PHP文件下载计数器无效链接，原因是字符？

php

PHP文件下载计数器无效链接，原因是字符？,php,Php,我有一个脚本，我想编辑。 它基本上是下载文件并计数，然后按预期显示。唯一的问题是，当我使用包含字符的文件时，它会抛出无效文件错误，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（用于GG，KyleMorris&Murdo.zip）16的文件时，它会抛出一个无效文件错误 以下是我拥有的文件和代码： index.php download.php files folder

我有一个脚本，我想编辑。 它基本上是下载文件并计数，然后按预期显示。唯一的问题是，当我使用包含字符的文件时，它会抛出
无效文件
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（用于GG，KyleMorris&Murdo.zip）16的文件时，它会抛出一个
无效文件
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如下所示：


<?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;
}
?>

如果第二个是您遇到的问题，那么最后没有扩展。我不确定它是100%，但可能是一个可以查看的地方。是的，我相信这是我遇到问题的download.php。不抱歉，这个文件（GREGZYY-SUCK-it-AN-SEE-2O16.zip）最后有.zip，这个：（RyanJones-F.N.T（对于GG，KyleMorris&Murdo.zip）有16个。我也不确定括号的位置，但这可能是原因。哦，不，那只是因为我漏掉了它，它们都是zip文件，并且在我的文件上标记正确。我觉得这与utf字符集有关，但不是100%，我手头没有php开发环境，但如果今晚晚些时候无法解决这个问题，我会看一看。
