fwrite result PHP - php

Question

Im currently trying to write a few words on a file, and then open it.
currently, i do have the following outcome:
When my desired outcome would be something like:
How come it is like that?
TextAr is just some numbers from a textarea. ( one id each line)
code:
$text = preg_replace('/\n+/', "\n", trim($_POST['ids']));
$textAr = explode("\n", $text);
foreach ($textAr as $k=>$v) if(empty(trim($v))) unset($textAr[$k]);
$textAr = array_filter($textAr, 'trim');
$handle = fopen("file.txt", "w");
$saveresult = '';
foreach ($textAr as $line) {
$line = str_replace(' ', '', $line);
$line = preg_replace('/\D/', '', $line);
$result = httpPost($url, $line);
$showID = ($showID ? "".$result['id']." -" : '');
$notexisting = ($showasnull ? 0 : "N/A");
if ($result['manual'] == true) {
$saveresult .= "".$showID." Manual".PHP_EOL;
}
if ($result['hit'] == true && $result['manual'] != true) {
$saveresult .= "".$showID." " . $result['price'] . "".PHP_EOL;
} else if ($result['hit'] == false) {
$saveresult .= "".$showID." ".$notexisting."".PHP_EOL;
}
$saveresult .= "\r\n";
?>
<?PHP }
fwrite($handle, $saveresult);
fclose($handle);
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename('file.txt'));
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize('file.txt'));
readfile('file.txt');
EDIT
i removed $saveresult .= "\r\n"; but still same result.
EDIT 2:
example of textAr:
array(2) { [0]=> string(8) "43631132" [1]=> string(8) "43631132" }
example of $result
array(4) { ["id"]=> string(8) "43631132" ["price"]=> int(0) ["hit"]=> bool(false) ["manual"]=> bool(false) }

You can write each line independantly. This way you can check if the line itself is empty before writing.
foreach ($textAr as $line) {
$saveresult = "";
$line = str_replace(' ', '', $line);
$line = preg_replace('/\D/', '', $line);
$result = httpPost($url, $line);
$showID = ($showID ? "".$result['id']." -" : '');
$notexisting = ($showasnull ? 0 : "N/A");
if ($result['manual'] == true) {
$saveresult .= "".$showID." Manual";
}
if ($result['hit'] == true && $result['manual'] != true) {
$saveresult .= "".$showID." " . $result['price'];
} else if ($result['hit'] == false) {
$saveresult .= "".$showID." ".$notexisting;
}
$saveresult = trim($saveresult);
if (!empty($saveresult)) {
fwrite($handle, $saveresult.PHP_EOL);
}
}
fclose($handle);
