php domdocument read element inner text

问题

I'm new to php so please forgive the simple question:

How do I extract the text from an element?

     <span id="myElement">Some text I want to read</span>

I have this for a start:

<?php
      $data = $dom->getElementById("myElement");
      $html = $dom->saveHTML($data);

But then? What is the correct instruction?

回答1:

To get the text that an element contains, you need the textContent property:

$text = $data->textContent;
