Recently I had to use ssh2 through php in order to send files from one server to another. I don’t know why, I was getting a error that was not actually very common on the Internet. My code was:
$connection = ssh2_connect($host, $port); ssh2_scp_send($connection, $path_origin, $path_target, 0644);
The connection was correctly placed, but when trying to copy the file, I got:
Warning: ssh2_scp_send(): Failure creating remote file: Invalid ACK response from remote
After looking for the solution, I finally found something [not really related to this issue]. There are other ways of copying files through ssh using php, and that’s what I did. Here is the workaround I found:
<?php
$srcFile = '/path_to_origin_file';
$dstFile = '/path_to_server_file';
$host = 'ssh_host';
$port = '22';
$username = 'ssh_user';
$password = 'ssh_password';
// Create connection the the remote host
$conn = ssh2_connect($host, $port);
ssh2_auth_password($conn, $username, $password);
// Create SFTP session
$sftp = ssh2_sftp($conn);
$sftpStream = fopen('ssh2.sftp://'.$sftp.$dstFile, 'w');
try {
if (!$sftpStream) {
throw new Exception("Could not open remote file: $dstFile");
}
$data_to_send = file_get_contents($srcFile);
if ($data_to_send === false) {
throw new Exception("Could not open local file: $srcFile.");
}
if (fwrite($sftpStream, $data_to_send) === false) {
throw new Exception("Could not send data from file: $srcFile.");
}
fclose($sftpStream);
} catch (Exception $e) {
error_log('Exception: ' . $e->getMessage());
fclose($sftpStream);
}
?>

After messing with ssh2_scp_send() for two days, I determined that the filename must be quoted and permissions string unquoted. In your case, I would try the following:
ssh2_scp_send($connection, “$path_origin”, “$path_target”, 0644);
