A couple of Questions!! Pls

[Forri]

Hi

I would like to ask:

1) if i have the following:

 <?PHP
 
 $Counter = 0;
  
 UPDATEVARIABLE();
  
 echo $Counter;

 [b]function [/b]UPDATEVARIABLE()
 {
   $Counter = 5;
 }
?>

Will the above print out 5 or 0; Does the function update the Variable or update it only within the function?

Ok. for now thats it...then i'll make another question according to the above answer!

Thanks
Nick

Sorry forgot piece of syntax which is the:

global $counter;

before

$counter = 5;

Still awaiting your reply!

Thanks again

Your function will update the global variable $Counter when you include the global statement from your second post.

The scope of variables in PHP is local to a function. Using the global $myVar statement will use the variable from outside the function.
