PHP for TCP connection

This article to everyone to share the content is PHP TCP connection, has a certain reference value, the need for friends can refer to

The native PHP notation.

$host = ' server IP ';    $port = port number;    $timeout = 5;    $socket = Socket_create (Af_inet, Sock_stream, sol_tcp);    if (Socket_connect ($socket, $host, $port) = = = False) {//Create connection        socket_close ($socket);        $message = ' Create socket error ';        throw new Exception ($message, Socket_last_error ());    }       if (Socket_write ($socket, $buffer) = = = False) {//bundle        Socket_close ($socket);        $message = sprintf ("Write Socket error:%s", Socket_strerror (Socket_last_error ()));        throw new Exception ($message, Socket_last_error ());    }       Socket_set_option ($socket, Sol_socket, So_rcvtimeo, $timeout);    $rspBuffer = Socket_read ($socket, 65536); Pick-up Package    socket_close ($socket);

Use the swoole notation.

$client = new Swoole_client (swoole_sock_tcp, swoole_sock_sync); $ret = $client->connect (' Server IP ', port number, 0.5, 0);  Create a connection if (! $ret) {    throw new Exception (' Connect error ', $client->errcode);}   $client->send ($buffer); Contract $rspbuffer = $client->recv (); Pick up the package
