如何使用Simple HTML dom解析器回显innertext

HTML Source Code:

<div id="ctl00_ContentPlaceHolder_Middle_RatingSummary1_Rating1_RatingPanel">
<img id="ctl00_ContentPlaceHolder_Middle_RatingSummary1_Rating1_RatingImage" title="(2.5 / 5)  : Above Average" src="../../../../../images/net/common/stars/transparent/2.5.png" alt="(2.5 / 5)  : Above Average" style="border-width:0px;" />
<span id="ctl00_ContentPlaceHolder_Middle_RatingSummary1_Rating1_RatingText" class="text med strong">(2.5 / 5)  : Above Average</span>
<a id="ctl00_ContentPlaceHolder_Middle_RatingSummary1_Rating1_RatingHelp" class="help"></a>

I want Output like this:

(2.5 / 5)  : Above Average

I tried it, but not Getting it:

Php code:

$ratings = $html->find('div[id=ctl00_ContentPlaceHolder_Middle_RatingSummary1_Rating1_RatingPanel] span')->outertext;

echo "$ratings[0]"; 

First of all, if you write

echo "something_here"

You'll get as output

something_here

even if something_here is a variable. If you want to print a variable, don't put it inside ""

Now, instead of

$ratings = $html->find('div[id=...] span')->outertext;
echo "$ratings[0]";

Try doing

$ratings = $html->find('div[id=...] span');
echo $ratings[0]->outertext;

Besides, you probably want innertext instead of outertext
