php - How to randomize an array without duplicating an integer -


for example if have this: 

<?php $b = array(100); ($i = 1; $i <= 100; $i++) {     $b[$i]=$i; } ?>

how randomize numbers without duplicating them?

your approach work if shuffle array:

for ($i = 1; $i <= 100; $i++) {     //$b = array(100); //why here?     $b[$i] = $i; } shuffle($b);

however it's simpler:

$b = range(1, 100); shuffle($b);
