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。
