I'm improving the graphics on my RPG. Instead of having some text say "You slash the Wolf with your TinSword, doing 6 damage." i want it to show an image of of a slash mark and the number 6. Which i can do easy.

Problem comes when the numbers reach double figures. I'm not going to make 9999 images, one for each ammout of damage that can be done. Instead i just want to make 0-9 then then put them next to each other, so that i have my 1.gif next to 3.gif to make it look like 13.

What do i put in php to make this happen?

For two-digit numbers, just use floor($value / 10) and $value % 10.

For longer numbers, one way off the top of my head would be

<?php
$value = 135125; // $value is your number
$value = (string)$value;
for ($i = 0; $i < strlen($value); $i++)
 print $value[$i] . '<br />'; 
?>

DCoder, Thanks

<?php
$value = 135125;
$value = (string)$value;
echo ("<img src=".$value{0}.".gif>");
echo ("<img src=".$value{1}.".gif>");
echo ("<img src=".$value{2}.".gif>");
echo ("<img src=".$value{3}.".gif>");
echo ("<img src=".$value{4}.".gif>");
?>

Now i have everything i need to make my interface look like FF

I'd use gd library.

GD aint as hard as you'd think, more and more people use it by the day since its just really really useful. All you have to do is know the functions - thats what php is all about.
