php 如何监听服务器端口

Answer 1

<?php
//设置运行时间:永不超时
set_time_limit (0);

//开启缓冲
ob_implicit_flush ();

//IP地址
$ip = "127.0.0.1";

//监听端口
$port = 80;

//创建socket
$socket = socket_create (AF_INET, SOCK_STREAM, 0);
if (!$socket){
die("创建socket失败！").socket_strerror(socket_last_error());
}

//绑定socket
$bind = socket_bind ($socket, $ip, $port);
if (!$bind){
die("绑定.socket失败！").socket_strerror ($bind);
}

//监听socket
$listen = socket_listen ($socket);
if (!$listen){

die("监听失败！").socket_strerror ($listen);
}
echo "{$port}端口监听成功!";
?>
