title: The best way to get the first and last day of last month?
body: <p>I'm looking for the best way to get the first and the last  day of a last month. I use them for make SQL queries to get stats of last month.</p>
  
  <p>I think that this is the best way, more optimized but not more comprensive, anyone have another way to do the same? </p>
  
  <pre><code>    $month_ini = date("Y-m-d", mktime(0, 0, 0, date("m", strtotime("-1 month")), 1, date("Y", strtotime("-1 month"))));
  
      $month_end = date("Y-m-d", mktime(0, 0, 0, date("m", strtotime("-1 month")), date("t", strtotime("-1 month")), date("Y", strtotime("-1 month"))));
  </code></pre>
  
  <p>Thanks!!</p>
