[xbl1]

Hi;I'd like to ask you how i get a varibal value from url.the url is "http://mysite.com/country/Category.php?page=1/"i want to get the page value.i tried the following, it does not work.echo $_GET["page"];echo $_POST["page"];echo $_REQUEST["page"];could anyone tell me hoe to get the value of page, please.

It's:echo $_GET['page']; but your URL has an unnecessary / at the end.

You can use $_GET['page'] or $_REQUEST['page']. You will not get information from the URL with $_POST['page'], you would need to submit a form. $_REQUEST will get information from $_GET, $_POST, and $_COOKIE.

Whats the different when you use single quotes instead of double cause i use double and it work fine eg

$name = $_GET["name];

[Ingolme]

Single or double quotes don't make any difference.

Single or double quotes don't make any difference.

Not completely right. Double quotes allow you to refer to PHP variables within the strings they encompass, whereas everything in single quotes is outputted literally. The overhead of using double quotes in strings with no variable references is unnoticeably small though (from one test that I made it's under 0.1ms at 1 million iterations), so if you can't make it a habbit to use single quotes - so be it.

let me see the form, and $_REQUEST is enough.

print_r isn't an array, it is a function - try

print_r($_REQUEST['page']);

I'm not too familiar with mod_rewrite, but that rule might be chopping off the querystring - what do you see in your browsers URL bar when you click on a link to category.php ?

it shows with the "http://www.mysite.com/country/Category.php?page=1"

[Synook]

That is correct - try

print_r($_REQUEST);

Oh btw - what version of PHP are you using?
