ssh2_scp_send — Send a file via SCP
$session
, string $local_file
, string $remote_file
[, int $create_mode = 0644
] )Copy a file from the local filesystem to the remote server using the SCP protocol.
sessionAn SSH connection link identifier, obtained from a call to ssh2_connect().
local_filePath to the local file.
remote_filePath to the remote file.
create_mode
The file will be created with the mode specified by
create_mode.
成功时返回 TRUE， 或者在失败时返回 FALSE。
Example #1 Uploading a file via SCP
<?php
$connection = ssh2_connect('shell.example.com', 22);
ssh2_auth_password($connection, 'username', 'password');
ssh2_scp_send($connection, '/local/filename', '/remote/filename', 0644);
?>
In case the command:
$sftpStream = @fopen('ssh2.sftp://'.$sftp.$dstFile, 'w');
causes you a segmentation fault, try using:
$sftpStream = @fopen('ssh2.sftp://'.intval($sftp).$dstFile, 'w');

solution of uploading dir with space (don't forget " symbols)
<?php
ssh2_scp_send($connection, '/local/file with space.txt', '"/remote/file with space.txt"', 0777);
?>
If the server you are sending to is ubuntu 8 or 9 and you can't send files then check that your user has write permissions for /dev/null. Gets me every time. Add the line:
chmod 666 /dev/null
to /etc/rc.local before the exit 0 line.
On Windows, I had trouble using ssh2_scp_send: files copied to a remote server where incomplete (truncated) and/or locked (error message : "access denied"). The back-end is also on Windows, using CopSSH (cygwin-based SSH server).
The SSH session was kept open - and the file were never flushed to disk.
There's a workaround though - make an explicit call to "exit" to close the session (flushing file content to disk):
<?php
$objConnection = ssh2_connect($strHost, $strPort, $methods, $callbacks);
ssh2_auth_password($objConnection, $strUser, $strPassword);
ssh2_scp_send($objConnection , $strSource, $strDest);
// Add this to flush buffers/close session
ssh2_exec($objConnection, 'exit');
?>
In addition to my previous post, I figured out that sftp->fopen->file_get_contents->fwrite has much better performance than ssh2_scp_send.
I've used the following code to test:
<?php
$srcFile = '/var/tmp/dir1/file_to_send.txt';
$dstFile = '/var/tmp/dir2/file_received.txt';
// Create connection the the remote host
$conn = ssh2_connect('my.server.com', 22);
// 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);
}
?>
For the test I've sent three files with total size of 6kB, and the times to send including connect to the server were:
SFTP -> 15 sec.
ssh2_scp_send -> 22 sec.

After some testing I figured out that ssh2_scp_send does not work exactly as the standard scp command:
- Works: ssh2_scp_send($conn, '/var/tmp/file_01.txt', /var/tmp/file_02.txt');
- Wrong: ssh2_scp_send($conn, '/var/tmp/file_01.txt', /var/tmp'); (Creates file with name 'tmp')
- Fails: ssh2_scp_send($conn, '/var/tmp/file_01.txt', /var/tmp/');
- Fails: ssh2_scp_send($conn, '/dirname', /var/tmp/'); (No recursion)
- Fails: ssh2_scp_send($conn, '/dirname/*', /var/tmp/'); (Cannot copy more than one file.)
Cheers,
