一、开启socket
phpinfo();查看是否开启了socket扩展,否则在php.ini中开启。
二、服务器端代码的写法
- <?php
- error_reporting(E_ALL);
- set_time_limit(0);
- //ob_implicit_flush();
- $address = "127.0.0.1";
- $port = 10005;
- //创建端口
- if( ($sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)) === false) {
- echo "socket_create() failed :reason:" . socket_strerror(socket_last_error()) . "\n";
- }
- //绑定
- if (socket_bind($sock, $address, $port) === false) {
- echo "socket_bind() failed :reason:" . socket_strerror(socket_last_error($sock)) . "\n";
- }
- //监听
- if (socket_listen($sock, 5) === false) {
- echo "socket_bind() failed :reason:" . socket_strerror(socket_last_error($sock)) . "\n";
- }
- do {
- //得到一个链接
- if (($msgsock = socket_accept($sock)) === false) {
- echo "socket_accepty() failed :reason:".socket_strerror(socket_last_error($sock)) . "\n";
- break;
- }
- //welcome 发送到客户端
- $msg = "<font color="red">server send:welcome</font><br/>";
- socket_write($msgsock, $msg, strlen($msg));
- echo "read client message\n";
- $buf = socket_read($msgsock, 8192);
- $talkback = "received message:$buf\n";
- echo $talkback;
- if (false === socket_write($msgsock, $talkback, strlen($talkback))) {
- echo "socket_write() failed reason:" . socket_strerror(socket_last_error($sock)) ."\n";
- } else {
- echo "send success";
- }
- socket_close($msgsock);
- } while(true);
- //关闭socket
- socket_close($sock);
- ?>

服务器端需要在cli模式是执行,有可能cli模式下php.ini文件载入的不一样
可以像如下输出
这时候在zhoxh目录下就有个tem.text文件。查看 Configuration File (php.ini) Path => C:\WINDOWS 。不是我的php.ini 文件,这说明调用的php.ini文件时错误的。这时候我们要指定php.ini文件命令如下
注意的是我的php可以直接执行时配置了环境变量。
三、客户端
- <?php
- //error_reporting(E_ALL);
- [url=http://www.php.net/echo]echo[/url] "<h2>tcp/ip connection </h2>\n";
- $service_port = 10005;
- $address = "127.0.0.1";
- $[url=http://www.php.net/socket]socket[/url] = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
- [url=http://www.php.net/if]if[/url] ($[url=http://www.php.net/socket]socket[/url] === [url=http://www.php.net/false]false[/url]) {
- [url=http://www.php.net/echo]echo[/url] "socket_create() failed: reason: " . socket_strerror(socket_last_error()) . "\n";
- } [url=http://www.php.net/else]else[/url] {
- [url=http://www.php.net/echo]echo[/url] "OK. \n";
- }
- [url=http://www.php.net/echo]echo[/url] "Attempting to connect to "$address" on port "$service_port"...";
- $result = socket_connect($[url=http://www.php.net/socket]socket[/url], $address, $service_port);
- [url=http://www.php.net/if]if[/url]($result === [url=http://www.php.net/false]false[/url]) {
- [url=http://www.php.net/echo]echo[/url] "socket_connect() failed.\nReason: ($result) " . socket_strerror(socket_last_error($[url=http://www.php.net/socket]socket[/url])) . "\n";
- } [url=http://www.php.net/else]else[/url] {
- [url=http://www.php.net/echo]echo[/url] "OK \n";
- }
- $in = "HEAD / http/1.1\r\n";
- $in .= "HOST: localhost \r\n";
- $in .= "Connection: close\r\n\r\n";
- $out = "";
- [url=http://www.php.net/echo]echo[/url] "sending http head request ...";
- socket_write($[url=http://www.php.net/socket]socket[/url], $in, [url=http://www.php.net/strlen]strlen[/url]($in));
- [url=http://www.php.net/echo]echo[/url] "OK\n";
- [url=http://www.php.net/echo]echo[/url] "Reading response:\n\n";
- [url=http://www.php.net/while]while[/url] ($out = socket_read($[url=http://www.php.net/socket]socket[/url], 8192)) {
- [url=http://www.php.net/echo]echo[/url] $out;
- }
- [url=http://www.php.net/echo]echo[/url] "closeing socket..";
- socket_close($[url=http://www.php.net/socket]socket[/url]);
- [url=http://www.php.net/echo]echo[/url] "ok .\n\n";
