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 assumes 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.SFtp')
$sftp = new COM("Chilkat.SFtp");

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

// Authenticate with the SSH server.  Chilkat SFTP supports
// both password-based authenication as well as public-key
// authentication.  This example uses password authenication.
$success = $sftp->AuthenticatePw('myLogin','myPassword');
if ($success != 1) {
    print $sftp->LastErrorText . "\n";
    exit;
}

// After authenticating, the SFTP subsystem must be initialized:
$success = $sftp->InitializeSftp();
if ($success != 1) {
    print $sftp->LastErrorText . "\n";
    exit;
}

// Check to see if a file exists

// The return value is one of the following values:
// -1: Unable to check. Examine the LastErrorText to determine the reason for failure.
// 0: File does not exist.
// 1: The regular file exists.
// 2: It exists, but it is a directory.
// 3: It exists, but it is a symlink (only possible if followLinks is false)
// 4: It exists, but it is a special filesystem entry type.
// 5: It exists, but it is an unkown filesystem entry type.
// 6: It exists, but it is an socket filesystem entry type.
// 7: It exists, but it is an char device entry type.
// 8: It exists, but it is an block device entry type.
// 9: It exists, but it is an FIFO entry type.

$followLinks = 1;
$status = $sftp->FileExists('someDir/someFile.txt',$followLinks);
if ($status < 0) {
    print $sftp->LastErrorText . "\n";
    exit;
}

print 'status = ' . $status . "\n";

print 'Success' . "\n";
