Receive an Exact Number of Bytes into a BinData

See more Socket/SSL/TLS Examples

Demonstrates Socket.ReceiveBdN, which receives exactly the requested number of bytes and appends them to a BinData, continuing until the full count is satisfied.

<?php

include("chilkat.php");

$success = false;

$socket = new CkSocket();

//  Connect to the server using TLS.
$bTls = true;
$maxWaitMs = 5000;
$success = $socket->Connect('example.com',5000,$bTls,$maxWaitMs);
if ($success == false) {
    print $socket->lastErrorText() . "\n";
    exit;
}

//  MaxReadIdleMs controls the inactivity limit for receiving.  The ReceiveBdN call will fail if
//  incoming bytes halt for longer than this many milliseconds before the full amount is received.
$socket->put_MaxReadIdleMs(15000);

//  Receive exactly the requested number of bytes, appending them to a BinData.  The method continues
//  receiving until the full count is satisfied or a failure occurs.
$bd = new CkBinData();
$success = $socket->ReceiveBdN(256,$bd);
if ($success == false) {
    print $socket->lastErrorText() . "\n";
    exit;
}

print 'Received ' . $bd->get_NumBytes() . ' bytes.' . "\n";
