The issue isn't that I can't get colours to display on the screen, if I
were to substitute
$pstring = $connections[$channel][2] . $connections[$channel][1] . " " .
$buffer . chr(7);
for
$pstring = "\033[33m" . $connections[$channel][1] . " " .
$buffer . chr(7);
then it would work perfectly.
Thanks again,
Luke Slater

Hi,
I'm storing ANSI escape sequences in an array, stored like this:
$connections[$channel][2] = $info['colour'];
$info['$colour'] would contain something like \033[33m
Now, my problem is when I try and print it:
$pstring = $connections[$channel][2] . $connections[$channel][1] . " " .
$buffer . chr(7);
It will print as a literal string, actually printing \033[33m to the
screen, so how do I make it work?
I'm sure I'm missing something fatally simple here.
Thanks for your help,

What you're storing is human shorthand for bytes sent to the display.
(I'm assuming you're working with the terminal here, not a browser
window.) The \033 indicates an octal byte with that value. But when you
send it, you're sending each character individually to the screeen. That
is '\' is one byte, '0' is the next, '3' the next, etc. That '\033' (and
subsequent codes) need to be coded as single bytes and sent bytewise to
the terminal. And if your terminal isn't configured to accept ANSI
excape codes, it won't work anyway.
Your chr(7) is the clue. Your codes, if numeric, need to be converted to
integers and given to the chr() function, and output using that
function. Try converting some known codes into integers, outputting them
via the chr() function, and seeing if the result is what you expected.
You may need to use the inverse function, ord(), to get your codes into
numeric form. For example, ord('m') will return decimal 109. That's only
an example, since you should be able to send single characters to the
terminal as is.

Hi,
Interesting and so easy solution, last time I tried it I had to
re-initialize my console!! It sure works better and is also much more
secured. I'll give it a try on bsd and solaris consoles too (still
doesn't work on cygwin)
