详解php中socket的用法（附服务器端和客户端的示例代码）

php中socket的具体用法如下：
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
代码如下:
02 | error_reporting(E_ALL); |
05 | $address = '127.0.0.1'; |
08 | if( ($sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)) === false) { |
09 | echo "socket_create() failed :reason:" . socket_strerror(socket_last_error()) . "\n"; |
12 | if (socket_bind($sock, $address, $port) === false) { |
13 | echo "socket_bind() failed :reason:" . socket_strerror(socket_last_error($sock)) . "\n"; |
16 | if (socket_listen($sock, 5) === false) { |
17 | echo "socket_bind() failed :reason:" . socket_strerror(socket_last_error($sock)) . "\n"; |
21 | if (($msgsock = socket_accept($sock)) === false) { |
22 | echo "socket_accepty() failed :reason:".socket_strerror(socket_last_error($sock)) . "\n"; |
26 | $msg = "<font color='red'>server send:welcome</font> |
28 | socket_write($msgsock, $msg, strlen($msg)); |
29 | echo 'read client message\n'; |
30 | $buf = socket_read($msgsock, 8192); |
31 | $talkback = "received message:$buf\n"; |
33 | if (false === socket_write($msgsock, $talkback, strlen($talkback))) { |
34 | echo "socket_write() failed reason:" . socket_strerror(socket_last_error($sock)) ."\n"; |
38 | socket_close($msgsock); |
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
代码如下:
03 | echo "<h2>tcp/ip connection </h2>\n"; |
04 | $service_port = 10005; |
05 | $address = '127.0.0.1'; |
06 | $socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP); |
07 | if ($socket === false) { |
08 | echo "socket_create() failed: reason: " . socket_strerror(socket_last_error()) . "\n"; |
12 | echo "Attempting to connect to '$address' on port '$service_port'..."; |
13 | $result = socket_connect($socket, $address, $service_port); |
14 | if($result === false) { |
15 | echo "socket_connect() failed.\nReason: ($result) " . socket_strerror(socket_last_error($socket)) . "\n"; |
19 | $in = "HEAD / http/1.1\r\n"; |
20 | $in .= "HOST: localhost \r\n"; |
21 | $in .= "Connection: close\r\n\r\n"; |
23 | echo "sending http head request ..."; |
24 | socket_write($socket, $in, strlen($in)); |
26 | echo "Reading response:\n\n"; |
27 | while ($out = socket_read($socket, 8192)) { |
30 | echo "closeing socket.."; |
31 | socket_close($socket); |
执行结果如下：
server:
client:
