php正则匹配嵌套
php新手, 最近用php写正则匹配 遇到了一个问题
楼主用 preg_match 函数 在php正则匹配网页
即获取
这时如果遇到 div 嵌套
<div id="目标id"><br /> <!--中间有不确定数目的<div>标签--><br /> <div><br /> </div> <!--楼主的方法在这里匹配结束--><br /> <div><br /> </div><br /> <!--.......--><br /></div>
就会在第一个
求问php里怎么样解决?。。
或者有没有现成的可以通过 标签 id来获取标签内所有内容的函数 或者库?
楼主更加希望php有函数或者库可以一下子拿到整个标签内容 而不要自己手动些正则,平时用python和java比较多,比较懒。。
刚接触php 不太了解 如果能推荐一些比较好的学习网站不甚感激。

$s =<<< TXT<br /><div id="tid"><br /> <!--中间有不确定数目的<div>标签--><br /> <div><br /> </div> <!--楼主的方法在这里匹配结束--><br /> <div><br /> </div><br /> <!--.......--><br /></div><br />TXT;<br />$s = iconv('gbk', 'utf-8', $s); //如果是 utf-8 的就不需要了<br /><br />require('phpQuery.php');<br />$doc = phpQuery::newDocument($s);<br />//echo $doc->find('#tid')->html(); //可以这样写<br />echo pq('#tid')->html(); //也可以这样写<br />
<!--中间有不确定数目的<div>标签--><br /> <div><br /> </div> <!--楼主的方法在这里匹配结束--><br /> <div><br /> </div><br /> <!--.......-->
用正则也可以,但每次都要绞尽脑汁,有点得不偿失
而用 phpQuery 类则是只需会用 js 的 jQuery 就行了

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

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.
