PHP - 在另一台服务器上的 opendir

发布于 2024-10-21 21:41:51 字数 125 浏览 5 评论 0原文

我对 PHP 有点陌生。

我有两个不同的主机，我希望其中一个主机中的 php 页面向我显示另一个主机的目录列表。我知道如何在同一主机上使用 opendir() 但是否可以使用它来访问另一台机器？

提前致谢

尝试：

<?php

$dir = opendir('ftp://user:[email protected]/path/to/dir/');

while (($file = readdir($dir)) !== false) {
    if ($file[0] != ".") $str .= "\t<li>$file</li>\n";
}

closedir($dir);

echo "<ul>\n$str</ul>";

Try:

<?php

$dir = opendir('ftp://user:[email protected]/path/to/dir/');

while (($file = readdir($dir)) !== false) {
    if ($file[0] != ".") $str .= "\t<li>$file</li>\n";
}

closedir($dir);

echo "<ul>\n$str</ul>";

您可以使用 PHP 的 FTP 功能远程连接到服务器并获取目录列表：

// set up basic connection
$conn_id = ftp_connect('otherserver.example.com'); 

// login with username and password
$login_result = ftp_login($conn_id, 'username', 'password'); 

// check connection
if ((!$conn_id) || (!$login_result)) { 
    echo "FTP connection has failed!";
    exit; 
}

// upload the file
$upload = ftp_put($conn_id, $destination_file, $source_file, FTP_BINARY); 

// check upload status
if (!$upload) { 
    echo "FTP upload has failed!";
} else {
    echo "Uploaded $source_file to $ftp_server as $destination_file";
}

// Retrieve directory listing
$files = ftp_nlist($conn_id, '/remote_dir');

// close the FTP stream 
ftp_close($conn_id);

You could use PHP's FTP Capabilities to remotely connect to the server and get a directory listing:

// set up basic connection
$conn_id = ftp_connect('otherserver.example.com'); 

// login with username and password
$login_result = ftp_login($conn_id, 'username', 'password'); 

// check connection
if ((!$conn_id) || (!$login_result)) { 
    echo "FTP connection has failed!";
    exit; 
}

// upload the file
$upload = ftp_put($conn_id, $destination_file, $source_file, FTP_BINARY); 

// check upload status
if (!$upload) { 
    echo "FTP upload has failed!";
} else {
    echo "Uploaded $source_file to $ftp_server as $destination_file";
}

// Retrieve directory listing
$files = ftp_nlist($conn_id, '/remote_dir');

// close the FTP stream 
ftp_close($conn_id);

我无法让 FTP 建议发挥作用，所以我采取了一种更非常规的路线，基本上是从“索引”页面中提取 html 并提取文件名。

索引页：

/files 的索引

父目录

提取码：

    $dir = "http://www.yoursite.com/files/";
    $contents = file_get_contents($dir);
    $lines = explode("\n", $contents);
    foreach($lines as $line) {
        if($line[1] == "l") { // matches the <li> tag and skips 'Parent Directory'
            $line = preg_replace('/<[^<]+?>/', '', $line); // removes tags, curtousy of http://stackoverflow.com/users/154877/marcel
            echo trim($line) . "\n";
        }
    }

I was unable to get the FTP suggestions to work so I took a more unconventional route, basically it yanks the html from the "Index of" page and extracts the filenames.

Index page:

Index of /files

Parent Directory

Extraction code:

    $dir = "http://www.yoursite.com/files/";
    $contents = file_get_contents($dir);
    $lines = explode("\n", $contents);
    foreach($lines as $line) {
        if($line[1] == "l") { // matches the <li> tag and skips 'Parent Directory'
            $line = preg_replace('/<[^<]+?>/', '', $line); // removes tags, curtousy of http://stackoverflow.com/users/154877/marcel
            echo trim($line) . "\n";
        }
    }
