I have this code, By my thoughts, each entry should go onto a new line, but apparently not by PHP's thinking :p It is all on one continous line
$email2 = $email;
$email2 .="\n";
$filename = "../emailcheck.txt";
$handle = fopen($filename, "r");
$old_content = fread($handle, filesize ($filename));
$handle = null;
$newcontent = $email2.$old_content;
$handle2 = fopen($filename, "w");
$finalwrite = fwrite($handle2, $newcontent);
fclose($handle2);
