ssh2_scp_recv
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,
