Help With Functions

[Anon]

How would I get this to work... when I try it I get no result

function funcName($first,$second) {

$calc = $first * $second;

}

funcName(5,76);
echo $calc;

thank for your time.

You either need to print the result from within the function (very silly) or include a return statement.

function funcName($first, $second) {
$calc = $first * $second;
return $calc;
}
print funcName(5,76);

man thats lame :\

I suggest you to grab some information about variable scope. It will help you a lot to improve your programming skills.

In a function, all variables have a local scope. In your example, $calc means something as long as you are in funcname function. As soon as you re-enter the function, the $calc value is a brand new variable.

If you want to make it short and sweet, do this:

function funcname($first, $second){
return $first * $second;
}

And make your call this way:
echo funcname(5,76);

No, that's just how scoping rules work - in most languages, not just PHP

This also works

function funcName($first,$second) {
GLOBAL $calc;
$calc = $first * $second;

}
funcName(5,76);
echo $calc;
