在php中以编程方式将文件从一台服务器复制到另一台服务器

我在一台服务器上托管了我所有的代码文件，它的域类似于

example.com

，我现在就在其中一个html页面上。我希望example.com的一些文件移动到另一台服务器上，该服务器的域类似于

example2.com

。我在网上搜索过，但找不到好的解决办法。请告诉我，这是没有FTP客户端或没有浏览器，我们手动上传文件可能。或者有没有什么方法可以像我们要写的那样，从一个服务器向另一个服务器提交HTML表单中的文件

<form action="http://example2.com/action_page.php">

---

如果您将此文件的内容：example2.com/action\u page.php设置为：

<?php
$tobecopied = 'http://www.example.com/index.html';
$target = $_SERVER['DOCUMENT_ROOT'] . '/contentsofexample/index.html';

if (copy($tobecopied, $target)) {
    //File copied successfully
}else{
    //File could not be copied
}
?>

并通过命令行或cron运行它（正如您编写了一个与php相关的问题，但禁止使用浏览器！），它应该将example.com/index.html的内容复制到名为contentsofexample的站点目录（域：example2.com）中

---

N.B.如果你想复制整个网站，你应该把它放在for循环中

还有两种可能的方法可以用来从另一台服务器复制文件

-一种是从example.com中删除.htaccess文件，或者允许访问所有文件（通过修改.htaccess文件）。 -通过各自的URL访问/读取这些文件，并使用“file\u get\u contents（）”和“file\u put\u contents（）”方法保存这些文件。但这种方法也将使其他人可以访问所有文件

            $fileName       = 'filename.extension';
            $sourceFile     = 'http://example.com/path-to-source-folder/' . $fileName;
            $targetLocation = dirname( __FILE__ ) . 'relative-path-destination-folder/' + $fileName;

            saveFileByUrl($sourceFile, $targetLocation);

            function saveFileByUrl ( $source, $destination ) {
                if (function_exists('curl_version')) {
                    $curl   = curl_init($fileName);
                    $fp     = fopen($destination, 'wb');
                    curl_setopt($ch, CURLOPT_FILE, $fp);
                    curl_setopt($ch, CURLOPT_HEADER, 0);
                    curl_exec($ch);
                    curl_close($ch);
                    fclose($fp);
                } else {
                    file_put_contents($destination, file_get_contents($source));
                }
            }

或者，您可以在example.com上创建一个代理/服务，以便在验证密钥或用户名/密码组合后读取特定文件（根据您的要求）

---

您可以通过url“”访问该代理/服务。

您也可以使用zip方法在服务器之间交换文件。 您拥有这两台服务器，因此不应出现安全问题

在托管所需文件或文件夹的服务器上，创建一个php脚本并为其创建一个cron作业。示例代码如下：

<?php
/**
 * ZIP All content of current folder

/* ZIP File name and path */
$zip_file = 'myfiles.zip';

/* Exclude Files */
$exclude_files = array();
$exclude_files[] = realpath( $zip_file );
$exclude_files[] = realpath( 'somerandomzip.php' );

/* Path of current folder, need empty or null param for current folder */
$root_path = realpath( '' ); //or $root_path = realpath( 'folder_name' ); if the file(s) are in a particular folder residing in the root

/* Initialize archive object */
$zip = new ZipArchive;
$zip_open = $zip->open( $zip_file, ZipArchive::CREATE );

/* Create recursive files list */
$files = new RecursiveIteratorIterator(
    new RecursiveDirectoryIterator( $root_path ),
    RecursiveIteratorIterator::LEAVES_ONLY
);

/* For each files, get each path and add it in zip */
if( !empty( $files ) ){

    foreach( $files as $name => $file ) {

        /* get path of the file */
        $file_path = $file->getRealPath();

        /* only if it's a file and not directory, and not excluded. */
        if( !is_dir( $file_path ) && !in_array( $file_path, $exclude_files ) ){

            /* get relative path */
            $file_relative_path = str_replace( $root_path, '', $file_path );

            /* Add file to zip archive */
            $zip_addfile = $zip->addFile( $file_path, $file_relative_path );
        }
    }
}
/* Create ZIP after closing the object. */
$zip_close = $zip->close();
?>

瞧

FTP有什么问题？@Dai我想自动完成。不是手动的：）
