This line...
while(($buf = socket_read($socket,128,PHP_BINARY_READ)) !==
false) {...is what returns the error. The whole loop (which needs to keep running).
$msg_recv = 3;
do {
$data = "";
socket_set_block($socket);
socket_set_option($socket,SOL_SOCKET,SO_RCVTIMEO,$timeout);
while(($buf = socket_read($socket,128,PHP_BINARY_READ)) !== false) { // THIS IS WHERE IT CHOKES
$data .= $buf;
if(preg_match("/ENX/",$data)) {
$msg_recv = 1;
break;
} elseif ($error = socket_last_error($socket)) {
$msg_recv = 0;
echo "\nTIMEOUT: SOCKET ERROR [$error]:" . socket_strerror($error);
break;
}
}
if ($msg_recv == 1) {
echo "\nMESSAGE RECEIVED\n";
$msg_recv = 3;
} elseif ($msg_recv == 0) {
echo "\nTIMEOUT: MESSAGE NOT RECEIVED\n";
$msg_recv = 3;
}} while ($connection == true);
And the output:
MESSAGE RECEIVED

you need to use break 2; to exit the while and the do - while or set $connection = false;
