passing variables between two functions

[xfezz]

function one($y,$z) {
[b]xyz[/b] = some query from the database;
some other calculations using variables $y and $z;
}

function two($yy,$zz) {
some other calculations using variables $yy and $zz;
newVar = [b]xyz[/b]+ 4;
}

I need to use variable xyz to do a calculation in function two. how do I pass one variable to another function? or would I have to run the same query again in function two?

A few ways...

Either call function two within function one, or return $xyz as a result of function one and pass it into function two that way.

Of couse you could also use globals but I wouldn't recommend it.

[code][code]
<?

function Add($x, $y) {
$result = $x + $y;
return $result;
}

function Subtract($returnedRESULT) {
echo $returnedRESULT;
}


$returnedRESULT = Add(2, 3);

Subtract($returnedRESULT);

?>

I don't know if more than one value can be passed. maybe if you put them in an array? [/code]
