Hi Folk

Consider the two code options below. I want to know if it makes more
sense, in theory, to pass a variable or to make it global

FIRST OPTION --

....

$data = 5;

$data = dosomething($data)

....

echo $data;
exit();

function dosomething($data) {
$myval = 3;
$data = $data + $myval;
return $data;
}

SECOND OPTION --
....

$data = 5;

dosomething()

....

echo $data;
exit();

function dosomething() {
global $data;
$myval = 3;
$data = $data + $myval;
}
