Question

所以我在这里尝试向客户端发送一些从javascript接收的数组文件。我的问题是我无法重新定义文件名（因为它的标题）。所以例如，我想发送3个文件到客户端，第一个发送，然后我得到了最后一个错误。有谁知道如何解决它？这是我的PHP代码：

PHP

<?php
ignore_user_abort(true);

set_time_limit(0); // disable the time limit for this script

$path = "../temp/"; // change the path to fit your websites document structure
$data = escapeshellarg($_GET['File']);
$data = str_replace("\\","",$data); // remove useless characters inserted 
$data = str_replace("\"","",$data); // 
$dl_file = explode(",", $data);

header("Content-type: application/octet-stream");
header("Cache-control: private"); //use this to open files directly
header('Pragma: private');

for($i = 0; $i < count($dl_file); $i++)
{
    $fullPath = $path.$dl_file[$i];
    $path_parts = pathinfo($fullPath);
    header("Content-Disposition: attachment; filename=\"".$path_parts["basename"]."\"",true);

    if ($fd = fopen ($fullPath, "r"))
    {
        $fsize = filesize($fullPath);
        $path_parts = pathinfo($fullPath);
        $ext = strtolower($path_parts["extension"]);

        ob_clean();
        flush();
        readfile($fullPath);
    }

    fclose ($fd);
}
exit;
?>

以下是我在服务器的日志文件中收到的错误：

Warning:  Cannot modify header information - headers already sent in (php file path)

从php服务器向客户端发送许多文件
