本文实例讲述了php基于 swoole 实现的异步处理任务功能。分享给大家供大家参考,具体如下:
安装swoole:
下载官方swoole压缩包,解压进入目录

|
$ cd swoole # 进入 swoole 目录
$ phpize
$ . /configure --with-php-config= /usr/local/php/bin/php-config #注意查看服务器上是否有这个路径
$ make && make install
|
修改php.in文件
1
|
vi /usr/local/php/lib/php .ini
|
增加如下内容
1
|
extension = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20160303/swoole.so" // 版本不同路径可能不同
|
保存后重启php-fpm
1
|
$ /etc/init .d /php-fpm restart
|
php -m 命令查看是否添加成功 成功则会看到有swoole模块
1
|
$ php -m
|
服务端作为守护进程监控任务,新建server.php:

<?php
$serv = new Swoole\Server( "127.0.0.1" , 9502);
$serv ->set( array ( 'task_worker_num' => 4));
$serv ->on( 'Receive' , function ( $serv , $fd , $from_id , $data ) {
$task_id = $serv ->task( "Async" );
echo "Dispath AsyncTask: id=$task_id\n" ;
});
$serv ->on( 'Task' , function ( $serv , $task_id , $from_id , $data ) {
echo "New AsyncTask[id=$task_id]" .PHP_EOL;
$serv ->finish( "$data -> OK" );
});
$serv ->on( 'Finish' , function ( $serv , $task_id , $data ) {
echo "AsyncTask[$task_id] Finish: $data" .PHP_EOL;
});
$serv ->start();
|
用命令行模式打开
1
|
php server.php
|
新建一个client.php

<?php
$client = new swoole_client(SWOOLE_SOCK_TCP, SWOOLE_SOCK_ASYNC);
$client ->on( "connect" , function (swoole_client $cli ) {
$cli ->send( "GET / HTTP/1.1\r\n\r\n" );
});
$client ->on( "receive" , function (swoole_client $cli , $data ){
echo "Receive: $data" ;
$cli ->send( str_repeat ( 'A' , 100). "\n" );
sleep(1);
});
$client ->on( "error" , function (swoole_client $cli ){
echo "error\n" ;
});
$client ->on( "close" , function (swoole_client $cli ){
echo "Connection close\n" ;
});
$client ->connect( '127.0.0.1' , 9502);

打开一个新的窗口命令行执行
1
|
php client.php
|
执行完后会发现在server.php的窗口就会有信息输出
希望本文所述对大家PHP程序设计有所帮助。
