PHP Header Redirect with registers_global = off

Hi All,

I'm looking to use a php script, similar to the one discussed here to redirect visitors to different websites.

Now, I can get this script working if I turn register_globals on, however, I hear there is security issues with this. So, can anyone advise me about how I can modify the following out.php file in order for it to work with register_globals off?

<?php
if ($m == "google") {$link = "http://www.google.com";}
if ($m == "yahoo") {$link = "http://www.yahoo.com";}
if ($m == "live") {$link = "http://www.live.com";}

header("Location: $link"); // Jump to the url above
exit();
?>

Code (markup):

Eg. the redirect URL would be /out.php?m=google

Thanks in advance!

 

just use $_GET to get the querystring

ex: $m = $_GET['m'];

 

an example of what shineDarly means:

<?php
if (isset($_GET['m']))
   {
      $m = $_GET['m'];
      if ($m == "google") {$link = "http://www.google.com";}
      if ($m == "yahoo") {$link = "http://www.yahoo.com";}
      if ($m == "live") {$link = "http://www.live.com";}
      header("Location: $link"); // Jump to the url above
}
?>

PHP:

here is a version that allows for unlimited links

<?php
if (isset($_GET['m']))
    {
        $url=Array(
                    "google"=>"google.com",
                    "yahoo"=>"yahoo.com",
                    "live"=>"live.com",
                    );
        $m = $_GET['m'];
        foreach ($url as $this_m=>$this_url)
            {
                if ($m == $this_m)
                    {
                        header("location: http://".$this_url."/");
                    }
            }
}
?>

PHP:

or

<?php
if (isset($_GET['m']))
    {
        $url=Array(
                    "google.com",
                    "yahoo.com",
                    "live.com",
                    );
        $m = $_GET['m'];
        foreach ($url as $this_url)
            {
                if ($m == substr($this_url,0,strlen($m)))
                    {
                        header("location: http://".$this_url."/");
                    }
            }
}
?>

PHP:

 

Worked perfectly. Thank-you both... +rep given to both of you.

 

Hey guys,

I know this is a very old thread. Found it through Google and need help with modifying this script. This is what I wish to do:

http ://site1/out.php?id=http ://site2/

When the user clicks the above link, the script should simply redirect to http ://site2/

For that matter, I tried to modify the script in out.php file like this:

<?PHP
$id = $_GET['id'];
header("Location: $id");
exit();
?>

PHP:

As per my understanding, $id variable pulls the information from id using GET. Then header should redirect to the link stored in $id variable. Although this works for simple urls like:

http ://www .site1.com/out.php?id=http ://www .site2.com/

But it doesn't work if there are more parameters in the link:

http ://www .site1.com/out.php?id=http ://www .site2.com/a=10&b=11&c=12&d=13

My purpose is to just make the outgoing links a part of my website. When the user clicks the link, the script should simply redirect to Site2.

I do not wish to use the out.php too much and keep adding links to it, it will be very time consuming. So, what would you suggest?

Appreciate any help you guys can provide.

Regards.
