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; }}
