title: Year and week to date in php
body: <p>I have two pieces of information extracted from a MySQL database, the <strong>year</strong>(2009, 2010, ect) and the <strong>week</strong> (1-52). And I need to convert it in to a date start and date end.. </p>
  
  <p>For example: </p>
  
  <pre><code>Year=2010, Week=1 would be (Friday, Jan 1st, 2010) - (Sunday, Jan 3rd, 2010)
  Year=2010, Week=33 would be (Monday, Aug 16th, 2010) - (Sunday, Aug 22nd, 2010)
  Year=2010, Week=34 would be (Monday, Aug 23rd, 2010) - (Sunday, Aug 29th, 2010)
  </code></pre>
  
  <p>How would I go about doing that in php ?</p>
