自学php 有个小问题 求高手
  test.php
//echo filesize("http://localhost:81/qq.jpg/");
echo filesize("E:/Apache/htdocs/qq.jpg/");
?>
这个filesize函数咋么这么爱报warning,
Warning: filesize() [function.filesize]: stat failed for E:/Apache/htdocs/qq.jpg/ in E:\Apache\htdocs\test.php on line 4

apache  路径没问题 到底那里错了
------解决思路----------------------
filesize("E:/Apache/htdocs/qq.jpg/");
最后的 ‘/’ 是什么意思
