如何在PHP中解析HTML？

尝试查看PHP简单HTML DOM解析器

它具有类似于jQuery的出色语法，因此您可以轻松按ID或类选择所需的任何元素

// include/require the simple html dom parser file$html_string = '    <p >        <span >Chapter 1</span>    </p>    <p >        <span >This is chapter 1</span>    </p>    <p >        <span >Chapter 2</span>    </p>    <p >        <span >This is chapter 2</span>    </p>    <p >        <span >Chapter 3</span>    </p>    <p >        <span >This is chapter 3</span>    </p>';$html = str_get_html($html_string);foreach($html->find('span') as $element) {    if ($element->class === 'Heading1-H') {        $heading[] = $element->innertext;    }else if($element->class === 'Normal-H') {        $content[] = $element->innertext;    }}
