获取文件大小用filesize函数
$size=filesize("../upload/a.txt");
function resize_bytes($size)
{
$count = 0;
$format = array("B","KB","MB","GB","TB","PB","EB","ZB","YB");
while(($size/1024)>1 && $count<8)
{
$size=$size/1024;
$count++;
}
$return = number_format($size,0,'','.')." ".$format[$count];
return $return;
}
直接使用：echo resize_bytes($size);
