PHP异步操作(swoole, gearman)
PHP异步操作
废话不说直接进入正题:
应用场景:
业务逻辑中经常会出现发送信息,发送邮件,记录日志等等,这个时候用异步再好不过了,用户直接的体验就是:使用的贼流畅~~
使用技术:
1.gearman : 这个不仅仅支持PHP了其他语言也支持
2.swoole : 有PHP的扩展,用起来更方便
NOTE:感觉上 gearman = swoole + 异步队列;
不同点:
1.gearman有个队列专门用来存储发送过来的异步请求,即使worker挂了,重启以后,照样也能将没有处理的请求处理.swoole在这点上没有专门的处理
2.swoole的使用安装更为方便,使用C语言写的PHP扩展,性能测试了下,杠杠的,使用到目前为止没有什么问题,gearman的安装比较麻烦,网上文章一大堆,试了很多都没用,后来到了gearman的官网才解决掉.
3.gearman的历史比较悠久,使用场景很丰富,有详细的文档,业务量不算很大的使用,非常稳定.swoole是中国人开发的(支持国产),有很多大型公司在使用,
详细的gearman安装文档:
yum -y install libgearmanyum install libgearman-develwget http://pecl.php.net/get/gearman-1.1.2.tgztar -zxvf gearman-1.1.2.tgzcd gearman-1.1.2/data/apps/php/bin/phpize./configure --prefix=/data/apps/phpgearman --with-php-config=/data/apps/php/bin/php-configmake&& make installvim /data/apps/php/etc/php.ini增加extension=gearman.so测试vim worker.php <?php$worker= new GearmanWorker();$worker->addServer();$worker->addFunction("reverse", "my_reverse_function");while ($worker->work());function my_reverse_function($job){ return strrev($job->workload());}?>vim client.php<?php$client= new GearmanClient();$client->addServer();print $client->do("reverse", "Hello World!");?>php client.php!dlroW olleH
安装swoole的PHP扩展:
wget http://pecl.php.net/get/swoole-1.7.17.tgztar -zxvf swoole-1.7.17.tgzcd swoole-1.7.17phpize./configuremake && make install

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.
