PHP - 获取目录的大小 [英] PHP – get the size of a directory

问题描述

在PHP中获取目录大小的最佳方法是什么？我正在寻找一个轻量级的方式来做到这一点，因为我将使用这个目录是相当巨大的。
$ b

已经有一个 fopen / code>因为安全原因被禁用。） .php.net / manual / en / class.recursivedireiteite.phprel =noreferrer> RecursiveDirectoryIterator 可以使用吗？

  $ bytes = 0; 
 $ iterator = new RecursiveIteratorIterator（new RecursiveDirectoryIterator（$ dir））; 
 foreach（$ iterator as $ i）
 {
 $ bytes + = $ i-> getSize（）; 
} 
  

What is the best way to get the size of a directory in PHP? I'm looking for a lightweight way to do this since the directories I'll use this for are pretty huge.

There already was a question about this on SO, but it's three years old and the solutions are outdated.(Nowadays fopen is disabled for security reasons.)

解决方案

Is the RecursiveDirectoryIterator available to you?

$bytes = 0;
$iterator = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($dir));
foreach ($iterator as $i) 
{
  $bytes += $i->getSize();
}
