将数组写入字符串并将文件发送到 PHP 下载

  • 772

我试图找出一个简单的问题。访问 url 时，需要对数据进行排序，在输出处获取一个字符串，将其写入文件并发送以供下载。该数组由对数据库的查询形成，然后迭代。结果是这样的结构

foreach ($allRes as $row){
    foreach ($row as $k => $v){
        if($k != 'section_id')
        {

            $str.= $v . $col_delimiter. '  -  ' . $count;
        }
    }
    $count++;
    $str .= $row_delimiter;
}

结果是带有连字符的行

我做到了，一切正常，但并非所有行都进入下载的文件

 header('Content-Disposition: attachment; filename="str.txt"');
 header('Content-Type: text/plain'); 
 header('Content-Length: ' . strlen($str));
 header('Connection: close');
 echo $str;

有人能遇到吗？

    Content-Length如果指定标题，则可以省略Content-Transfer-Encoding

    发送者不得在任何包含 Transfer-Encoding 头字段的消息中发送 Content-Length 头字段。RFC

    header('Content-Type: text/plain';
header('Content-Disposition: inline;filename="str.txt"');
header('Cache-Control: max-age=0');
header('Content-Transfer-Encoding: binary');

// If you're serving to IE, then the following may be needed
header('Cache-Control: max-age=1');

// If you're serving to IE over SSL, then the following may be needed
header ('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // Date in the past
header ('Last-Modified: ' . (new \DateTime('now'))->format('r'));
header ('Cache-Control: cache, must-revalidate'); // HTTP/1.1
header ('Pragma: public'); // HTTP/1.0
echo $str;
