Basic PHP <> question

[k0zz]

Lets say I have a variable $number. This variable can equal anything from 1 to 10,000,000

Now I want to assign $number a level, based on the following incrementation:

0-999 = Level 1
1,000-1,999 = Level 2
2,000 - 9,999 = Level 3
10,000 - 19,999 = Level 4
20,000 - 29,999 = Level 5
30,000 - 39,999 = Level 6
40,000 - 49,999 = Level 7
50,000 - 74,999 = Level 8
75,000 - 99,999 = Level 9
100,000 - 124,999 = Level 10
125,000 - 149,999 = Level 11
150,000 - 199,999 = Level 12
200,000 - 249,999 = Level 13
250,000 - 299,999 = Level 14
300,000 - 349,999 = Level 15
350,000 - 399,999 = Level 16
400,000 - 449,999 = Level 17
450,000 - 499,999 = Level 18
500,000 - 549,999 = Level 19
550,000 - 599,999 = Level 20
600,000 - 649,999 = Level 21
650,000 - 699,999 = Level 22
700,000 - 749,999 = Level 23
750,000 - 799,999 = Level 24
800,000 - 849,999 = Level 25
850,000 - 899,999 = Level 26
900,000 - 949,999 = Level 27
950,000 - 999,999 = Level 28
etc. etc. etc
etc. etc .etc


Is there any easy way of doing this, so as to not repeat an If statement over and over again?

Thanks.
