title: Split string after every five words
body: <p>I want to split a string after every five words.</p>
  
  <p><strong>Example</strong></p>
  
  <blockquote>
    <p>There is something to type here. This is an example text</p>
  </blockquote>
  
  <p><strong>Output</strong></p>
  
  <pre><code>There is something to type
  here. This is an example
  text
  </code></pre>
  
  <p>How can this be done using <code>preg_split()</code>? Or is there any way to wrap text in PHP GD?</p>
