Making an array of 'n' digits

[saeed_violinist]

Dear friends,

 

It's not just the way of coding but I want to now how can we make an array of "n" digits, for example if "n" equals "3" then we should have an array of 100 to 999, and for "n" equal 2 we should have array of 10 to 99.

 

Any help or ideas how to do this will be appriciated!

$n = 3;

switch($n) {
  case 2:
    $array = range(10,99);
  break;
  case 3:
    $array = range(100,999);
  break;
  default:
    $array = array();
  break;
}

print "<pre>".$array."</pre>";

Thanks, it seems to be a good idea, But actually I want to do it with any value for "n". maybe user enter 10 as "n" so we need to have array of 1000000000 to 9999999999.

 

like this, we need to have a large switch statement, I am looking for a gerenarl way or formula for this.

Ah. Here you go

$n = 3;
$x = str_pad(1, $n, 0);
$y = str_pad(9, $n, 9);

$array = range($x, $y);
print "<pre>";
print_r($array);
print "</pre>";

$n = 10;

$low = pow(10,$n);
$high = pow(10,$n+1)-1;
$array = range($low,$high);
