plaintext函数：递归设置权限参数：路径 path，文件权限 filePerm（默认0644），目录权限 dirPerm（默认0755）功能：检查路径是否存在，如果不存在则返回FALSE；如果是文件，则设置文件权限；如果是目录，则递归设置目录权限。

<? function recursiveChmod($path, $filePerm=0644, $dirPerm=0755) { // Check if the path exists if(!file_exists($path)) { return(FALSE); } // See whether this is a file if(is_file($path)) { // Chmod the file with our given filepermissions chmod($path, $filePerm); // If this is a directory... } elseif(is_dir($path)) { // Then get an array of the contents $foldersAndFiles = scandir($path); // Remove "." and ".." from the list $entries = array_slice($foldersAndFiles, 2); // Parse every result... foreach($entries as $entry) { // And call this function again recursively, with the same permissions recursiveChmod($path."/".$entry, $filePerm, $dirPerm); } // When we are done with the contents of the directory, we chmod the directory itself chmod($path, $dirPerm); } // Everything seemed to work out well, return TRUE return(TRUE); } ?>
