Re-read the docs on the "return" statement
<http://www.php.net/manual/en/function.return.php>. A few pointers:
A) As soon as a 'return' is encountered, function execution ends; it will
never get to the lines containing additional returns.
B) To return multiple values in a single 'return' statement, return an
array variable.
C) 'Return' does not set variables in the global scope for you; it's up to
you to explicity set a variable.
function myFunc()
{
...
return array ($one, $two, $three);
}
$returned=myFunc();
echo "{$returned[0]}, {$returned[1]}, {$returned[2]}";
