PHP: generate a number from xyz0000 to xyz9999

I am trying to generate a list of numbers (that I can use in a for/foreach cycle).

Any number should be 10 digits long and have an initial prefix (i.e. 0851)

0851xxxxxx
and go from 0851000000
to
0851999999

range('0851000000','0851999999')

However this array will take as much as 84MB in memory (as reported by memory_get_usage(1))

Less memory consuming way is to generate these numbers on the fly, while you iterate in your loop.

For example

for($a = 851000000; $a <= 851999999; $a++) {
  $number = '0'.(string)$a;
  doSomethingWith($number);
}

For a random generation, use the following code. Use Mchl's answer if you want the entire list of possibilities.

$str = sprintf("0851%06d", rand(0, 999999));
