//2:获取远程网页的简介

初学PHP,想要获取远程网站的标题及简介,网上查了好几天写出来的结果,勉强能达到想要的结果,获取速度有点慢,感觉代码很乱,不知道有没有更好的方法,

你可以合成一个函数啊,那就应该很快了。
你这分析一个页面要获取多少次阿得

你看你每个函数里都用file_get_contents。当然慢啦。
应该只有1个函数用来file_get_contents获取内容,然后将内容传给每个函数来匹配结果!
谢谢大家的回答 正好4人40分 回答都一样 确实file_get_contents整了多次 因为初学 改起来可能费劲

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.
