Demonstrates how to open a text file on the SSH server and read text.

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.

// 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");

// Set some timeouts, in milliseconds:
$sftp->ConnectTimeoutMs = 5000;
$sftp->IdleTimeoutMs = 15000;

// Connect to the SSH server.  
// The standard SSH port = 22
// The hostname may be a hostname or IP address.
$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;
}

// Open a file for reading.

$handle = $sftp->openFile('myTest.txt','readOnly','openExisting');
if ($sftp->LastMethodSuccess != 1) {
    print $sftp->LastErrorText . "\n";
    exit;
}

// Assume the file we are reading contains the following text:
// abcdefghijklmnopqrstuvwxyz1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ
// (in ANSI format -- i.e. one byte per char).

// Read 26 bytes:

$sText = $sftp->readFileText($handle,26,'ansi');
if ($sftp->LastMethodSuccess != 1) {
    print $sftp->LastErrorText . "\n";
    exit;
}

// Should print "abcdefghijklmnopqrstuvwxyz"
print $sText . "\n";

// Read the next 10 bytes.
$sText = $sftp->readFileText($handle,10,'ansi');
if ($sftp->LastMethodSuccess != 1) {
    print $sftp->LastErrorText . "\n";
    exit;
}

// Should print "1234567890"
print $sText . "\n";

// Read the next 26 bytes.

if ($sftp->LastMethodSuccess != 1) {
    print $sftp->LastErrorText . "\n";
    exit;

// Should print "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
print $sText . "\n";

// Close the file.
$success = $sftp->CloseHandle($handle);
