Opendir错误;找不到这样的文件或目录 [英] Opendir error; No such file or directory found

问题描述

这可能是一个非常简单的问题。我在目录/手机上工作，我在目录/上传中有照片。

This may be a very easy question. I am working in directory /mobile and I have photos in a directory /uploads.

我收到错误：

警告：opendir（http://www.yoozpaper.com/uploads）[function.opendir]：无法打开目录：未在/ hermes / bosweb / web088 / b881 / ipg中实现。第313行的yoozpapercom / mobile / sportspage.php

我把它放入变量$ dir = http ：//www.yoozpaper.com/uploads

I am putting this into a variable $dir = "http://www.yoozpaper.com/uploads"

图片 src = $ dir / $ file 。

请注意，当我处理主目录中的文件时，这是有效的。

Note that this is working when I am working with files in the main directory.

对此的任何帮助将不胜感激。

Any help on this would be greatly appreciated.

以下代码：

$dir = "http://www.yoozpaper.com/uploads";

//打开目录

if ($opendir = opendir($dir))
{

//读取目录

while (($file = readdir($opendir)) !==FALSE)
{

if ($file==$imagename)

//可以指定下面的高度和宽度

//can specify height and width below

echo "<img width='75%' height='30%' src='$dir/$file' title='$headline - Yoozpaper News Online' alt='$headline'><br /><br />";

推荐答案

您必须了解 a之间的区别文件系统和 HTTP守护程序。

虽然外观有些相似，但绝对不同。

You have to understand the difference between a filesystem and an HTTP daemon.
Although they have somewhat similar appearance, it is absolutely different matters.

要使用opendir，您必须打开* 目录，而不是HTTP资源。

To use opendir, you have to open *a directory, not HTTP resource.

opendir('../uploads');

应该有效

opendir($_SERVER['DOCUMENT_ROOT'].'/uploads');

会更好，因为它总是指向uploads目录，无论你从哪里调用它。

would be better as it will always point to the uploads directory, no matter from where you called it.
