如何使用php简单html dom解析器获取外部url 假设上面的html文件名为“index.html”

您要查阅手册：

<div id="lyrics">
  <img />
  <span id="line_31" class="line line-s">En medio de este tropico mortal</span
  <br>
  <span id="line_32" class="line line-s">Roots and creation, come again!</span>
  <br> 
  <span id="line_33" class="line line-s">So mi guardian, mi guardian mi lift up di plan</span>
  <span id="line_34" class="line line-s">Now everybody a go' do dis one</span>
  <span id="line_35" class="line line-s">Like in down di Caribbean</span>
  <span id="line_36" class="line line-s">San Andrés, Providence Island</span>
  <br>
</div>

$html = file_get_html("index.html");
$element = $html->find('div#lyrics');
$result = $element->innertext;
