See more SSH Examples

Demonstrates the simplified way to run multiple commands in a shell session on an SSH server.

Chilkat ActiveX Downloads

ActiveX for 32-bit and 64-bit Windows

Note: The php_com_dotnet.dll may need to be enabled inside of php.ini.

<?php

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Ssh')
$ssh = new COM("Chilkat.Ssh");

$port = 22;
$success = $ssh->Connect('the-ssh-server.com',$port);
if ($success != 1) {
    print $ssh->LastErrorText . "\n";
    exit;
}

// Authenticate using login/password:
$success = $ssh->AuthenticatePw('theSshLogin','theSshPassword');
if ($success != 1) {
    print $ssh->LastErrorText . "\n";
    exit;
}

// Start a shell session.
// (The QuickShell method was added in Chilkat v9.5.0.65)
$channelNum = $ssh->QuickShell();
if ($channelNum < 0) {
    print $ssh->LastErrorText . "\n";
    exit;
}

// Construct a StringBuilder with multiple commands, one per line.
// Note: The line-endings are potentially important.  Some SSH servers may
// require either LF or CRLF line endings.  (Unix/Linux/OSX servers typically
// use bare-LF line endings.  Windows servers likely use CRLF line endings.)
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.StringBuilder')
$sbCommands = new COM("Chilkat.StringBuilder");
$sbCommands->Append('echo hello world\n');
$sbCommands->Append('date\n');
$sbCommands->Append('df\n');

// For our last command, we're going to echo a marker string that
// we'll use in ChannelReceiveUntilMatch below.
// The use of single quotes around 'IS' is a trick so that the output
// of the command is "THIS IS THE END OF THE SCRIPT", but the terminal echo
// includes the single quotes.  This allows us to read until we see the actual
// output of the last command.
$sbCommands->Append('echo THIS 'IS' THE END OF THE SCRIPT\n');

// Send the commands..
$success = $ssh->ChannelSendString($channelNum,$sbCommands->getAsString(),'ansi');
if ($success != 1) {
    print $ssh->LastErrorText . "\n";
    exit;
}

// Send an EOF to indicate no more commands will be sent.
// For brevity, we're not checking the return values of each method call.
// Your code should check the success/failure of each call.
$success = $ssh->ChannelSendEof($channelNum);

// Receive output up to our marker.
$success = $ssh->ChannelReceiveUntilMatch($channelNum,'THIS IS THE END OF THE SCRIPT','ansi',1);

// Close the channel.
// It is important to close the channel only after receiving the desired output.
$success = $ssh->ChannelSendClose($channelNum);

// Get any remaining output..
$success = $ssh->ChannelReceiveToClose($channelNum);

// Get the complete output for all the commands in the session.
print '--- output ----' . "\n";
print $ssh->getReceivedText($channelNum,'ansi') . "\n";

// Here's our actual sample output:

// 	Last login: Thu Dec 22 20:19:09 2016 from chilkat13
// 
// 	echo hello world
// 	date
// 	df
// 	echo THIS 'IS' THE END OF THE SCRIPT
