extracting just a piece out of a 13digit number

[GremlinP1R]

Hai there. I'm trying to get just 2digits out a 13digit number.
The number looks as follow 1234567890123 now I only whant it to show nuber 56.
How can I do this? Can any one pls help me!

What I tryed were
$num = $row['num'];
$nu = ereg_replace("[color=red]problem[/color]","",$num);

Okay I'm sure there's a beter  way of doing it, But thats how far my brain can think.

[code=php:0]
$nu = $num{5}.$num{6};
[/code]

Okay hehe my mistake!

The 13digit numer always change! But just need position 5 and 6's numbers

[trq]

My code will allways return positions 5 and 6.

Thanx Thorpe, just had to change the 5 to 4 and 6 to 5 to get position 5 and 6.
But working now.

Actually your code returns position 4 & 5, since position 0 (zero) is the first position.

Another way of doing it would be:
[code]<?php
$num = '1234567890123';
$num56 = substr($num,5,2);
echo $num56;
?>[/code]
