Question about code

[AnhTuanCool]

Hi,

Have anyone heard about cdom(i don't know exactly), but when we put cdom is a function like function get_array(cdom, array_x) and cdom will be a number, when it gets into function, it becomes a letter, part of that function, such as 81 stands for the letter Q, 80 stands for P, 70 stands for F? Is it a kind of abbreviation or encoding, and what is the full chart of all letters? (those letter I gave above are I unintentional picked up) :ermm:

It seems you're asking how to convert an ASCII value to its corresponding character, and vice versa. The two functions are http://www.php.net/chr and http://www.php.net/ord , respectively.
