Help in finding whats wrong in my code

[bprof]

Hi,

I have a problem in this code I don't know why?


[code]function shufelmycards() {
        // we have to use some random stuff here.
        for ($i = 0; $i < 5; $i++) {
        $num = rand(1000,9999);
        mt_srand ((double) microtime() * 9999999);
        $allcards = mt_rand (0,35);
        do {
            mt_srand ((double) microtime() * 9999999);
            $allcards = mt_rand (0,35);
        } while (in_array($allcards,$mycards));
        array_push($mycards,$allcards);
        $oponentcards[$i] = $allcards;
        }
    }[/code]

Each time I call this function I get this error message:

in_array(): Wrong datatype for second argument in

array_push(): First argument should be an array in

I've already declared both arrays(mycards, allcards array) early in the script

[code]$mycards = array ();

$oponentcards = array ();[/code]

Did you create the mycards variable outside of the function? If you did you need to add the following bit of code after you define your function:
[code]function shufelmycards() {
    global $mycards; // add this line![/code]

Now your function will be able to access the $mycards variable.

Variables dont have global scope when being used inside a function. In order for your variables to be accessable from the function you need to declare them as global.
