I'd just look in $_GET.

The value will show up as an array index with no accompanying value in that array.

For example, if you point your browser to:

test_show_get.php?3

then $_GET will contain:

Array
(
[3] =>
)

hum.. :#

if i do a count($_GET) when i use .php?a i get 0 but then i use .php?a=b i get 1

so i can't go there and grab the key because it's not even in the array right ? :

That's odd.

Using the following test script, test_show_get.php:

<?php
print '<pre>';
print 'Count:' . count($_GET). &quot;\n&quot;;
print_r ($_GET);
?>

When I point my browser to test_show_get.php, I get:

Count:0
Array
(
)

But when I point my browser to test_show_get.php?a, I get:

Count:1
Array
(
    [a] => 
)

This is on a LAMP (RH9/1.3.28/4.0.14/4.3.4) box. What version of PHP are you running?

It's probably a revision problem.

It sounds like a change in the way PHP parses the URL. To be honest, you shouldn't trust the solution I gave you unless you know for a fact that you are seeing a but that has been fixed. For all we know, the output I'm getting is wrong and yours right.


Here's a better answer. Look in $_SERVER['QUERY_STRING'] instead.

In the case of script.php?a, that variable will contain "a".

Just out of curiosity, on your version of PHP, what do you get in $_GET if you invoke the script from the browser as test.php?a&foo=3 ?

.php?a&foo=3

Count:1
Array
(
[a] =>
)

wow that's odd :x lol

that $_SERVER['QUERY_STRING'] was just the thing i was looking for i used to use it but then forgot it..

thanks

Okay. I think I can characterize the problem with $_GET as a bug in your version of PHP.

You should think about upgrading.

If you're just looking to pass a single variable with the URL, you can use $_SERVER['QUERY_STRING'] to get it. It should just pass anything after the ? in the URL.

Using the following as testparse.php
<? PHP
$urlvar = $_SERVER['QUERY_STRING'];
print &quot;$urlvar was typed after the URL&quot;;
?>

If called with testparse.php?foo the resulted output is

foo was typed after the URL

Didn't I already say that, and didn't jamesp0tter agree that that was the solution he was looking for?

Ok, so I'm sleepy. I either missed that chunk or I had the page open so long before I finally got around to finishing the thread. Had a small fire to put out at work.
