title: Crop string after 2nd full stop
body: <p>In PHP, I'd like to crop the following sentence:</p>
  
  <p>"Test 1. Test 2. Test 3."</p>
  
  <p>and transform this into 2 strings:</p>
  
  <p><strong>"Test 1. Test 2."</strong> and <strong>"Test 3."</strong></p>
  
  <p>How do I achieve this?</p>
  
  <p>Do I use strpos?</p>
  
  <p>Many thanks for any pointers.</p>
