PHP 请问怎么查看上传文件的大小？？

[muoubaby]

我做了一个网络硬盘的代码页面。。想要像如图那样显示出每一个上传的文件的大小。。

用filesize()怎么做？最好给出完整代码？？

<?php
$dirname = "./";

$str = "<table border=0 cellpadding='3' cellspacing='3' /><tr><td>文件名</td><td>大小</td></tr>";

$handler = opendir($dirname);
while(false !== ($entry = readdir($handler)))
{
	if($entry == "." || $entry == "..")
	{
		continue;
	}
	$str .= "<tr><td>".$entry."</td>";
	if(!is_dir($dirname.$entry))
	{
		$str .= "<td>".filesize($entry)."B</td></tr>";
	}
	else
	{
		$str .= "<td>_</td></tr>";
	}
	
}
closedir($handler);
$str .= "</table>";

echo $str;
?>

<?php
/**

function byteSizeConversion($size)
{
	//1024 b kb m g
	if($size <1024)
	{
		$s = $size."B";
	}
	elseif($size < 1024*1024)
	{
		$s = floor($size/1024)."K";
	}
	elseif($size < 1024*1024*1024)

Warning: filesize() [function.filesize]: stat failed for 2009783927.torrent in C:\htdocs\pp.php on line 66


按楼上的朋友给出的代码修改放上去后，出现了这样一条警告。。并且无法顺利显示出文件的大小。。怎么办呢？

66行代码是 $str .= "<td>".filesize($entry)."B</td></tr>";
