PHP gets the contents of a specified number of cells of a specified array in a random array

PHP gets the contents of a specified number of cells of a specified array in a random array
I tested it in the local APMServ 5.2.6 environment and it could be displayed randomly, but when I uploaded it to the US space, the number 5 was displayed instead of random. Please tell me how to modify it? Or what function can be used to achieve random replacement?

$numbers = range(1, 100); //range is to list 1 to 100 into an array
$result = array_rand($numbers,100); //array_rand randomly takes out the array in order The specified number of cells in
echo $result[5]; //Get the specified number of cells in the randomly retrieved array
?>
