本文实例讲述了php计算指定目录下文件占用空间的方法。分享给大家供大家参考。具体分析如下:

php中可以通过 RecursiveDirectoryIterator 扩展 DirectoryIterator的getChildren() 方法提供访问子目录中的每一个元素的方法,下面的代码通过遍历访问目录下的所有文件,获取他们暂用的空间。

<&#63;php
$dir = new RecursiveDirectoryIterator('C:\wamp');
$totalSize = 0;
foreach (new RecursiveIteratorIterator($dir) as $file) {
  $totalSize += $file->getSize();
}
print "The total size is $totalSize.\n";
&#63;>
Copy after login

希望本文所述对大家的php程序设计有所帮助。
