filemtime() [function.filemtime]: stat failed for filenames with umlauts
提问by Benny Neugebauer
I use the PHP function filemtimeto get the last modification time with PHP 5.3. This functions works very well but it seems to have some problems when the filenames have special characters (for example umlauts).
我使用 PHP 函数filemtime来获取 PHP 5.3 的最后修改时间。此函数运行良好，但当文件名包含特殊字符（例如元音变音）时，它似乎会出现一些问题。
If I run it on a filename with umlauts
如果我在带有变音符号的文件名上运行它
$stat = filemtime('C:/pictures/München.JPG');
then I get the output:
然后我得到输出：
Warning: filemtime() [function.filemtime]: stat failed for C:/pictures/München.JPG
If I rename the file from "München.JPG" to "Muenchen.JPG" and do the same thing again:
如果我将文件从“München.JPG”重命名为“Muenchen.JPG”并再次执行相同的操作：
$stat = filemtime('C:/pictures/Muenchen.JPG');
everything works fine!
一切正常！
My PHP file is saved as UTF-8 without BOM and I also tried:
我的 PHP 文件保存为没有 BOM 的 UTF-8，我也尝试过：
clearstatcache();
$stat = filemtime(utf8_encode('C:/pictures/München.JPG'));
but it has not helped.
但它没有帮助。

With the following code snippet I found out that the file encoding on Windows 7 is "ISO-8859-1":
通过以下代码片段，我发现 Windows 7 上的文件编码为“ISO-8859-1”：
$scandir = scandir('.')
$encoding = mb_detect_encoding($scandir[0], 'ISO-8859-1, UTF-8, ASCII');
echo $encoding;
I've read that utf8_decodeconverts a UTF-8 string to ISO-8859-1 so I ended up with this small code that works for my project:
我读过utf8_decode将 UTF-8 字符串转换为 ISO-8859-1 所以我最终得到了这个适用于我的项目的小代码：
$file = 'C:/pictures/München.JPG';
$lastModified = @filemtime($file);
if($lastModified == NULL)
$lastModified = filemtime(utf8_decode($file));
echo $lastModified;
Thank you to all who have submitted a comment. You have steered me in the right direction. :-)

try this
尝试这个
$dir = 'uploads/';
if (is_dir($dir)) { if ($dh = opendir($dir)) {
while (($file = readdir($dh)) !== false) {
clearstatcache();
if(is_file($dir."/".$file)) {
echo $file;
echo " - ";
echo "Last modified: " . date ("F d, Y H:i:s.", filemtime(utf8_decode($dir."/".$file)));
echo "<br>";
}
}
echo "<br>";
closedir($dh);
}
}
