PHP ソケットがサーバーテンプレートに接続する、ソケットサーバー

PHPのソケットはサーバーテンプレートに接続されており、ソケットサーバー

新しいフレームワークを整理していると、キャッシュされたデータの一部には外部インターフェースアクセスが必要で、より便利なのはphpインターフェースであることが判明したので、一時的に勉強しましたPHPをJavaサーバーに接続する方法。

最初にコードを貼り付けます。

<?php
require_once 'CRC16.php';
/*-----------------------------
 | 向服务器发送数据包
 ------------------------------*/
classServer{
//发送数据包
publicstaticfunction sendPacket($packet, $host, $port){
 $protocol ='tcp';
 $get_prot = getprotobyname ( $protocol );
//创建socket
 $socket = socket_create ( AF_INET, SOCK_STREAM, $get_prot );
//建立连接
 $conn = socket_connect ( $socket, $host, $port );
if(!$conn){
 socket_close($socket);
exit("socket connect failed!");
}
 $buffer =@socket_read($socket,9, PHP_NORMAL_READ); $buffer
= $crcCode =(ord($buffer[7])<<8)+ord($buffer[8]);@socket_read
( $len = strlen($packet);$socket
, $newpacket = CRC16::encode($packet, $crcCode,4);9
, socket_send ( $socket, $newpacket, $len,0); PHP_NORMAL_READ
);//等待接受
 $head =@socket_read($socket,4,PHP_NORMAL_READ);

個人サーバーに接続した後、crcCode 検証コードが割り当てられ、送信されるメッセージは crc16 で暗号化される必要があるため (実際には非常に単純ですが、謎めいたままにしておきます)、最初に crcCode を取得するために固定長が受け入れられるのを待ちます。、リクエストを送信し、パケットが受け入れられて返されるのを待ちます。

PHP の Socket はサーバーとクライアントの間でどのように通信しますか?

サーバーはデータバッファを提供し、ユーザー識別メカニズムを提供します。これは、両方のチャットユーザーに対応する情報を送信するために使用されます。
ユーザー間の通信は、実際にはユーザーがサーバーと通信しているようです。
私の少しの理解

phpソケットに接続できません

ポートを確認してください
