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.

use chilkat();

$success = 0;

$socket = chilkat::CkSocket->new();

#  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() . "\r\n";
    exit;
}

#  StringCharset controls the character encoding used when sending and receiving text.
$socket->put_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() . "\r\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->get_LastMethodSuccess() == 0) {
    print $socket->lastErrorText() . "\r\n";
