how to get values out of a function??

[miles_rich]

if i want a function to return a alue how would i do it??

so if the function was

function add($num1,$num2)
{
$answer = $num1+$num2;
}

How would imake it so the answer is returned as a value??

would

$value = $answer;

or

$value = add('2','2');

[Bunkermaster]

function blah( val1, val2 ){
return val1 + val2;
}

$foo = blah( 1, 2 );

The latter : $value = add('2','2');

would work, you call the function to perform the task on values passed to it..

<?
function add($num1,$num2)
{
$answer = $num1+$num2;
return $answer;
}

echo add(2,4);
?>
