global variables

[jonniejoejonson]

$a=3;

$b=4;

 

i have a function

 

function addUp($a,$b)

{

$c=$a+$b;

return $c;

}

 

however is there a way to make $b global so that it doesn't have to be defined in the function?

Generally its poor design but...

 

function addUp($a)
{
  global $b;
  $c=$a+$b;
  return $c;
}
