fscanf() until '\n' is reached?

[techniq]

I'm using fopen() on a file pointer (a unix FIFO named pipe to be exact). the data being read from the file pointer are single lines of data ending with '\n' on each line. I would like to fscanf() each line up to the '\n'. So far pieces of the code look like this, but I'm having problems knowing what the format should be in fscanf() in order to match the entire line up to the '\n'. The characters in each line could be anything including whitespace.

<?php

$fifo_file = "/tmp/php-alert.pipe";
$fp = fopen($fifo_file, "r");
$buffer = fscanf($fp, "%[^ ]\n");

?>

Thanks in advance.

I believe I resolved it. At least I'm now getting the results I want. And $buffer[0] contains each entire single line including the '\n'. The fscanf() looks like this now:

<?php

$fifo_file = "/tmp/php-alert.pipe";
$fp = fopen($fifo_file, "r");
$buffer = fscanf($fp, "%[^\t*]\n");

?>

Please correct me if I'm worng, but I think the "%[^\t*]" means any number of tabs. Which accorrding to the manual includes a single whitespace.

Thanks.
