本文实例讲述了php计算整个目录大小的方法。分享给大家供大家参考。具体实现方法如下：
/** * calculate the full size of a directory * * @author jonas john * @version 0.2 * @param string $directorypath directory path */function calcdirectorysize($directorypath) { // i reccomend using a normalize_path function here // to make sure $directorypath contains an ending slash // to display a good looking size you can use a readable_filesize // function. $size = 0; $dir = opendir($directorypath); if (!$dir) return -1; while (($file = readdir($dir)) !== false) { // skip file pointers if ($file[0] == '.') continue; // go recursive down, or add the file size if (is_dir($directorypath . $file)) $size += calcdirectorysize($directorypath . $file . directory_separator); else $size += filesize($directorypath . $file); } closedir($dir); return $size;}//使用范例：$sizeinbytes = calcdirectorysize('data/');
希望本文所述对大家的php程序设计有所帮助。
