如何安装PHP扩展libzookeeper
PHP扩展libzookeeper(https://github.com/Timandes/libzookeeper)主要用于使用PHP代码连接Zookeeper集群。
扩展对原Zookeeper C Client(https://zookeeper.apache.org/)的功能进行了简化,强调简单性与易用性。
同时,本着开放的精神,允许更多的参与到Zookeeper的开发与使用当中。
libzookeeper扩展依赖于Zookeeper C Client,后者包含在Zookeeper的安装包中,具体安装方法参看:https://zookeeper.apache.org/doc/r3.5.0-alpha/zookeeperProgrammers.html#Installation。
下面介绍libzookeeper的安装步骤(以v0.3.1为例):
1)下载并解压缩安装包:
wget https://github.com/Timandes/libzookeeper/archive/v0.3.1.tar.gz libzookeeper-0.3.1.tar.gz
tar xvf libzookeeper-0.3.1.tar.gz
2)编译并安装扩展:
cd libzookeeper-0.3.1
phpize
./configure --with-libzookeeper=/path/to/zookeeper_c_client
make
make install
其中,/path/to/zookeeper_c_client代表已安装好的Zookeeper C Client的路径。
3)编辑php.ini,插入如下代码行:
extension=libzookeeper.so
4)如果使用PHP-FPM,则需要重启该服务:
service php-fpm restart
5)检查扩展加载情况:
php -m | grep libzookeeper

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,

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.

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.
