HomeBackend DevelopmentPHP TutorialPHP伪静态写法附代码_php技巧

比如这个网页
http://www.jb51.net/soft.php/1,100,8630.html

其实处理的脚本是soft.php 参数为1,100,8630

相当于soft.php?a=1&b=1=100&c=8630 只不过这样的URL太难记。搜索引擎也不喜欢。

真静态只是完全生成了HTML。

客户端访问的时候直接输出。不用脚本解释。在流量非常大的时候(比如每天有上百万的访问量的时候)会起到很好的效果。也就是说服务器端实实在在的存在这个HTML页面。

当然在你网站的流量没有那么大的时候。URL重写是最好的方法(个人观点,大流量的时候可以考虑负载均衡了。同样没有关系)

附URL重写的方法有很多种,APACHE,IISREWRITE。甚至PHP脚本都可以直接处理。比如上例中就是PHP脚本直接处理(该方法好处是大流量的时候直接减轻WEB伺服器的压力。PS:同样也是个人观点:

================================================

下面以程序为例讲一下PHP伪静态的程序实现方法,其实这方法我之前已经有在其它论坛社区发过

程序为例:

http://www.jb51.net/soft.php/1,100,8630.html

复制代码 代码如下:

//利用server变量 取得PATH_INFO信息 该例中为 /1,100,8630.html   也就是执行脚本名后面的部分
if(@$path_info =$_SERVER["PATH_INFO"]){
//正则匹配一下参数
if(preg_match("/\/(\d+),(\d+),(\d+)\.html/si",$path_info,$arr_path)){
$gid     =intval($arr_path[1]); //取得值 1
$sid     =intval($arr_path[2]);   //取得值100
$softid   =intval($arr_path[3]);   //取得值8630
}else die("Path:Error!");
//相当于soft.php?gid=1&sid=100&softid=8630 
}else die('Path:Nothing!');
//就是这么简单了。~)

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
