And the reason I used this is that I'm manually copying every converted char to a single array element. If using str_to_num, I'd have to make a 2-element array, and just read the first one, and call a native and go all the way back to the VM again.

EDIT: A little optimization if you guys prefere it:

PHP Code:

num_to_char(num)
{
    if(num < 0 || num > 9)
        return '^0'

    return('0' + num)
}

char_to_num(char)
{
    if(char < '0' || char > '9')
        return 0
    
    return (char - '0')
}
