[SOLVED] get the 'http://' section from the url bar..

[Dragen]

Hi,

I'm sure this is really simple, but I'm trying to get the full url from the address bar.

I'm using this:

$url = $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];

which works fine except I'm wanting to check whether the page is 'http://', 'https://' or even 'ftp://' and add that to the beginning.

At the moment I get something like:

www.mydomain.com/folder/index.php

 

Can anyone help me get the protocol? (I think that's what it's called... )

Thanks

You could try $_SERVER['SERVER_PROTOCOL'], test the variations though, it's not quite what you want but you'll see!

[Dragen]

ah thanks! seems pretty much what I need.

I can't test it much as I don't have access to a secure server for testing https or a ftp server, but running through http gives me 'http/1.1'.

 

Do you know if it always outputs the protocol name followed by a slash and revision number?

[rarebit]

Yes it does (it's the protocol), but it doesn't change when it's https, you need to check for it using:

if (strcmp($_SERVER['HTTPS'], 'on')==0)
{
print "HTTPS is ON<br>";
}

Not checked ftp yet...

thanks.

I actually just looked up $_SERVER['HTTPS'] and found this on php.net..

echo sprintf('http%s://%s%s', (isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == TRUE ? 's': ''), $_SERVER['HTTP_HOST'] , $_SERVER['REQUEST_URI']);

 

Which works great. I'm forgetting about ftp, because no-one should really be using it for my code anyway.

Thanks!

Well, FTP servers cannot run PHP scripts, so you couldn't possibly use it for anything.

hehe fair enough.. to be honest I've never mucked about with ftp servers so I didn't know whether they could or not..
