使用$ _GET从URL中提取文本

I have a URl that looks like this:

http://somedomain.com/article_view.php?articles=ViewAll

I am then trying to extract when articles=ViewAll using:

if(isset($_GET['articles']) && $_GET['articles']=='ViewAll'){
//do something here
}

It doesn't seem to be working as it never drops inside the if statement. I assume my syntax is wrong but as a newbie I can't see my error. Your help much appreciated.

this works for me try it:

 if(isset($_GET['articles']) && ($_GET['articles']=="ViewAll"))
            {

            }

try checking the rest of your code or paste the rest of the code here so I can see what may be wrong
