删除在PHP中留下文本内容的html元素

嗨,请任何人给我一个解决方案.我想从这个html中删除整个div和span,除了< span>中的4.请任何人

<div class=\"fivestar-widget-static fivestar-widget-static-Vote fivestar-widget-static-5 clear-block\">
  <div class=\"star star-1 star-odd star-first\">
    <span class=\"on\">4</span>
  </div>
  <div class=\"star star-2 star-even\">
    <span class=\"on\"></span>
  </div>
  <div class=\"star star-3 star-odd\">
    <span class=\"on\"></span>
  </div>
  <div class=\"star star-4 star-even\">
    <span class=\"on\"></span>
  </div>
  <div class=\"star star-5 star-odd star-last\">
    <span class=\"off\"></span>
  </div>
</div>

解决方法

要删除HTML标记但保留其文本内容,您只需使用strip_tags：

$string = "<div>Hello</div> <span>Hi</span> Other text";
$string = strip_tags($string);

// You'll probably also want to trim the results 
// to remove extraneous whitespace
$string = trim($string);

这将导致“Hello Hi Other text”
