Use PHP parsing to write out contents between tags

I'm trying to "echo" the contents inside my "<span>" tag to the page using the getArticles function below.   It doesn't seem to want to write it out.    The function and only part of the HTML are below.   What am I doing wrong?


// HTML
<span class='clr2 b'>My Test</span>
**************************************************************
// FUNCTION
function getArticles($page) {  

    global $articles;  
 
    $html = new simple_html_dom();  
    $html->load_file($page);  
      //echo $html;
      
      $items = $html->find("span[class=clr2 b]");  

      foreach($items as $post) {

            # remember comments count as nodes
            // outertext
            // innertext
            // plaintext
            $articles[] = array($post->children(0)->outertext);

                        
      }
      
    foreach($articles as $item) {
        echo $item[0];

    }      
  }

I'm not sure why you are doing all of that.  I just put it in the page where I need it.
<span class='clr2 b'><?php echo $article; ?></span>

It's because I don't have direct access to the page, and I'm just trying to get used to handling a parser, so I don't have a choice--the data is already written out to the page.

Nothing....Here's the full code:

// TEST.HTML
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Untitled Document</title>
</head>
<body>
<span class='clr2 b'>My Test</span>
</body>
</html>


// INDEX.HTML
include('simple_html_dom.php');

$articles = array();
getArticles('test.html');


// SIMPLE_HTML_DOM.PHP -- THIS PAGE DOES WORK, I DIDN'T INCLUDE ALL OF THE CODE.   I
function getArticlesCars($page) {  

    global $articles;  
 
    $html = new simple_html_dom();  
    $html->load_file($page);  
      
      $items = $html->find("span[class=clr2 b]");  

      foreach($items as $post) {

            # remember comments count as nodes
            // outertext
            // innertext
            // plaintext
            $articles[] = array($post->children(0)->outertext);            
      }
      
    foreach($articles as $item) {
        echo $item[0];
    }      
  }
