~ Socket Server and Client side in php ~

首先要setup 好server side , 變更host and port

完成後要係putty 開啟server

php -q socket_server.php

<?php
//php -q socket_server.php
// 设置一些基本的变量
global $lat,$lnt;
$host = "192.168.0.1";
$port = 8888;
// 设置超时时间
set_time_limit(0);
// 创建一个Socket
$commonProtocol = getprotobyname("tcp");
$socket = socket_create(AF_INET, SOCK_STREAM, $commonProtocol);
 
//绑定Socket到端口
$result = socket_bind($socket, $host, $port) or die("Could not bind to socket\n");
$ret = socket_listen($socket, 5);
if($ret){
    while (true){
        $spawn = socket_accept($socket) or die("Could not accept incoming connection\n");;
        echo("socket connected\n");
        if(!$spawn) break;
        $output = "Welcome to the PHP Test Server.....nice\n";
        socket_write($spawn, $output, strlen ($output)) or die("error\n");
        while($input = socket_read($spawn, 64)){
            echo($input);
        }
        echo("\n");
        socket_close($spawn);
    }
}
?>

Client Side

<?php
// 设置一些基本的变量
$host = "192.168.0.1";
$port = 8888;
// 设置超时时间
set_time_limit(0);
// 创建一个Socket
$commonProtocol = getprotobyname("tcp");
$socket = socket_create(AF_INET, SOCK_STREAM, $commonProtocol);
if(!$socket) echo "can't create socket";
//绑定Socket到端口
$result = socket_connect($socket, $host, $port) or die(socket_strerror());
if($result){
    $output="hello server!,connie";//lat:30.582029016593196;lnt:103.98662567138672
    socket_write($socket, $output, strlen ($output));
    $input = socket_read($socket, 1024);
    echo($input);
}
?>

之後係web browser 開client url , 便可以
