PHP Palm Pre HTML
$html = HtmlReplace($body, 0); //过滤
echo $html;//输出内容是:
<br> //编译成HTML:<pre class="brush:php;toolbar:false"> <br> <br> <br> /*************以上为背景*************/ <br> <br> $html = str_replace("<pre class="lang-js">","<pre class="brush:php;toolbar:false">",HtmlReplace($body, 0)) <br> <br> 这样替换后可以正常输出了,但是问题来了! <br> <br> 我要替换多个标签,比如: <span>,<ul>,<li>... <br> <br> 这样一个一个写,太傻了!有什么办法可以一次性定义替换需要的内容? <br> <br> 如: <br> <span> = <span> <br> <ul> = <ul> <br> <li> = <li> <br> <br> 新手 <br> <br> <br> <br> <h2 id="回复讨论-解决方案">回复讨论(解决方案)</h2> <p class="sougouAnswer"> echo htmlspecialchars_decode($html, ENT_QUOTES); </p> <p class="sougouAnswer"> #1是专门对付html标签的 <br> 另外还可以用数组和正则 </p> </li> </ul></span> </li> </ul></span>

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.
