It seems that parse_url returns an empty host when the scheme is missing:

$url = parse_url("http://www.lalala.com"); print $url["host"];

-> outputs "www.lalala.com"

$url = parse_url("www.lalala.com"); print $url["host"];

-> outputs ""


I tried to reproduce the bug on windows2k, but there it worked just like it should. It could of course also be that I'm a complete idiot since I've only been using PHP for a few days, but the result seems to be persistant.

www.lalala.com isn't a valid url. The docs say nothing about such a case, so it's undefined.

Use var_dump on $url to see what happens, PHP thinks www.bla.com is the path. (both linux 403 & 407, and win32 404pl1)

A warning would be appropriate if the url is invalid, looking into that...

After some thinking: This is expected behaviour!

www.lalala.com is a valid directory-name, and therefore it is a relative-path.

Try this in your browser with a <A HREF>, and you'll see that your browser interpretets it identically.

So this is not a bug. (In the manual, it should be clarified that also partial urls are accepted, and some examples?)

Changed to docbug.

This bug has been fixed in CVS. You can grab a snapshot of the
CVS version at http://snaps.php.net/. In case this was a documentation 
problem, the fix will show up soon at http://www.php.net/manual/.
In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites.
Thank you for the report, and for helping us make PHP better.
