File exists and you have to append, or you have full file content and then you want append and save? — robertw, Jun 09 '14 at 08:50

Alternatively, you could use file(), and outputs an array. From there you can determine the second to the last line. Consider this example:

$replacement = "Hello World";
$contents = file('file.txt', FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES);
$size = count($contents);
$contents[$size-2] = $replacement; // point it to the second last line and assign
$temp = implode("\n", $contents);
file_put_contents('file.txt', $temp);

file put contents append before last second line
