HomeBackend DevelopmentPHP TutorialPHP正则表达式提取超链接及其标题

有这么一段HTML,比较不规则的,如果要提取其中的链接地址和链接名称,怎么弄?

//HTML
$str = ''歌曲列表
中文金曲榜

• 轻音乐 '';

利用正则表达式是最简单的,其它的办法,偶米去想。。。

$pat = ''/(.*?)/i'';
preg_match_all($pat, $str, $m);

输出方法:

print_r($m[2]);
print_r($m[4]);

或者:
for($i=0;$i    echo ''

  • ''.$m[4][$i].'''';
    }

    显示结果是:

    Array ( [0] => http://list.mp3.baidu.com/song/A.htm?top8 [1] => http://list.mp3.baidu.com/list/bangping.html [2] => qingyinyue.html?top19 ) Array ( [0] => 歌曲列表 [1] => 中文金曲榜 [2] => 轻音乐 )

    于是,我们要采集某个网站的标题及链接地址方法就出来了。。。自己套用吧。。。

    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.

    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.
