PHP and C # format the file size code separately

Source: Internet
Author: User
I found a method to format the file size. it is very handsome and concise. especially for PHP, only two lines of code are required for PHP:
The code is as follows:
Function format ($ size)
$ Sizetext = array ("B", "KB", "MB", "GB", "TB", "PB", "EB", "ZB ", "YB ");
Return round ($ size/pow (1024, ($ I = floor (log ($ size, 1024), 2). $ sizetext [$ I];

The code is as follows:
Public string formatSize (long size)
If (size = 0) return "0 ";
String [] sizetext = new string [] {"B", "KB", "MB", "GB", "TB", "PB "};
Int I = (int) Math. Floor (Math. Log (size, 1024 ));
Return Math. Round (size/Math. Pow (1024, I), 2). ToString () + sizetext [I];
