使用PHP在html的嵌套标签中获取每个标签中的标签值

Question

I'm working in code that get all tags values "Text only" from html file. But if any tag has nested tags it will go inside Childs and get the the tag value that hasn't a child. I tried this one but it has a bit of missing

php code:

$dochtml = new DOMDocument();
$dochtml->loadHTMLFile("index2.html");
$nodes = $dochtml ->getElementsByTagName("a"); 
gettagsvalue($nodes);
  function gettagsvalue($nodes){
    if($nodes->length != 0){
      for ($i=0;$i<$nodes->length;$i++){
        foreach ($tags=["h1","h2","h3","h4","h5","h6","h7","a","img","li","span","p","pre","i","strong","div","ul"] as $tag){  
          if($nodes->item($i)->getElementsByTagName($tag)->length != 0){
            if ($nodes->item($i)->getElementsByTagName($tag)->length == 1){
              echo "here"."<br><br><br> $tag";
              echo "<pre>" ;print_r($nodes->item($i)->getElementsByTagName($tag)->item(0));echo "</pre>" ;             
            }else{
              echo "there"."<br><br><br> $tag";
              gettagsvalue($nodes->item($i)->getElementsByTagName($tag));
              // echo "$tag <br><br><br>";
            }
            // print_r($nodes->item($i)->getElementsByTagName($tag));echo "<br>"; 
          }        
      }
    }
  }
}

i expected to get

"Green" "valley"

HTML:

<a href="index.html" id="aaaaaaaaaaaa2015284957">
    <img src="images/logo.png" width="50px" height="50px" id="imgaaaaaaaaaaimg732756221">
    <span>Green</span>
    <span id="spanaaaaaaaaaaspan1106733773">Valley</span>
</a>

Did you consider using textContent property? This should concatenate text nodes of all nested nodes. See php domdocument read element inner text and PHP DOM textContent vs nodeValue? for more details.
