I would do it like this:
$arr = array_fill(0, 40, 0);
array_walk($arr, function(&$v, $k) { $v = rand(60, 69); });
That will provide you with an array containing 40 elements, each a
random integer between 60 and 69:
print_r($arr);
Array
(
[0] => 60
[1] => 69
[2] => 63
[3] => 63
[4] => 64
[5] => 65
[6] => 68
[7] => 67
[8] => 67
[9] => 67
[10] => 63
[11] => 69
[12] => 65
[13] => 60
[14] => 68
[15] => 62
[16] => 67
[17] => 65
[18] => 60
[19] => 65
[20] => 62
[21] => 69
[22] => 69
[23] => 64
[24] => 68
[25] => 65
[26] => 69
[27] => 66
[28] => 61
[29] => 69
[30] => 61
[31] => 61
[32] => 68
[33] => 64
[34] => 64
[35] => 63
[36] => 60
[37] => 63
[38] => 60
[39] => 67
)
