通过PHP FTP上传整个目录

Question

我正在尝试编写一个脚本,通过ftp将存储在我服务器上的目录的全部内容上传到其他服务器.

我一直在阅读www.php.net上的文档,但似乎无法找到一次上传多个文件的方法.

有没有办法做到这一点,或者是否有一个脚本将索引该目录并创建要上载的文件数组？

在此先感谢您的帮助!

Answer 1

打开连接后,以串行方式上传目录的内容很简单:

foreach (glob("/directory/to/upload/*.*") as $filename)
    ftp_put($ftp_stream, basename($filename) , $filename, FTP_BINARY);

并行上传所有文件会更加困难.

Answer 2

所以,我拿了@ iYETER的代码,把它包装成一个类对象.

您可以通过以下行调用此代码:

$ftp = new FtpNew("hostname");

$ftpSession = $ftp->login("username", "password");

if (!$ftpSession) die("Failed to connect.");

$errorList = $ftp->send_recursive_directory("/local/dir/", "/remote/dir/");
print_r($errorList);

$ftp->disconnect();

它以递归方式抓取本地目录,并将其放在远程目录上.如果它遇到任何错误,它会创建每个文件的数组层次结构及其异常代码(到目前为止我只捕获2,如果是另一个错误,它现在抛出默认路由)

如果您想一次上传多个文件，则需要使用 thread 或 fork。

我不确定 PHP 中是否有线程实现，但您应该看看PHP SPL和/或PEAR

编辑：感谢 Frank Farmer 让我知道 PHP 中有一个 fork() 函数，称为pcntl_fork()

您还必须递归地获取整个内容目录，以便能够上传给定目录的所有文件。
