Description:
------------
parse_url("http://example.com:qq");

Array
(
    [scheme] => http
    [host] => example.com
)

The port number "qq" is not included, so based on this output there is no way
to determine in later code that the URL was invalid.

Relatedly, the port number is returned as an int, while the manual says that
every component is returned as a string.

Partially bogus, as the documentation says, "parse_url" is not meant to validate URLs. Use the filter extension for that.

The second part about it returning an int is true though.

I didn't expect parse_url() to validate the URL, but I did want it to
give me all the pieces that it found so I could validate or compare
them with other URLs myself.

Since internally php_url has an integer field for the port, I guess
it's too difficult to make it return the original port string.

Regarding the filter extension, the above URL passes validation (see
bug #49197).
