如何使用PHP获取h1的内容以在Twitter数据文本参数中使用

Question

Here is the contents of my twitter.php include:

<?php
$tags = get_meta_tags();
echo $tags;
$dynamic_tweet_text="Episode Title by @OurCityOurStory: http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";
?>

<a href="https://twitter.com/share" class="twitter-share-button" rel="canonical" data-text="<?php print $dynamic_tweet_text ?>">Tweet</a>
<script>!function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs");</script>

The part that reads "Episode Title" of $dynamic_tweet_text needs to be dynamic. I need to grab it from the h1#title .

How do I do this? It has to be done server-side due to the way Twitter's JS works and I'm not great with PHP.

If you are familiar with jquery you can use library which allows you to get content by selectors, ids, elements, etc. - just like in jquery. Check this out http://simplehtmldom.sourceforge.net/
