title: How to use substr but keep <br> in textarea
body: <p>So I've created a post function, but when I want to display the post on the front page, it should only show the first 200 letters as well as keeping all breaks the user made in the textarea. 
  What I am doing is the following:</p>
  
  <pre><code>substr($row["content"], 0, 200);
  </code></pre>
  
  <p>and this displays the content just fine, but it lets out all breaks that the user makes. </p>
