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

$success = 0;

$socket = new COM("Chilkat.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 = 1;
$maxWaitMs = 5000;
$success = $socket->Connect('example.com',5000,$bTls,$maxWaitMs);
if ($success == 0) {
    print $socket->LastErrorText . "\n";
    exit;
}

//  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';
$success = $socket->SendString($command);
if ($success == 0) {
    print $socket->LastErrorText . "\n";
    exit;
}

//  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 = $socket->receiveStringMaxN(64);
if ($socket->LastMethodSuccess == 0) {
    print $socket->LastErrorText . "\n";
    exit;
}

print $firstChunk . "\n";
