PHP怎么获取url里的自定义参数,
比如:
- http://www.xxx.com/cba/index.php
- http://www.xxx.com/abc/index.php
- http://www.xxx.com/bbb/index.php
分别出来的值是:
- cba
- abc
- bbb
即
http://www.xxx.com/{shop}/index.php
需要获取shop这个变量

apache大概这样配置
<code>AliasMatch ^/(匹配你参数的正则表达式)/index.php /path/to/process.php?arg=$1 </code>
然后在process.php文件里$_GET['arg'] 就是
告诉一种用过的愚蠢的办法吧$_SERVER['PHP_SELF']
取出,然后正则,详情看以看看这个链接
外加,一般PHP程序都是用框架写的把,那样的话你可以去他的文档找他定义的常量即可,实在没有就是上面的
方案1. 使用服务器的URI重写功能,参考@zonxin的答案
方案2. 在PHP中去解析URL,注意应该使用$_SERVER['REQUEST_URI']
,例如:
<code> if (preg_match('|^/([^/]+)/index.php|', $_SERVER['REQUEST_URI'], $matches)){ list(, $shop) = $matches; echo $shop; // => 你期望的shop这个变量 } </code>
b.t.w. 关于REQUEST_URI和PHP_SELF的区别,请参考这篇讨论
.htaccess重写url
<code>isset($_SERVER['PATH_INFO'])?explode('/',my_addslashes(ltrim(trim($_SERVER['PATH_INFO']),'/'))) </code>
可以使用PATH_INFO获取,不过不建议这么做了,现在的框架都是使用query_string
获取PATH_INFO,用正则匹配出来
<code>preg_match('/\/(.*)\/index.php/',$_SERVER['PATH_INFO'],$match); var_dump($match[1]); </code>

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.

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.

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),

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
