mac osx 更改自带php版本
原来在windows上面做开发的时候一直实用zendstudio＋zenddebugger来调试代码的，但是发现zenddebugger的php版本只到5.3就没有后面的了。 听说是集成到zend server上面了。扯远了，不说那个了。既然php5.4没办法实用zenddebugger了，那能不能把osx自带的php5.

听说是集成到zend server上面了。扯远了，不说那个了。既然php5.4没办法实用zenddebugger了，那能不能把osx自带的php5.4换成php5.3呢？
马上google了下，发现还真有，而且很简单。一行代码搞定
curl -s http://php-osx.liip.ch/install.sh | bash -s 5.3
如果直接cil方式执行php的话，发现还是php5.4版本的。下面我们可以把默认的php换成我们的5.3版本的
#把默认版本备份，如果不想备份，直接删除也行
mv /usr/bin/php /usr/bin/php-php-5.4.17
ln -s /usr/local/php5-5.3.28-20140112-174528/bin/php /usr/bin/php
终端执行 php -v 已经显示php5.3的了

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.

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,
