functions in PHP


how can i get the variable which is the result of a function?
for example;

<?php
$number1=10;
$number2=20;
$number3=50;
function calc ($number1,$number2) {result1=$number1 * $number2;return $result1;}
function finalcalc ($result1,$number3) {result2=$result1 + $number3;return $result2;}
print calc( $number1,$number2);
print "<br>";
print finalcalc($result1,$number3);
?>



Why i can't see result2,although i see result1?
How can i get $result1 from the function?
------------------------------------------------------------------------------------------------
I have another question that how can i change the variables from browser(one by one or alltogether)?(especially in this example)

PHP Code:
<?php
$number1
=10;
$number2=20;
$number3=50;
function 
calc ($number1,$number2) {result1=$number1 $number2;return $result1;}
function 
finalcalc ($result1,$number3) {result2=$result1 $number3;return $result2;}
$result1 calc$number1,$number2);
echo 
$result1;
echo 
"<br>";
echo 
finalcalc($result1,$number3);
?>
In the function calc, $result1 is not exported because it's a member variable of the functions, and the scope is only in the function body. And after the functions finished, it's automatically unset. So that code should do the thing.

Cheers,
gamehack
