Question

Whats the best way to do a random “for” without repeating any number?

for ($i = 1; $i <= 10; $i++) {
    echo $i;
}

I think some ways but are so complicated with a lot amount of code..
There is a standard function to do what im willing?

Answer 1

$numbers = range(1,10);
shuffle($numbers);
foreach($numbers as $i) {
    // do stuff
}

That will give you the numbers 1 to 10 with no repetition in a random order.
