title: PHP get month and year from a value such as 43556
body: <p>I have a field in the database called "GROWTH_SALES_MONTHSTART" which has a value 43556. What is the right way to get the month and year from this in PHP?</p>
  
  <p><code>strtotime( "43556")</code> gives <code>bool(false)</code>.</p>
  
  <p>EDIT:
  I tried the following but the date is not coming up right.</p>
  
  <pre><code>$tt = date( 'M-y', 43556 ) ;
  var_dump( $tt );
  </code></pre>
  
  <p>The actual date which I should receive is Apr-19 while I am getting Jan-70. Am I missing something?</p>
  
  <p>I am pulling the value (43556) from a CSV.</p>
