如何使用PHP Simple HTML dom获取此文本？

问题描述：

Assuming I have this HTML Code in an HTML source:

<div class="info">
    <p><span class="strong">Score</span>4.32/5</p>
    <p><span class="strong">Type</span>TV</p>
    <p><span class="strong">Episodes</span>13</p>
    <p><span class="strong">Status</span>Ongoing</p>
    <p><span class="strong">Aired</span>Oct 3, 2015 - Dec 26, 2015</p>
    <p><span class="strong">Age</span>PG-13 - Teens 13 or older</p>
</div>

How do I use the PHP Simple HTML dom to get the text 4.32 from above? I tried

foreach($info_html->find('.strong') as $library) {
    $rating = $library->innertext;
    var_dump($rating);
}

But that only gives me the text "score", but I want 4.32.

假设我在HTML源代码中有这个HTML代码： p>

 ＆lt; div class =“info”＆gt; 
＆lt; p＆gt;＆lt; span class =“strong”＆gt;得分＆lt; / span＆gt; 4.32 / 5＆lt; / p＆gt; 
＆lt; p＆gt;＆lt; span class =  “strong”＆gt;类型＆lt; / span＆gt;电视＆lt; / p＆gt; 
＆lt; p＆gt;＆lt; span class =“strong”＆gt;集数＆lt; / span＆gt; 13＆lt; / p＆gt; 
＆lt; p＆gt;＆lt; span  class =“strong”＆gt;状态＆lt; / span＆gt;正在进行＆lt; / p＆gt; 
＆lt; p＆gt;＆lt; span class =“strong”＆gt;已播出＆lt; / span＆gt; 2015年10月3日 -  2015年12月26日＆lt; / p＆gt  ; 
＆lt; p＆gt;＆lt; span class =“strong”＆gt;年龄＆lt; / span＆gt; PG-13  - 青少年13岁或以上＆lt; / p＆gt; 
＆lt; / div＆gt; 
  code>  pre>  
 
 如何使用PHP Simple HTML dom从上面获取文本4.32？
我试过 p> 
 
 
  foreach（$ info_html-＆gt; find（  '.strong'）作为$ library）{
 $ rating = $ library-＆gt; innertext; 
 var_dump（$ rating）; 
} 
  code>  pre> 
 
  但这只给了我文本“得分”，但我想要4.32。 p> 
  div>

答

Maybe this will give you the result you are looking for:

foreach($info_html->find('div.info p') as $library) {
    $rating = $library->find('text', 1)->innertext;
    var_dump($rating);
}

答

Or you can find < p > tag elements first:

foreach($info_html->find('p') as $library) {
        $rating = $library->find('text', 1)->plaintext;
        var_dump($rating);
}
