A php function that counts directory file size, _PHP tutorial

A php function that counts the size of files in a directory.

I just arrived at the company this morning and my boss told me to hurry up and write a small function to count the size of files in a specified directory. I got it. Go ahead and do it, luckily you have a little basic knowledge and you’ll be done in a while, haha. The code is below.

2. /**
3. Function to count directory file size
4. @author xfcode
5. @link http://www.jbxue.com
6. */
7. function dirsize($dir)
8. {
9. 　@$dh = opendir($dir);
10. $size = 0;
11. 　while ($file = @readdir($dh))
12. 　{
13. 　if ($file != "." and $file != "..")
14. 　{
15. 　　$path = $dir."/".$file;
16. 　　if (is_dir($path))
17. 　　{
18. 　 $size = dirsize($path);
19. 　　}  
20. elseif (is_file($path))
21. 　　{
22. 　　$size = filesize($path);
23. 　　}  
24. 　}  
25. 　}
26. @closedir($dh);
27. 　return $size;
28. }
29. //functionend 
31. //eg:
32. $dir_path = "./my_files";
33. $dir_size = dirsize($dir_path);
34. $dir_size = $dir_size/1024/1024;
35. echo $dir_size."MB";
36. ?>

This function can recursively loop through all files in a directory and calculate the total file size in MB.
The newbie makes a move, and the bosses laugh.
