Question

我有一个我想编辑的脚本。它基本上下载文件并对其进行计数，然后按预期显示它。唯一的问题是，当我使用包含字符的文件时，会抛出invalid file错误而不是下载。

例如，当我有一个名为（GREGZYY-SUCK-iT-AN-SEE-2O16.zip）的文件时，它会下载该文件。但是，当我有一个名为（RyanJones - F.N.T（For GG，KyleMorris＆amp; Murdo.zip）16）的文件时，它会引发invalid file错误。

以下是我拥有的文件和代码：

index.php
download.php
files folder & a counters folder

index.php如下：

<?php 
function get_download_count($file=null){
$counters = './counters/';
if($file == null) return 0;
$count = 0;
if(file_exists($counters.md5($file).'_counter.txt')){
    $fp = fopen($counters.md5($file).'_counter.txt', "r");
    $count = fread($fp, 1024);
    fclose($fp);
}else{
    $fp = fopen($counters.md5($file).'_counter.txt', "w+");
    fwrite($fp, $count);
    fclose($fp);
}
return $count;
}
?>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

<body>

<a href="./download.php?file=filenameziphere.zip">filenameziphere</a>     (Downloaded <?php echo get_download_count('filenameziphere.zip');?> times)    <br>
<a href="./download.php?file=filenameziphere2.zip">filenamehere</a> (Downloaded <?php echo get_download_count('filenameziphere2.zip');?> times)    <br>

</body>
</html>

download.php如下：

<?php 

$downloads_folder = './';
$counters_folder = './counters/';

if(!empty($_GET['file'])){
$file = basename($_GET['file']);

if(file_exists($downloads_folder.$file)){

    if(file_exists($counters_folder.md5($file).'_counter.txt')){
        $fp = fopen($counters_folder.md5($file).'_counter.txt', "r");
        $count = fread($fp, 1024);
        fclose($fp);
        $fp = fopen($counters_folder.md5($file).'_counter.txt', "w");
        fwrite($fp, $count + 1);
        fclose($fp);
    }else{
        $fp = fopen($counters_folder.md5($file).'_counter.txt', "w+");
        fwrite($fp, 1);
        fclose($fp);
    }

header('Content-Description: File Transfer');
    header('Content-Type: application/octet-stream');
    header('Content-Disposition: attachment; filename="'.$file.'"');
    header('Content-Transfer-Encoding: binary');
    header('Connection: Keep-Alive');
    header('Expires: 0');
    header('Cache-Control: must-revalidate, post-check=0, pre-    check=0');
    header('Pragma: public');
    header('Content-Length: ' . sprintf("%u",     filesize($downloads_folder.$file)));

// http headers for zip downloads
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: public");
header("Content-Description: File Transfer");
header("Content-type: application/octet-stream");
header("Content-Disposition: attachment; filename=\"".$file."\"");
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".sprintf($downloads_folder.$file));
ob_end_flush();

    $fh = fopen($downloads_folder.$file, "rb");
    while (!feof($fh)) {
        echo fgets($fh);
        flush();
    }
    fclose($fh);
    exit;
}else{
    header("HTTP/1.0 404 Not Found");
    exit('File not found!');
}
}
?>

我尝试有时将utf charset更改为utf-8和其他部分，但仍然没有任何效果。任何帮助表示赞赏，如果可能的话，还需要更短的代码。

PHP文件下载计数器由于字符无效链接？
