PHP, Structures and Functions, Fundamental Syntaxes

This function parses a URL and returns an associative array containing any of the various components of the URL that are present.

The values of the array elements are not URL decoded.

This function is not meant to validate the given URL, it only breaks it up into the above listed parts.

Partial URLs are also accepted and this function tries its best to parse them correctly.

Invalid characters in the provided URL, are replaced by underline character, ( _ ).
