文件大小显示，例如 1.7K ， 2.9M
代码如下：
代码如下:
// A much better and accurate version can be found
// in Aidan's PHP Repository:

/**
* Returns a human readable filesize

*/
function HumanReadableFilesize($size) {
// Adapted from: http://www.php.net/manual/en/function.filesize.php
$mod = 1024;
$units = explode(' ','B KB MB GB TB PB');
for ($i = 0; $size > $mod; $i++) {
$size /= $mod;
}
return round($size, 2) . ' ' . $units[$i];
}
