creating number, certain charachters long

[davieboy]

i am trying to generate a barcode

this has to be 36 Charachters long

how does one go about getting the code to randomise and be the corect number of charaters long?

have got the random bit working fine, just not the characters

$number = '';
for ($i = 0; $i < 36; $i++) {
    $digit = rand(0, 9);
    $number .= $digit;
}
echo $number;

To include letters:

$alpha_arr = range(a, z);
$digit_arr = range(0, 9);
$char_arr  = array_merge($alpha_arr, $digit_arr);
$str = '';
for ($i = 0; $i < 36; $i++) {
    $char = $char_arr[rand(0, count($char_arr) - 1)];
    $str .= $char;
}
echo $str;
