Re: [PHP] similar to shuffle()

[Chana Black]

I had the same problem... I wrote a function that does this:

function scramble(&$array)
{
         // scrambles the elements of a one dimentional array
         // written by cblack ([EMAIL PROTECTED])
         // in php3 >= 3.0.8, there's a function called shuffle that does this
         for ($i=0;$i<sizeof($array);$i++)
         {
                 // seed random number generator
                 srand((double) microtime() * 1000000);

                 // store whatever is in $array[$i] in a temp var
                 $temp = $array[$i];

                 // generate a random number to swap with
                 $newvalue = rand(0, sizeof($array));

                 // swap values
                 $array[$i] = $array[$newvalue];
                 $array[$newvalue] = $temp;
         }

         return 1;
}

Feel free to modify...
