Question

I want to generate a random number in PHP where the digits itself should not repeat in that number.
Is that possible?
Can you paste sample code here?
Ex: 674930, 145289. [i.e Same digit shouldn’t come]
Thanks

Here is a good way of doing it:

$amountOfDigits = 6;
$numbers = range(0,9);
shuffle($numbers);

for($i = 0;$i < $amountOfDigits;$i++)
   $digits .= $numbers[$i];

echo $digits; //prints 217356

If you wanted it in a neat function you could create something like this:

function randomDigits($length){
    $numbers = range(0,9);
    shuffle($numbers);
    for($i = 0;$i < $length;$i++)
       $digits .= $numbers[$i];
    return $digits;
}
