\b in PHP, available or not??

[shachi]

Hello all,
I am currently using PHP to(practice) manipulating files and I was wondering if I could use the "\b"(don't know what it is called) escaping character to simulate a backspace character in a text file?? I have been trying this for ages now and it is driving me knots. Any help would be greatly appreciated!! Thanks in advanced!!

Why would you want to?

Because I am having trouble with an extra newline character in my file.

Strip it then.

$lines = file('file.txt');
$lines[count($lines) - 1] = str_replace("\n", '', $lines[count($lines) - 1]);
$f = fopen('file.txt', 'w');
fwrite($f, implode('', $lines));
fclose($f);

So, isn't there any \b thing in PHP??

I don't think so, no. It doesn't really matter anyway, because it's a control character, it's not meant to be in text files.
