title: Using strtotime to parse a date in the format d/m/Y
body: <p>This is my PHP code:</p>
  
  <pre><code>$g = "19/06/2013"; 
  echo $g." // ".date("Y/m/d", strtotime($g))
  </code></pre>
  
  <p>The output is this <code>19/06/2013 // 1970/01/01</code> instead of <code>19/06/2013 // 2013/06/19</code>.Why?</p>
