writing to file including linefeed

[cloudbase]

Good morning everyone. I just started in php so please forgive my ignorance.
I'm trying to append $newflyline to a $flyline that contains $oldflyline then echo fgets($file). My problem is fgets is reading to the eof not the expected eol. Guess I'm missing the <lf> thing?
Here's what I have:

$flyline = 'testscript.txt';
		$oldflyline = file_get_contents($flyline);
		$newflyline = "new line<lf>";
//- - - open - write - close flyline - - - - - - - - - - - - - - - - - - - - - 
		$flockfile = fopen($flyline, 'w+') or exit('Unable to open file!');
	if (flock($flockfile, LOCK_EX)) {
			fwrite($flockfile, $newflyline);
			fwrite($flockfile, $oldflyline);
			flock($flockfile, LOCK_UN);} 
	else echo "oops! Try again, no lock on file";
				fclose($flockfile);
//- - - table display - - - - - - - - - -
	$file = fopen($flyline,'r') or exit('Unable to open file!');
	$i="1";
	while ($i <= 2){
		echo fgets($file); $i++; 
	}fclose($file);

This is what I'm getting running it 4 times;
new linenew linenew linenew line
what I want is to control the number of lines displayed with while($i<=2)
new line
new line
