functions

[ruach]

i know that this is a no-brainer, but i can't figure it out.

i have a script that calls a function to do so error checking. The function looks like this:

<?
function is_valid($var1, $var2){
  if($var1 > 0 && $var2 = 5){
     echo "your number is too high";
   }
   else{
      $passed=1;
     // ?
   }
}
?>

I want the function to return the $passed variable to the script that called it. So I can test if $passed=1 or not.

how do i do that?

-thanks

<?
function is_valid($var1, $var2){
  if($var1 > 0 && $var2 = 5){
     return false;
   } else{
      return true;     // ?
   }
}
?>

If $var1 > 0 and $var2 = 5, it will return false, otherwise, it will return true.

You can use something like that...

<?
if(function_is_valid($number_1, $number_2)) {
 // Code if OK
} else {
 // Code if NOT ok
}

Got it ?

I forgot...

You also could replace

$passed = 1;

by

$GLOBALS["passed"] = 1;
