guys need a bit of help here..

I'm trying to create a class where in that class i'm using some of the php's global variables. I don't understand why the variables doesn't contain any value if used inside a class. Here is a sample:

testclass.php contains:

PHP Code:

<?

class test {

   function test() {

      echo "test:" . $HTTP_SERVER_VARS["SERVER_NAME"];

   }

}

?>

Then test.php contains:

PHP Code:

<?

  include("testclass.php");

  $myTest = new test;

?>

This should display "test:MyServerName" but i only get "test:". But when I try to place the script

PHP Code:

echo "test:" . $HTTP_SERVER_VARS["SERVER_NAME"]; 

outside the class or place it in the test.php, it works fine.

Can anybody tell me why is it so? Or did I miss something? Is there something wrong with the code?

Thanks.

This works for me:

PHP Code:

class test {

   function test() {

    global $HTTP_SERVER_VARS;

      echo "test:" . $HTTP_SERVER_VARS["SERVER_NAME"];

   }

}

Cool! Works fine. Thanks Vulture.
Can you/someone tell me why we need to declare global HTTP_SERVER_VARS in a class? coz it works even if we dont declare it as long as its not inside a class..

Because your creating a function (the class isn't the cause here) which you may want to use different variables, you have specify exactly what variables the function is permitted to use/alter. You could've sent the variable like this

PHP Code:

function test($name) {

          echo "test:".$name;

}

test($HTTP_SERVER_VARS['SERVER_NAME']); 

However, that would not be practical in this example since your sending a in-built variable which you could include in a "global" statement reducing the need to provide it as an argument. Hope thats explained it better, if not, i'll try and clear it up some more.
