built-in way to reconstruct the URL, which is why this function is needed.

Change:

• I created a PHPUnit test in urls_test.php to check the functionality before writing the actual implementation into the src folder.
• I created Urls.php file in the src/ folder to implement the unparse_url() function.

Reference:

• https://stackoverflow.com/questions/4354904/php-parse-url-reverse-parsed-url/31691249#31691249 provided in the issue PHP has parse_url() but no build_url() dxw/php-missing#19

Consideration:

• This implementation is based on the Stackoverflow solution (see link above)
