【问题描述】：

这是我的 php 脚本，当我扫描目录并将其存储在数组中时，我正在尝试使用 SSH 将照片上传到其他服务器。

然后我尝试在终端中运行直到索引 9 正确上传，当索引到达 10 时出现问题.......................... ..................................................... ..................................................... ......

$username = 'root';
$password = 'Workflow#5992$';

$connection = ssh2_connect($host, 22);


ssh2_auth_password($connection, $username, $password);

$sftp = ssh2_sftp($connection);



// Specifying directory
$mydir = '/var/www/html/AcadWFReport/photos';

// Scanning files in a given directory in ascending order
$myfiles = scandir($mydir);

// Displaying the files in the directory
print_r($myfiles);


$c = count($myfiles);
//print_r($c);

for ($i = 2; $i < $c; $i++){    
$fname= substr($myfiles[$i],0,8); 
$ext= substr($myfiles[$i],9,3);
$b= substr($myfiles[$i],2,2);
$batch=20 . $b ;
$pid= substr($myfiles[$i],4,1);
$pname=$myfiles[$i];

$result1=ssh2_sftp_mkdir($sftp, '/var/www/html/Dev/File_upload/doc/byroll/'.$batch.'');
$result2=ssh2_sftp_mkdir($sftp, '/var/www/html/Dev/File_upload/doc/byroll/'.$batch.'/'.$pid.'');

$local_file = '/var/www/html/AcadWFReport/photos/'.$pname.'';
$remote_file = '/var/www/html/Dev/File_upload/doc/byroll/'.$batch.'/'.$pid.'/'.$pname.'';






echo 'Uploading...'.$pname.''.$i.''."\n";

$stream = file_exists("ssh2.sftp://$connection/var/www/html/Dev/File_upload/doc/byroll/".$batch."/".$pid."/".$pname."");
if($stream){
    
    echo "File already Exits";
    $new_name= $fname.'_'.date('dmY').'.'.$ext;

    ssh2_sftp_rename($sftp, '/var/www/html/Dev/File_upload/doc/byroll/'.$batch.'/'.$pid.'/'.$pname.'', '/var/www/html/Dev/File_upload/doc/byroll/'.$batch.'/'.$pid.'/'.$new_name.'');
}

$result = ssh2_scp_send($connection, $local_file, $remote_file, 0644);

if(!$result) {
    echo 'Error while uploading';
    
}
else{

echo 'Uploaded successfully!'."\n";

}
}

我的输出是下面

and after index 9 it not allowing any double digit number to it

【问题讨论】：

您可能遇到了限制，因为某些东西没有正确关闭连接。在花了很多很多小时修复奇怪的边缘情况错误并处理“它在我的机器上工作”之后，每当我需要 SSH、SCP 或 SFTP 时，我总是去phpseclib，我会鼓励你也这样做。它有SCP support 和通常更好的错误消息。我并不是说你的方法是错误的，只是说这是我的首选工具，到目前为止，我每次使用它时“都能正常工作”。
似乎问题不在于数组变量，它似乎与限制或缓冲时间有关.....

【解决方案1】：

您启动 SFTP 会话 (ssh2_sftp)，而稍后您使用 SCP 进行实际传输 (ssh2_scp_send)。您绝对不需要 ssh2_sftp 行；它实际上可能是您的问题的原因。虽然从技术上讲，可以通过一个 SSH 连接同时进行 SFTP 和 SCP 会话，但我不希望 PHP 支持这一点。虽然我不确定。

我在我的代码中注释了 SFTP 部分并通过 ssh2 上传了 50 多个文件

所有 57 个文件都已从本地服务器移动到远程服务器，并且运行良好
