information from refered URL

[onlyican]

Hey guys

I am tryna work on a script
I need to know the domain and the page of the referer

I am kinda doing this a long winded way,

My Example

[code]
<?php
$passed_by = $_SERVER['HTTP_REFERER'];
if($passed_by){

$parts_passed = explode("/", $passed_by);

//Remembering a passed will have http://, as theres 2 / in http, I want third in array
//Remembering an array starts on 0 in php, so it will be 2
$domain_passed = $parts_passed[2]; //

$num_parts = count($parts_passed);
$last_in_parts = $num_parts - 1;
$page_passed = "";
for($i = 3; $i < $last_in_parts; $i ++){
$page_passed .= $parts_passed[$i]."/";
}

$page_passed .= $parts_passed[$last_in_parts];

}else{
//Gonna do something here, might be a fault or direct hit
}


?>
[/code]

NOw with that code, I think it will work
For example, domain passed is http://localhost/mypage.php;
then
$domain_passed will be "localhost";
and $page_passed will be mypage.php

Example being
http://www.example.com/folder/mypage.php
Then
$domain_passed WILL be "www.example.com";
$page_passed WIll be "folder/mypage.php
Which is what I want

BUT

is there a better way to do this

You might want to look at the parse_url() function:

I keep doing this

Make nice functions when PHP has one already made

Thanks

Does this grab
www.example.com
or example.com
or depending if www. is in use?

It do not need to have www. prepended.

ok, thanks for that, it really really did not answer my question

Read::

I am using $_SERVER['HTTP_REFERER'];
if I parse that using url_parse();
then I grab the host
$parsed_url = parse_url($_SERVER['HTTP_SERVER'];
$host = $parsed_url["host"];

Now say that they came from
http://www.example.com/mypage.php
then I come from
http://example.com/mypage.php (NOTE: No www.)

Are hosts the same
or is host on one example.com and the other www.example.com?
