PHP table of contents HTML -

i have got php file uses include function import article. article php file. create table_of_contents() function, place inside file want contents list appear (like on wikipedia articles). function should scan article <h2> tags ids beginning "article-", , output list of these headings links.

eg:

<h1>article</h1> <?php table_of_contents() ?> <h2 id="article-intro">introduction</h2> <p>text</p> <h2>middle</h2> <p>text</p> <h2 id="article-conclusion">conclusion</h2> <p>text</p> 

would render

<h1>article</h1> <ul>     <li><a href="#article-intro">introduction</a></li>     <li><a href="#article-conclusion">conclusion</a></li> </ul> <h2 id="article-intro">introduction</h2> <p>text</p> <h2>middle</h2> <p>text</p> <h2 id="article-conclusion">conclusion</h2> <p>text</p> 

<h1>article</h1> <ul id="menu">  </ul> <h2 id="article-intro">introduction</h2> <p>text</p> <h2>middle</h2> <p>text</p> <h2 id="article-conclusion">conclusion</h2> <p>text</p>   <script> $('h2[id^="article-"]').each(function(){ $('#menu').append('<li><a href="#article-'+$(this).html()+'">'+$(this).html()+'</a></li>'); }); </script> 

i think work. don't forget include latest jquery.
