i need to make a function to read the result from another function. what i did is an example with the calculation of a+b. what i whant to do is to be able to echo the value of a+b with the function main.
where is the mistake?

function main()
{


a=5
b=10

calcul (a,b)


return val
}


function calcul(a.b)
{
a+b
return val
}

c'ets simple : il manque les instructions genre print ou echo ;-))

function main()
{


$a=5
$b=10

$val=calcul ($a,$b);


return $val;
}


function calcul($a.$b) {
$res=$a+$b;
return ($res);
}

to print :

echo "le résultat est $val
";

dans main.php après l'affectation de $val=calcul($a,$b);

as you can see i had the concept write. maybe i made some mistakes in the variables names. i have no ideea why it wasn't working.
you had a litle mistake in your code to. in the calcul you put a dot insted of comma . here is the working code :

<?

function main($a,$b)
{
$val=calcul($a,$b);
return $val;
}

function calcul($a,$b) {
$res=$a+$b;
return $res;
}

$x=main(5,5);
echo "le résultat est $x
";


?>

thanks.
