<?
function yrsolder ($person=0)
{
$george = 29;
$bobby = 27;
if($person==0) // george
{$yrs = ($george-$bobby);}
if($person==1) // bobby
{$yrs = ($bobby-$george);}
}
echo "I am ".yrsolder(1)." years older than Bobby!";
?>
Will output:
3I am older than Bobby!
instead of
I am 3 years older than Bobby!
This is because php will call functions when they are referenced, before an echo statement is
called. So if you have an echo statement inside the function, that echo statement is called first,
then the echo statement that originally called the function.
