Random Numbers Back In To The Pool

Anon

Hey Guys,

Have created some code below, the problem is that I would like to re-insert the numbers back in to the pool, with the possiblity that the same number could occur in all the draws... Any help would be appreciated eh....
Thanks,
Grunta

$start = 1;
$end = 5;
$draws = 5;

$nums=range($start,$end);
print 'All Numbers "ARE" Back in Pool Pool Numbers Range from ' . $start . ' to ' . $end . ' with ' . $draws . ' draws allocated And the Number(s) are as follow....... ';

shuffle ($nums);

for ($count=0;$count<$draws;$count++)
{
print '' . $nums[$count] . ' ';
}

Change your randomizer.
Instead of shuffling your array and getting 5 sequencial elements;

don't shuffle your array but create a random number in the specified range, and select that element from your array.
This means you select a new random number each draw.
This is effectively the same as re-shuffling your array between draws (which is bound to be slower than generating a new random number).

Vincent,

Thanks for that... would you perhaps give me a sample as this random and shuffle function is 'O' so new to me....

Thanks,

Hmmm no I don't think so :-)

How to generate a random number is described in the manual, it's really very simple.
