Retrieving Full URL

[Pennimus]

I found this piece of code that will do it

http://dev.kanngard.net/Permalinks/I...507183447.html

However this seems quite long-winded for what I imagined would be quite a basic function. Is there a shorter way to do this (something akin to $_SERVER[PHP_SELF] but for the full URL)?

PHP Code:

$url = "http://" . $_SERVER['HTTP_HOST'] . "/" . $_SERVER['PHP_SELF'] . "/" . $_SERVER['QUERYSTRING'] . "/"; 


or using javascript

window.document.location.toString()

Umm there are a few errors there, and that won't catch the directories though. Its much better to use:

PHP Code:

 echo "http://" . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'] . "?" . $_SERVER['QUERY_STRING']; 


Right?

Thanks for the nudge in the right direction guys, I have a working version now.

Error in mine to, you don't need $_SERVER['QUERY_STRING'] and if you want a function to do it like. fetch_url() to use where ever like even in a form like:

<form name="form1" method="post" action="<?php echo fetch_url(); ?>">

And that sort of function is easy and a very basic so its even good to build off of.

PHP Code:

<?php

function fetch_url() {
  $url = "http://" . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
  return $url;
}

// Example again
echo "<a href=\"" . fetch_url() . "\">" . fetch_url() . "</a>";

?>

I get the same output from PHP_SELF as I get from REQUEST_URI.
Both show the directories when concatinated within a string containing HTTP_HOST, PHP_SELF and QUERY_STRING to echo the full url for the current page.

What are the supposed differences and in what circumstances do they become evident?

$_SERVER['REQUEST_URI'] shows only the path to the file, whereas $_SERVER['PHP_SELF'] gives the path to the file as well as the query string. You should be able to use this:

PHP Code:

$uri = 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF']; 


to get your URI as well, although either method is fine.

Hmmm, $_SERVER['PHP_SELF'] doesn't include the query string when I try it. To reference/echo the query string, I explicitly need to use $_SERVER['QUERY_STRING'].

Perhaps it's a version thing. I'm running PHP 5.01.

What was wrong with the version you linked to? It even gets the protocol and port number by the looks of it. It doesn't matter if it's a little complex when it's tucked away in a function

Edit: And I'm pretty sure PHP_SELF doesn't include the query string in any version of PHP.

$_SERVER['PHP_SELF'] will give you the EXECUTING script, so if you are using mod_rewrite, you may have some problems.
$_SERVER['REQUEST_URI'] gives the actual request (as entered in the address bar)

$_SERVER['REQUEST_URI'] does give the query string. It gives everything after the domain. Lol.

Indeed. Example from a phpinfo.php:

_SERVER["QUERY_STRING"] query=string&query2=string2
_SERVER["REQUEST_URI"] /phpinfo.php?query=string&query2=string2
_SERVER["SCRIPT_NAME"] /phpinfo.php

_SERVER["REQUEST_URI"] /phpinfo.php?query=string&query2=string2
_SERVER["SCRIPT_NAME"] /phpinfo.php

_SERVER['HTTP_HOST'] => ameirkanmetz.rave5.com
_SERVER['QUERY_STRING'] => a=b&b=b
_SERVER['REQUEST_URI'] => /blah/demo/test/what.php?a=b&b=b
_SERVER['SCRIPT_NAME'] => /what.php

hii thanks for the above info,
but its not satisfying my requirement

what i need to trace is not ust url with query strin but i also need to trace #href

i.e. if my url is
http://jigishthakar.com/?p=2#cid

then till
http://jigishthakar.com/?p=2 ur code works fine but now how to trace #cid ?
