这篇文章主要介绍了php使用socket编程的示例，大家参考使用吧
2个php测试文件
server.php
代码如下:
<?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);
$talkback = "收到的信息:$bufn";
echo $talkback;
if(++$count >= 5){
break;
};
}
//echo $buf;
socket_close($msgsock);
} while (true);
socket_close($sock);
?>
client.php
代码如下:
<?php
error_reporting(E_ALL);
set_time_limit(0);
echo "<h2>TCP/IP Connection</h2>n";
$port = 1935;
$ip = "127.0.0.1";
/*
+-------------------------------
* @socket连接整个过程
+-------------------------------
* @socket_create
* @socket_connect
* @socket_write
* @socket_read
* @socket_close
+--------------------------------
*/
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
if ($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($socket) . "n";
}else {
echo "发送到服务器信息成功！n";
echo "发送的内容为:<font color='red'>$in</font> <br>";
}
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
代码如下:
# /usr/local/php/bin/php /usr/local/apache2/htdocs/server.php
请求
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
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
代码如下:
extension=sockets.so
重启apache
代码如下:
# /usr/local/apache2/bin/apachectl restart
Windows下的配置
修改php.ini
代码如下:
extension=php_sockets.dll
重启apache
cmd下起2个
php的安装目录
代码如下:
C:/php/php.exe F:web/server.php
C:/php/php.exe F:web/client.php
