php socket通信(tcp/udp)实例分析

本文实例讲述了php socket通信(tcp/udp)方法。分享给大家供大家参考，具体如下：

注意

1.在socket_bind的时候ip地址不能真回环地址如127.0.0.1
2.server.php后台跑起来的时候nohup php server.php > /var/tmp/a.log 2>&1 &

一： udp 方式

1. server.php

    <?php
    //error_reporting( E_ALL );
    set_time_limit( 0 );
    ob_implicit_flush();
    $socket = socket_create( AF_INET, SOCK_DGRAM, SOL_UDP );
    if ( $socket === false ) {
      echo "socket_create() failed:reason:" . socket_strerror( socket_last_error() ) . "\n";
    }
    $ok = socket_bind( $socket, '202.85.218.133', 11109 );
    if ( $ok === false ) {
      echo "socket_bind() failed:reason:" . socket_strerror( socket_last_error( $socket ) );
    }
    while ( true ) {
      $from = "";
      $port = 0;
      socket_recvfrom( $socket, $buf,1024, 0, $from, $port );
      echo $buf;
      usleep( 1000 );
    }
    ?>

2. client.php

    <?php
    $sock = socket_create(AF_INET, SOCK_DGRAM, SOL_UDP);
    $msg = 'hello';
    $len = strlen($msg);
    socket_sendto($sock, $msg, $len, 0, '202.85.218.133', 11109);
    socket_close($sock);
    ?>

二： TCP 方式

1)server.php

    <?php
    //error_reporting( E_ALL );
    set_time_limit( 0 );
    ob_implicit_flush();
    $socket = socket_create( AF_INET, SOCK_STREAM, SOL_TCP );
    socket_bind( $socket, '192.168.2.143', 11109 );
    socket_listen($socket);
    $acpt=socket_accept($socket);
    echo "Acpt!\n";
    while ( $acpt ) {
      $words=fgets(STDIN);
      socket_write($acpt,$words);
      $hear=socket_read($acpt,1024);
      echo $hear;
      if("bye\r\n"==$hear){
        socket_shutdown($acpt);
        break;
      }
      usleep( 1000 );
    }
    socket_close($socket)
    ?>

2. client.php

    <?php
    $socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
    $con=socket_connect($socket,'192.168.2.143',11109);
    if(!$con){socket_close($socket);exit;}
    echo "Link\n";
    while($con){
        $hear=socket_read($socket,1024);
        echo $hear;
        $words=fgets(STDIN);
        socket_write($socket,$words);
        if($words=="bye\r\n"){break;}
    }
    socket_shutdown($socket);
    socket_close($sock);
    ?>
