Actually, there appears to be a solution on the PHP.web
[http://www.php.net/manual/en/function.fgets.php]
"Note: The length parameter became optional in PHP 4.2.0, if omitted, it would
assume 1024 as the line length. As of PHP 4.3, omitting length will keep reading
from the stream until it reaches the end of the line. If the majority of the
lines in the file are all larger than 8KB, it is more resource efficient for
your script to specify the maximum line length. "
Thanks :-)
