如何使用PHP从另一个PHP文件中读取html文件中的特定元素

How to read an html element by using id which is completely present in an another html file using php. I tried include but it loads all the content in that file and displayed in the browser but i just need to load only one tag.

file1.html

<body>
   <h3 id="title">Title</h3>
   <p> Some content about the title </>
</body>

file2.php

<?PHP

   #read h3 element using id and display

?>

    Simplest solution is to load the file ( file_get_contents ) and parse it using the DOM.

    PHP Dom Document : http://php.net/manual/en/domdocument.loadhtml.php

    The class has a getElementById method : http://php.net/manual/en/domdocument.getelementbyid.php

    file1.html

    <body>
      <h3 id="title">Title</h3>
      <p> Some content about the title </>
    </body>
    

    file2.php

    <?PHP
      $doc = new DOMDocument();
      $doc->loadHTMLFile("file1.html");
      $title = $doc->getElementById("title");
      echo $title->nodeValue;
    ?>
