title: Get next monday date in PHP (including today)
body: <p>I am creating a PHP page that based on a date, will get the date of the next Monday.</p>
  
  <p>A snippet of my code is below - I am obtaining the next monday date using the DateTime and modify methods, but what I need to include is that if today's date is Monday, I want to select that (as it is only selecting the next monday, not including today.</p>
  
  <pre><code>$startDate = new DateTime();
  $startDate-&gt;modify('next monday')-&gt;format('d-m-Y');
  </code></pre>
  
  <p>How can I change this so that if today is a Monday, it uses today's date and not the next Monday after it?</p>
