Self referencing

[TreatmentPlant]

How can I write a PHP code to find the URL on which the code the itself
is running?

Sorry about the question: it's a bit difficult to describe, so here is
what I am trying to achieve...

....in sort of LogicCode
If this is NOT the home page then
associate the company logo with a link to the home page
else
just display the logo without any linking reference.



TIA

If you're running PHP as an Apache module, use $_SERVER["REQUEST_UR I"].
You can combine this with $_SERVER["HTTP_HOST"] if you run it on different
hostnames (and that's important to you).

Cheers,

On the home page have something like this

<? $page="home" ?> and on the other pages
<? $page="nothome" ?>

Then where you want the image to be have

<?

if ($page=="nothom e") {
Code fopr company logo and link to home page code
}
else
{
Code for logo withouth link to home page
}
?>

Actually, all he need do is on the homepage
<?php $page="somethin g" ?>
and on all pages do
if (isset($page)) {
....
} else {
....
}

But be wary of using it for anything more than changing a link like this,
if you're running with register_global s on (I know, it's not good
practice, but there may still be some old installations or those upgraded
and kept for compatibility).

At least Kevin's version would have checked for the exact value he set
(rather than yours that would be got round with www.foo.com?page=1)

Just pointing it out for less experienced PHPers.

Cheers,


Andy

Thanks all,

I have implemented Kevin's suggestion and it works like a charm.
