所以情况是WordPress通常安装在有限的权限或不完美配置的web主机上，并且不可能通过Php代码函数创建目录，复制或移动文件，或复制或移动整个目录到新位置。我有问题时:
rename(.., ..);given - 'do not have required permission'错误，CHMOD(..., 0777);也没有使目录可写，mkdir(..., 0777);没有在web用户下创建可写dirs，而是在apache用户(1000)下创建了0755 dirs，其中WordPress引擎的Php脚本无法写入。
我正在寻找一个最佳的工作解决方案(或工作区)复制所有文件从一个文件夹到另一个文件夹时，常规重命名(..)，chmod(..)和mkdir(..)Php函数没有按预期工作
所以我做了一个解决方案-一个类的工作，并提供了它的代码在这个主题的答案。我希望这会为你节省半天时间，就像现在为我节省半天时间一样。
我写了一个类来解决这个问题，我相信这将对你们中的许多人有所帮助，他们为WordPress开发插件，并且必须对文件进行操作。
用法示例如下:
$uploadDir = wp_upload_dir();
$fromFolder = ABSPATH."wp-content/plugins/old-cool-plugin/gallery"
$toFolder = $uploadDir['basedir']."/cool-plugin-gallery";
$copied = WordPressFileManager::copyFolder(fromFolder, $toFolder);
if($copied)
{
echo 'All old folder files copied successfully to new directory';
} else
{
echo 'Your server setup is so bad, that it is unbeatable even with perfect scripts';
}
类代码如下:
class WordPressFileManager
{
public static function createWritableDirectory($paramToFolderWithoutEndSlash)
{
// Create an upload dir if not exist
$newDirectoryExists = TRUE;
if (!file_exists($paramToFolderWithoutEndSlash))
{
// The mkdir doesn't work in WordPress setup on regular servers (DirectAdmin+Ubuntu based etc.)
//$uploadDirectoryExists = mkdir($paramToFolderWithoutEndSlash, 0777, TRUE);
$newDirectoryExists = wp_mkdir_p($paramToFolderWithoutEndSlash);
}
// Check if folder iss writable
$newDirectoryWritable = FALSE;
if($newDirectoryExists)
{
if(is_writable($paramToFolderWithoutEndSlash) === FALSE)
{
chmod($paramToFolderWithoutEndSlash, 0777);
if(is_writable($paramToFolderWithoutEndSlash))
{
$newDirectoryWritable = TRUE;
}
} else
{
$newDirectoryWritable = TRUE;
}
}
return $newDirectoryWritable;
}
/**
* Because copy($moveFolderAndAllFilesInsideFrom, $paramToFolder) - does NOT work in this WordPress setup (because of CHMOD rights),
* so we need a workaround function - and this is the main reason why we have a function bellow, which DOES WORK!
* @param $moveFolderAndAllFilesInsideFrom
* @param $paramToFolderWithoutEndSlash
*/
public static function recurseCopy($moveFolderAndAllFilesInsideFrom, $paramToFolderWithoutEndSlash)
{
$sourceDirectory = opendir($moveFolderAndAllFilesInsideFrom);
while (FALSE !== ( $file = readdir($sourceDirectory)) )
{
if (( $file != '.' ) && ( $file != '..' ))
{
if ( is_dir($moveFolderAndAllFilesInsideFrom.'/'.$file))
{
static::recurseCopy($moveFolderAndAllFilesInsideFrom.'/'.$file, $paramToFolderWithoutEndSlash.'/'.$file);
} else
{
copy($moveFolderAndAllFilesInsideFrom.'/'.$file, $paramToFolderWithoutEndSlash.'/'.$file);
}
}
}
closedir($sourceDirectory);
}
/**

public static function copyFolder($copyAllFilesFromFolderWithoutEndSlash, $paramToFolderWithoutEndSlash)
{
$copied = FALSE;
if(file_exists($copyAllFilesFromFolderWithoutEndSlash))
{
$toDirectoryIsWritable = static::createWritableDirectory($paramToFolderWithoutEndSlash);
if($toDirectoryIsWritable)

}

//echo "destination folder is writable: "; var_dump($toDirectoryIsWritable);
} else
{

return $copied;
