Receive a Bounded String from a Socket

See more Socket/SSL/TLS Examples

Demonstrates Socket.ReceiveStringMaxN, which receives and decodes text like ReceiveString but reads at most a given number of input bytes.

<?php

use Chilkat2\Socket;

$socket = new Socket();

// Connect to the server using TLS.  The 3rd argument enables the TLS handshake after the TCP
// connection succeeds; the 4th is the maximum time to wait, in milliseconds.
$bTls = true;
$maxWaitMs = 5000;
try {
    $socket->Connect('example.com', 5000, $bTls, $maxWaitMs);

    // StringCharset controls the character encoding used when sending and receiving text.
    $socket->StringCharset = 'utf-8';
    // Send a request using a simple application-defined text protocol in which each message ends with a
    // CRLF.
    $command = "STATUS\r\n";
    $socket->SendString($command);

    // Receive and decode text like ReceiveString, but read at most the given number of input bytes.
    // The limit is measured in bytes, not Unicode characters.
    $firstChunk = $socket->ReceiveStringMaxN(64);
} catch (\Chilkat2\Exception $e) {
    echo $e->getMessage(), "\n";
    exit;
}

echo $firstChunk, "\n";
