Receive a 16-bit Integer from a Socket

See more Socket/SSL/TLS Examples

Demonstrates Socket.ReceiveInt16, which reads exactly two bytes as a 16-bit integer and stores the result in the ReceivedInt property. Byte order and signedness are selectable.

<?php

$success = 0;

$socket = new COM("Chilkat.Socket");

//  Connect to the server using TLS.
$bTls = 1;
$maxWaitMs = 5000;
$success = $socket->Connect('example.com',5000,$bTls,$maxWaitMs);
if ($success == 0) {
    print $socket->LastErrorText . "\n";
    exit;
}

//  Read exactly two bytes as a 16-bit integer and store the result in the ReceivedInt property.
//  The 1st argument selects byte order (1 = big-endian); the 2nd selects unsigned interpretation.
$bBigEndian = 1;
$bUnsigned = 0;
$success = $socket->ReceiveInt16($bBigEndian,$bUnsigned);
if ($success == 0) {
    print $socket->LastErrorText . "\n";
    exit;
}

print 'Received 16-bit integer: ' . $socket->ReceivedInt . "\n";
