这可能是之前被问到的,我是
PHP的新手,我正在努力学习尽可能多的东西,但这真的让我失望了.
基本上我想知道的是,我如何使用PHP代码将其从远程服务器下载到本地位置.它正在下载所有不仅仅是我坚持的文件.那么请有人向我展示/解释我将如何做到这一点？
提前致谢.
到目前为止我得到了什么
@H_502_7@<?PHP $connection - ssh2_connect('example.com',22); ssh2_auth_password($connection,'username','password'); $remote_dir="/remote_dir/"; $local_dir="/local_dir/"; $remote ="$remote_dir"; $stream = ssh2_exec($connection,$remote); stream_set_blocking($stream,true); $command=fread($stream,4096); $array=explode(\n,$command); $total_files=sizeof($array); for($i=0;$i<$total_files;$i+++){ $file_name=trim($array[$i]); if($file_name!=''{ $remote_file=$remote_dir.$file_name; $local_file=$local_dir.$file_name; if(ssh2_scp_recv($connection,$remote_file,$local_file)){ echo "File ".$file_name." was copied to $local_dir<br />"; } } } fclose($stream); ?>我想我的$remote =“$remote_dir”;是错的,说实话,当我想要整个目录时,我有$filename,这是我到目前为止所有的.
这是一个关于如何读取文件夹并下载其所有文件的小代码：
@H_502_7@<?PHP
$host = 'localhost';
$port = 22;
$username = 'username';
$password = 'password';
$remoteDir = '/must/be/the/complete/folder/path';
$localDir = '/can/be/the/relative/or/absolute/local/path';
if (!function_exists("ssh2_connect"))
die('Function ssh2_connect not found,you cannot use ssh2 here');
if (!$connection = ssh2_connect($host,$port))
die('Unable to connect');
if (!ssh2_auth_password($connection,$username,$password))
die('Unable to authenticate.');
if (!$stream = ssh2_sftp($connection))
die('Unable to create a stream.');
if (!$dir = opendir("ssh2.sftp://{$stream}{$remoteDir}"))
die('Could not open the directory');
$files = array();
while (false !== ($file = readdir($dir)))
{
if ($file == "." || $file == "..")
continue;
$files[] = $file;
}
foreach ($files as $file)
{
echo "Copying file: $file\n";
if (!$remote = @fopen("ssh2.sftp://{$stream}/{$remoteDir}{$file}",'r'))
{
echo "Unable to open remote file: $file\n";
continue;
}
if (!$local = @fopen($localDir . $file,'w'))
{
echo "Unable to create local file: $file\n";
continue;
}
$read = 0;
$filesize = filesize("ssh2.sftp://{$stream}/{$remoteDir}{$file}");
while ($read < $filesize && ($buffer = fread($remote,$filesize - $read)))
{
$read += strlen($buffer);
if (fwrite($local,$buffer) === FALSE)
{
echo "Unable to write to local file: $file\n";
break;
}
}
fclose($local);
fclose($remote);
}
您也可以恢复此代码(它不会复制目录)：
@H_502_7@while (false !== ($file = readdir($dirHandle))) { if ($file == "." || $file == "..") continue; echo "Copying file: $file\n"; if(!ssh2_scp_recv($connection,$remoteDir . $file,$localDir . $file)) echo "Could not download: ",$remoteDir,$file,"\n"; }如果您不使用远程文件夹上的完整路径,它将无法工作：
@H_502_7@opendir("ssh2.sftp://{$stream}{$remoteDir}")
