PHP遍历目录并返回统计目录大小

分享一个 PHP并返回统计目录大小的方法。

代码：

php $dirname = "test1"; //mkdir($dirname);

 //遍历一层目录  function listdir($dirname) { $ds = opendir($dirname); while($file = readdir($ds)) { $path = $dirname.'/'.$file; if(is_dir($file)) { echo "DIR:".$file."
"; if($file != "." && $file != "..") { 
listdir($file); 
} 
} else { echo "FILE:".$file . "
"; 
} 
} 
} function totdir($dirname) { //对listdir稍加修改  static $tot = 0; $ds = opendir($dirname); while($file = readdir($ds)) { $path = $dirname.'/'.$file; if(is_dir($file)) { //echo "DIR:".$file."
";  if($file != "." && $file != "..") { $tot += totdir($file); 
} 
} www.jbxue.com else { //echo "FILE:".$file . "
";  $tot += filesize($path); 
} 
} //返回总计  return $tot; 
}

listdir($dirname); echo totdir($dirname)." bytes"; ?>
