Republicans across America are asking, just what does John Kerry mean by passing the global test? In order to help explain the issue, I've created this simple program in PHP.

function gT (  )
{
 return ;
}

 = true;

echo gT (  ) ? "You passed the global test!" : "You failed the global test!";

As you can see, the function gT() will return true if the global variable was successfully passed to the function. I hope this clears things up.
