Swoole是一个高性能的PHP异步网络通信引擎,它提供了异步TCP/UDP网络通信、异步文件读写、异步MySQL、异步Redis、消息队列等功能。利用Swoole框架开发高性能服务,可以从以下几个方面入手:
pecl install swoole
# 或者
git clone https://github.com/swoole/swoole-src.git
cd swoole-src
phpize
./configure
make && make install
extension=swoole.so
<?php
use Swoole\Server;
$server = new Server("127.0.0.1", 9501);
$server->on('Start', function (Server $server) {
echo "Swoole server started at http://127.0.0.1:9501\n";
});
$server->on('Receive', function (Server $server, $fd, $reactor_id, $data) {
$server->send($fd, "Server: " . $data);
});
$server->start();
?>
<?php
use Swoole\Server;
$server = new Server("127.0.0.1", 9501);
$server->on('Start', function (Server $server) {
echo "Swoole server started at http://127.0.0.1:9501\n";
});
$server->on('Receive', function (Server $server, $fd, $reactor_id, $data) {
$server->async(function () use ($server, $fd, $data) {
echo "Server: " . $data . PHP_EOL;
});
});
$server->start();
?>
<?php
use Swoole\Server;
use Swoole\Coroutine;
$server = new Server("127.0.0.1", 9501);
$server->on('Start', function (Server $server) {
echo "Swoole server started at http://127.0.0.1:9501\n";
});
$server->on('Receive', function (Server $server, $fd, $reactor_id, $data) {
Coroutine::create(function () use ($server, $fd, $data) {
echo "Server: " . $data . PHP_EOL;
});
});
$server->start();
?>
<?php
use Swoole\Server;
use Swoole\Coroutine;
use Swoole\MySQL;
$server = new Server("127.0.0.1", 9501);
$server->on('Start', function (Server $server) {
echo "Swoole server started at http://127.0.0.1:9501\n";
});
$server->on('Receive', function (Server $server, $fd, $reactor_id, $data) {
Coroutine::create(function () use ($server, $fd, $data) {
$mysql = new MySQL();
$mysql->connect(['host' => '127.0.0.1', 'user' => 'root', 'password' => '', 'database' => 'test']);
$result = $mysql->query('SELECT * FROM users');
var_dump($result);
});
});
$server->start();
?>
<?php
use Swoole\Server;
use Swoole\Coroutine;
use Swoole\Redis;
$server = new Server("127.0.0.1", 9501);
$server->on('Start', function (Server $server) {
echo "Swoole server started at http://127.0.0.1:9501\n";
});
$server->on('Receive', function (Server $server, $fd, $reactor_id, $data) {
Coroutine::create(function () use ($server, $fd, $data) {
$redis = new Redis();
$redis->connect(['host' => '127.0.0.1', 'port' => 6379]);
$redis->set('key', 'value');
$value = $redis->get('key');
echo "Redis value: " . $value . PHP_EOL;
});
});
$server->start();
?>
通过以上步骤,你可以利用Swoole框架开发出高性能的服务。Swoole的强大功能和优化特性使其成为处理高并发、实时性要求高的应用的理想选择。
