How do i assign a variable in a function for use outside of

[gotornot]

Hi

 

I am trying to write an email function and ive hit a snag

 

I need to assign 2 variables in the function with the content of an html email and text email.

 

Is there anyway of declairing a variiable within a function for use outside of it in the code below?

Look to the section that describes the global keyword

Seriously, you just have to scroll down a little bit

 

$a = 1;
$b = 2;

function Sum()
{
    global $a, $b;

    $b = $a + $b;
} 

Sum();
echo $b;
?>

You are actually much better off having your function return a value it has worked on. eg;

 

function foo($a) {
  return $a;
}

$a = foo("bar");
echo $a;
