php实现伪静态
伪静态主要是为了SEO而存在的一种技术,又名URL重写。至于为什么要实现伪静态这里就不详细解释了。一般实现伪静态技术都是使用apache服务的mod_rewrite功能,通过在名为.htaccess的文件里面书写一些rewrite规则的正则来实现URL重写技术,这种技术本篇不做详解,下面以程序为例主要讲一下利用PHP程序实现伪静态的方法。下面就是实现伪静态的php函数
</p> <p><!--?php</p-->/*<br /> 功能:PHP伪静态化页面的实现<br /> */<br /> function mod_rewrite(){<br /> global $_GET;<br /> $nav=$_SERVER['REQUEST_URI'];<br /> $script_name=$_SERVER['SCRIPT_NAME'];<br /> $nav=substr(ereg_replace("^$script_name",'',urldecode($nav)),1);<br /> $nav=preg_replace('/.htm(l){0,1}$/i','',$nav);//这句是去掉尾部的.html或.htm<br /> $vars=strpos($nav,'/')!==false?explode('/',$nav):array();<br /> $nav=count($vars);<br /> if($nav){<br /> for($i=0;$i<$nav;$i+=2){<br /> $_GET[$vars[$i]]=$vars[$i+1];<br /> }<br /> }<br /> return $_GET;</p> <p>}
例如对于如下这样的链接地址:
http://www.scutephp.com/index.php/controller/user/action/login.html
经过函数处理后,我们就可以得到他的链接原型了:
http://www.scutephp.com/index.php?controller=user&action=login
该函数的具体用法如下:
</p> <p><!--?php</p-->mod_rewrite();<br /> $yearn=$_GET["controller"];//结果为'user'<br /> $action=$_GET["action"];//结果为'login'<br /> <br /> echo '</p> <pre class="brush:php;toolbar:false"> ';
print_r($_GET);
至于具体情况,读者可根据自己的情况来吧,这里就不多说了。

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.
