filemtime "warning stat failed for"
提问by Gerard Brull
I already read it so many questions and answers about it but I can't still solve my problem...
我已经阅读了很多关于它的问题和答案，但我仍然无法解决我的问题......
I'm trying to create a function that deletes all the files with "xml" or "xsl" extension that has been created one day ago. But I'm getting this warning on each file I have:
我正在尝试创建一个函数，用于删除一天前创建的所有带有“xml”或“xsl”扩展名的文件。但是我在我拥有的每个文件上都收到此警告：
Warning: filemtime() [function.filemtime]: stat failed for post_1003463425.xml in /home/u188867248/public_html/ampc/library.php on line 44
警告：filemtime() [function.filemtime]：第 44 行 /home/u188867248/public_html/ampc/library.php 中 post_1003463425.xml 的统计失败
All the files of this directory have the same structure name "post_ + randomNum + .xml" (example: post_1003463425.xml or post_1456463425.xsl). So I think it's not an encoded problem (like I saw in other questions).
该目录下的所有文件都具有相同的结构名称“post_ + randomNum + .xml”（例如：post_1003463425.xml 或 post_1456463425.xsl）。所以我认为这不是编码问题（就像我在其他问题中看到的那样）。
The code of my function is this:
我的函数代码是这样的：
function deleteOldFiles(){
if ($handle = opendir('./xml')) {
while (false !== ($file = readdir($handle))) {
if(preg_match("/^.*\.(xml|xsl)$/i", $file)){
$filelastmodified = filemtime($file);
if ( (time()-$filelastmodified ) > 24*3600){
unlink($file);
}
}
}
closedir($handle);
}
}
Thanks for your help :)
谢谢你的帮助 ：）

I think the problem is the realpath of the file. For example your script is working on './', your file is inside the directory './xml'. So better check if the file exists or not, before you get filemtime or unlink it:
我认为问题在于文件的真实路径。例如，您的脚本正在处理“./”，您的文件位于“./xml”目录中。因此，在获取 filemtime 或取消链接之前，最好检查文件是否存在：
function deleteOldFiles(){
if ($handle = opendir('./xml')) {
while (false !== ($file = readdir($handle))) {
if(preg_match("/^.*\.(xml|xsl)$/i", $file)){
$fpath = 'xml/'.$file;
if (file_exists($fpath)) {
$filelastmodified = filemtime($fpath);
if ( (time() - $filelastmodified ) > 24*3600){
unlink($fpath);
}
}
}
}
closedir($handle);
}
}

For me the filename involved was appended with a querystring, which this function didn't like.
对我来说，涉及的文件名附加了一个查询字符串，这个函数不喜欢。
$path = 'path/to/my/file.js?v=2'
Solution was to chop that off first:
解决方案是先把它砍掉：
$path = preg_replace('/\?v=[\d]+$/', '', $path);
$fileTime = filemtime($path);

Shorter version for those who like short code:
对于那些喜欢短代码的人来说更短的版本：
// usage: deleteOldFiles("./xml", "xml,xsl", 24 * 3600)
function deleteOldFiles($dir, $patterns = "*", int $timeout = 3600) {
// $dir is directory, $patterns is file types e.g. "txt,xls", $timeout is max age
foreach (glob($dir."/*"."{{$patterns}}",GLOB_BRACE) as $f) {
if (is_writable($f) && filemtime($f) < (time() - $timeout))
unlink($f);
}
}
