Hi, this is the common way to do things:
<?
// declare function
function test($param)
{
$param = $param + 4;
return $param;
}
// option 1 -- prints 48
$param = test(44);
echo $param;
// option 2 -- prints 59
echo test(55);
?>
I *think* you can also make param part of the global array, but this is
totally UNTESTED code -- infact, I've never had the need to use the global
array in this way.
<?
// declare function
function test($param)
{
$_GLOBAL['param'] = $param + 4;
}
// option 1
echo $_GLOBAL['param'];
// option 2
echo $param;
?>
Good luck.
