php使用socket编程示例

2个php测试文件
server.php

复制代码 代码如下:
//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;

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);

       
        $talkback = "收到的信息:$bufn";
        echo $talkback;

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

   
    }
    //echo $buf;
    socket_close($msgsock);

} while (true);

socket_close($sock);
?>

client.php
复制代码 代码如下:
error_reporting(E_ALL);
set_time_limit(0);
echo "TCP/IP Connectionn";

$port = 1935;
$ip = "127.0.0.1";

$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
if ($socket < 0) {
    echo "socket_create() failed: reason: " . socket_strerror($socket) . "n";
}else {
    echo "OK.n";
}

echo "试图连接 '$ip' 端口 '$port'...n";
$result = socket_connect($socket, $ip, $port);
if ($result < 0) {
    echo "socket_connect() failed.nReason: ($result) " . socket_strerror($result) . "n";
}else {
    echo "连接OKn";
}

$in = "Horn";
$in .= "first bloodrn";
$out = '';

if(!socket_write($socket, $in, strlen($in))) {
    echo "socket_write() failed: reason: " . socket_strerror($socket) . "n";
}else {
    echo "发送到服务器信息成功！n";
    echo "发送的内容为:$in
";
}

while($out = socket_read($socket, 8192)) {
    echo "接收服务器回传信息成功！n";
    echo "接受的内容为:",$out;
}

echo "关闭SOCKET...n";
socket_close($socket);
echo "关闭OKn";
?>

侦听
复制代码 代码如下:
# /usr/local/php/bin/php  /usr/local/apache2/htdocs/server.php

请求复制代码 代码如下:
# /usr/local/php/bin/php  /usr/local/apache2/htdocs/client.php

默认PHP是没有开启Socket的
 复制代码 代码如下:
#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
复制代码 代码如下:
extension=sockets.so


重启apache
复制代码 代码如下:
# /usr/local/apache2/bin/apachectl restart


Windows下的配置
修改php.ini
复制代码 代码如下:
extension=php_sockets.dll

重启apache
cmd下起2个
php的安装目录

 复制代码 代码如下:
C:/php/php.exe   F:web/server.php
C:/php/php.exe   F:web/client.php
