如果$filename包含变音符号 (ä,ö,ü)file_get_contents($filename)在我的 Windows 操作系统上不起作用。通过反复试验，我发现我需要做file_get_contents(utf8_decode($filename))才能让它工作。

但是，当我将它实时推送到我的服务器时（猜想它是某种 Linux），它又返回了一个错误，所以我删除了utf8_decode它，突然它完美地工作了。

作为一种解决方法（所以我不需要在每次更改代码时手动更改这段代码）我已经尝试过

(mb_detect_encoding($filename, 'UTF-8', true)) ? utf8_decode$filename) : $filename;

因为这已经反过来解决了同样的问题（与 有同样的问题utf8_encode），但$filename结果证明在每个（服务器）环境中都是 UTF8 编码的，所以这不起作用，因为它总是正确的。

任何想法如何让它在两个系统上工作？（请不要“只迁移到 Linux 进行 PHP 开发”——我有 Linux，但出于多种原因我使用 Windows 的 ATM）

编辑：问题也出现了，fopen并且接受的解决方案也有效。

最好的方法是检测您是否使用 Windows 服务器。从中您可以应用正确的命令

if (strtoupper(substr(PHP_OS, 0, 3)) === 'WIN') {
    echo 'This is a server using Windows!';
} else {
    echo 'This is a server not using Windows!';
}

问题是对于不支持文件名或目录名的 UTF-8 但 Linux 在 php 6 中支持 UTF-8 的窗口文件系统，这个问题解决了，为了在当前版本的 php 中解决这个问题，我们可以做一些工作，例如：

1) window 支持 UTF-16 和 linux 对这种 Unicode 没有任何问题 我们可以用这种 Unicode 保存所有文件名和目录名

2)编码 UTF-8 的urlencode ，这是解决此问题的另一种方法，我建议使用此方法。

我写了这个脚本来解决这个问题测试它。

 function GetExt($sFileName)//ffilter
 {
     $sExt="";
     $sTmp=$sFileName;
     while($sTmp!="")
     {
        $sTmp=strstr($sTmp,".");
        if($sTmp!="")
        {
            $sTmp=substr($sTmp,1);
            $sExt=$sTmp;
        }
     }
     return ($sExt);
 }
  function LocatePath($Path='/',$Mode="rb",$Root="",$Open=true,$IsFile=false){//make real Path and create new Directory

            $Read=true;
            $Write=false;

 }

样本：

如果目录或文件不存在，则打开文件进行写入和读取创建它。1)

 print_r(LocatePath('/er/ert/aیgfسبd/ی.af',"w+"));

返回一些信息，例如 fopen 的句柄

输出

Array
(
[ISDir] => 
[Handle] => Resource id #3
[Path] => F:/xampp/htdocs/er/ert/a%DB%8Cgf%D8%B3%D8%A8d/%DB%8C.af
[FileName] => ی.af
[Type] => af
[Create] => 1
[RelativePath] => er/ert/aیgfسبd/ی.af
[ParentDir] => er/ert/aیgfسبd
[Read] => 1
[Write] => 1
)

2) 打开文件进行读取，如果不存在则返回 false

 print_r(LocatePath('/er/ert/aیgfسبd/ی.af',"rb"));

以及与 fopen 相同的另一种模式
