運行時我收到錯誤的項目：警告：執行opendir未能打開目錄：未實現

在index.php我有這樣的代碼：運行時我收到錯誤的項目：警告：執行opendir未能打開目錄：未實現

<?php 
$pattern="(\.jpg$)|(\.png$)|(\.jpeg$)|(\.gif$) |(\.Gif$)"; //valid image extensions 
$files = array(); 
$curimage=0; 
if($handle = opendir("http://newsxpressmedia.com/files/radar-simulation-files")) { 
    while(false !== ($file = readdir($handle))){ 
     if(eregi($pattern, $file)){ //if this file is a valid image 
      //Output it as a JavaScript array element 
      $files[] = $file; 
      $curimage++; 
     } 
    } 
    closedir($handle);

我的主人的網站是ipage.com 在上的iPage的文件管理器.com我從根目錄中看到目錄文件/ radar-simulation-files。

我正在使用netbeans 8.0.1和xampp來運行localhost apache服務器。

在NetBeans中，當我點擊運行按鈕，它會到此位置：

http://localhost/PhpProject2/index.php

還有，第一圖像上面我看到：

Warning: opendir(http://newsxpressmedia.com/files/radar-simulation-files): failed to open dir: not implemented in C:\xampp\htdocs\PhpProject2\index.php on line 5

我想要做的是讓目錄文件/雷達模擬文件中所有圖像的列表

編輯

這是我現在試圖代碼：

<?php 
$username = 'my domain name'; 
$password = 'my pass'; 
$basepath = 'domains/newsxpressmedia.com/public_html/'; 
$handle = opendir("ftp://{$username}:{$password}@ftp.ipage.com/{$basepath}files/radar-simulation-files"); 
//$imgdir = 'images/'; //Pick your folder 
$allowed_types = array('png','jpg','jpeg','gif'); //Allowed types of files 
//$dimg = opendir($imgdir);//Open directory 
while($imgfile = \readdir(handle)) 
{ 
    if(in_array(strtolower(substr($imgfile,-3)),$allowed_types) OR 
     in_array(strtolower(substr($imgfile,-4)),$allowed_types)) 
/*If the file is an image add it to the array*/ 
    {$a_img[] = $imgfile;} 
} 
echo "<ul>"; 

$totimg = count($a_img); //The total count of all the images 
//Echo out the images and their paths incased in an li. 
for($x=0; $x < $totimg; $x++){echo "<li><img src='" . $imgdir . $a_img[$x] . "' /></li>";} 
echo "</ul>"; 
?>

我已經將文件上傳到我的主機域名ipage.com文件管理然後我瀏覽到：

My site

它開始計數回定時器，但然後停止1

然後我在網站上做：檢查元件而在控制檯我看到錯誤：

遺漏的類型錯誤：無法讀取空

的特性「長度」上線23

某處有問題，PHP代碼，應該讓所有的圖像文件，並把它們在數組中。

現在編輯我的問題與我現在嘗試什麼，我得到什麼錯誤，我越來越。 – 2014-11-02 22:05:21

您不能使用opendir通過http瀏覽文件。相反，你應該嘗試ftp連接，如：

$username = 'ftp-username'; 
$password = 'ftp-password'; 
$basepath = 'domains/newsxpressmedia.com/public_html/'; 
$handle = opendir("ftp://{$username}:{$password}@ftp.ipage.com/{$basepath}files/radar-simulation-files")
