title: PHP strtotime() different results of monday this week
body: <p>I have a problem getting the date of monday in the current week.</p>
  
  <pre><code>echo date('Y-m-d',strtotime('monday this week'));
  </code></pre>
  
  <p>When I'm running the above code on my local machine (PHP 5.3) it outputs correctly '2011-03-07', but the same code on my server (PHP 5.2) outputs '2011-03-14' (that's monday next week).</p>
  
  <p>I've tried to run date('W') on both machines and I get the same result (10).</p>
  
  <p>Edit: Any ideas how get this work correctly?</p>
  
  <p>Thanks in advance.</p>
