Receive Text up to a Matching Sequence

See more Socket/SSL/TLS Examples

Demonstrates Socket.ReceiveUntilMatch, which receives bytes until an exact byte sequence is found. The match string is encoded using StringCharset and compared byte-for-byte.

<?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 bytes until an exact byte sequence is found.  The match string is encoded using
//  StringCharset and compared byte-for-byte.  Here the server marks the end of its response with an
//  application-defined marker.
$response = $socket->receiveUntilMatch('<EOM>');
if ($socket->LastMethodSuccess == 0) {
    print $socket->LastErrorText . "\n";
    exit;
}

print $response . "\n";
