I have written this function to rewrite the contents of a text file
after it's been updated. I store lines of data in an array and then
implode them into one string. The problem is that I'm getting an extra
line break (in other words a blank line is showing up in my text file)
after I modify a particular line. I checked the imploded string with
var_dump and don't see any line breaks besides the ones that separate
each line. Anyone have any ideas as to why I'm getting an extra line
break? The function is below with the code that calls it below that.

// Rewrite data file from array of file lines
function rewrite_file($lines) {
$filecontents = implode("\n", $lines);
$fh = fopen("data.txt", "w") or die("Could not open file.");
flock($fh, LOCK_EX);
if (fwrite($fh, $filecontents) == -1) {
die("File could not be written to.");
}
ftruncate($fh, ftell($fh)) or die("Error.");
flock($fh, LOCK_UN);
fclose($fh) or die("Error.");
}
