In addition, if you need to format the file byte size, the following method can be used for reference:
function byte_format($input, $dec=0)
{
$prefix_arr = array(' B', 'K', 'M', 'G', 'T');
$value = round($input, $dec);
$i=0;
while ($value>1024)
{
$value /= 1024;
$i++;
}
$return_str = round($value, $dec).$prefix_arr[$i];
return $return_str;
}
echo byte_format(2852662 37);
