fwrite结果PHP

Question

我现在试着在一个文件上写几个字，然后打开它。

目前，我确实取得了以下成果：

​

​

当我想要的结果是：

​

怎么会是这样？

TextAr只是来自文本区域的一些数字。(每一行一个id )代码：

 $text = preg_replace('/\n+/', "\n", trim($_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');

编辑

我删除了$saveresult .= "\r\n";，但结果仍然相同。

textAr的例子：

array(2) { [0]=> string(8) "43631132" [1]=> string(8) "43631132" }

$result实例

array(4) { ["id"]=> string(8) "43631132" ["price"]=> int(0) ["hit"]=> bool(false) ["manual"]=> bool(false) }

你可以独立地写每一行。这样，您就可以在写之前检查行本身是否为空。

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);
