    [Scheme] => http
    [Host] => hostname

Notes

Note: This function cannot be used for relative URLs.

Note: Parse_url () is specifically used to resolve URLs rather than URIs. However, there is an exception to the need to comply with PHP's backward compatibility, which allows three slashes (file:///...) for the file://protocol. ）。 No other agreement can do that.
