This article introduces a PHP code that implements formatted file size. The so-called formatted file size means that the file size in bytes is displayed in an easy-to-read manner, such as 120GB, 30MB, etc.
The code is as follows:
<?php
/**
* 格式化文件大小
* Edit bbs.it-home.org
*/
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];
}
?>Copy after login |
