Hello,
I have a pool of values I have to use, but I only have the first and last value of the range: 9CF90000-9CF910CB and I need all the values between them.

How can I get them or generate them?

Thanks!!

I did a quick google search using hexadecimal, and it gave a javascript code to convert any number to hex...

If you put this in a loop somehow, starting with "X" and ending in "Y"...

Although, I don't know if it would work because I don't know javascript.

Code: [ Select ]
for($i = 0x9CF90000; $i < 0x9CF910CB; $i++)
{
$hex = sprintf('%X', $i);
}
  1. for($i = 0x9CF90000; $i < 0x9CF910CB; $i++)
  2. {
  3. $hex = sprintf('%X', $i);
  4. }
Strong with this one, the sudo is.

If you read about integers, you'll learn about the hexadecimal syntax I used.
http://www.php.net/manual/language.types.integer.php

I used that syntax because you were working with hexadecimals anyway. :)
