php socket 修正 Server 與 Client 實作 (一)

目的：
1.Server端：能接收client傳來的訊息並寫入檔案且不傳訊息給client
2.Client端：不接收server傳來的訊息

Server端IP:192.168.32.102 Port:25001
檔名：ServerSocket.php ，檔案所在位置為 /home/webadmin/ServerSocket.php

<?php
$server_ip = '192.168.32.102';
$port = 25001;
$socket = socket_create(AF_INET,SOCK_STREAM,SOL_TCP);
socket_bind($socket,$server_ip,$port);
socket_listen($socket,SOMAXCONN);
$count = 0;
do {
    $msgsocket = socket_accept($socket);
    if ($msgsocket < 0) {
        echo "socket_accept() fail : ".socket_strerror(socket_last_error())."\n";
        break;
    } else {
        $datetime = date('Y-m-d H:i:s',time());
        $str = "Server datetime:{$datetime}\n";
        $buff = socket_read($msgsocket,2048);
        $str .= "Receive client message: {$buff}"." count: ".$count."\n\n";
        echo $str;
        $str01 = $buff." ".$datetime."\n";
        if ($str01!="") {
            $file = fopen("/home/webadmin/html/ServerSocket", "a+");
            fwrite($file, $str01);
            fclose($file);
        }
    }
    $count++;
    socket_close($msgsocket);
} while ($count <= 5);
socket_close($socket);
?>

執行 ServerSocket.php 的指令
$php ServerSocket.php

Client端：IP:192.168.32.182

檔名：client.php

傳送$in 的內容給 Server 端

<?php

$server_ip = '192.168.32.102';

$port = 25001;

$socket = socket_create(AF_INET,SOCK_STREAM,SOL_TCP);

socket_connect($socket,$server_ip,$port);

$in = "\$\$H167,864292040653451,AAA,35\n";

socket_write($socket,$in,strlen($in));

socket_close($socket);

?>
執行client.php的指令
$php client.php

另外，在Server端的/home/webadmin/html/ 會出現一個檔案為ServerSocket
其內容為
