基于PHP Socket配置以及实例的详细介绍

2017-4-8 admin CentOS

本文文章是对PHP中Socket的配置以及实例进行了详细的分析介绍，需要的朋友参考下

2个php测试文件
server.php

<?php
     //phpinfo();
//确保在连接客户端时不会超时
set_time_limit(0);
$ip = '127.0.0.1';
$port = 1935;
/*
 +-------------------------------
 *    @socket通信整个过程
 +-------------------------------
 *    @socket_create
 *    @socket_bind
 *    @socket_listen
 *    @socket_accept
 *    @socket_read
 *    @socket_write
 *    @socket_close
 +--------------------------------
 */
/*----------------    以下操作都是手册上的    -------------------*/
if(($sock = socket_create(AF_INET,SOCK_STREAM,SOL_TCP)) < 0) {
    echo "socket_create() 失败的原因是:".socket_strerror($sock)."\n";
}
if(($ret = socket_bind($sock,$ip,$port)) < 0) {
    echo "socket_bind() 失败的原因是:".socket_strerror($ret)."\n";
}
if(($ret = socket_listen($sock,4)) < 0) {
    echo "socket_listen() 失败的原因是:".socket_strerror($ret)."\n";
}
$count = 0;
do {
    if (($msgsock = socket_accept($sock)) < 0) {
        echo "socket_accept() failed: reason: " . socket_strerror($msgsock) . "\n";
        break;
    } else {

        //发到客户端
        $msg ="测试成功！\n";
        socket_write($msgsock, $msg, strlen($msg));

        echo "测试成功了啊\n";
        $buf = socket_read($msgsock,8192);

        
        $talkback = "收到的信息:$buf\n";
        echo $talkback;

        if(++$count >= 5){
            break;
        };

    
    }
    //echo $buf;
    socket_close($msgsock);
} while (true);
socket_close($sock);
?>

client.php

<?php
     //phpinfo();
//确保在连接客户端时不会超时
set_time_limit(0);
$ip = '127.0.0.1';
$port = 1935;

侦听
＃/ usr / local / php / bin / php /usr/local/apache2/htdocs/server.php

请求
＃/ usr / local / php / bin / php /usr/local/apache2/htdocs/client.php

默认PHP是没有开启Socket的
 

#cd ./ext/sockets/

＃/ usr / local / php / bin / phpize

＃./configure --enable-sockets --with-php-config = / usr / local / php / bin / php-config

＃make

＃make install

php.ini修改配置

增加

extension = sockets.so
 

重启apache
＃/ usr / local / apache2 / bin / apachectl restart

===================

Windows下的配置
修改php.ini

extension = php_sockets.dll

重启apache

cmd下起2个

php的安装目录

C：/php/php.exe F：web / server.php

C：/php/php.exe F：web / client.php
