return() isn't working with ...

[Anon]

Hi,

I wrote a function where I want to return a variable that is an array. This is what I did:

//$back_data[valid] = "valid";
//$back_data[userid] = $result[user_id];
//return $back_data;

So, I set array "valid" with the string "valid" and set array "userid" with the resulted user id, which is an integer. And then I return the whole variable (containing the arays). When I want to print the first array, it does ok, while the second array ("userid") does not print, meaning that it probably wasn't returned. Is there a trick to this so it returns all the arrays???

Thanks a lot.
Ilir.

P.S.
I put the comments in front of the code just so the phorum-Script won't break out.

How about this:

$back_data = array(
"valid" => "valid",
"userid" => $result[user_id]
);

Oh wait, I just remembered you can't return an associative array in php, only indexed arrays, so you would need to do something like this:

function myFunction() {
$var0 = "This is how";
$var1 = "to return multiple";
$var2 = "values from";
$var3 = "a function!";
return array($var0, $var1, $var2, $var3);
}

$myArray = myFunction();
echo $myArray[0];
echo $myArray[1];
echo $myArray[2];
echo $myArray[3];

Output:
This is how to return multiple values from a function!

Hope this helps!
