Question

How can I compare this datetime from the MySQL database with now?

I sent the date in the database record using the MySQL function now() and was trying to detect records that were more than 30 days old.

if (date_diff($myrow["LastLogin"], time()) > -30) {
  }

$myrow["LastLogin"] does contain a valid value since i see it as text. confirmed in the database it’s a “datetime” type.

here’s more of the code.

if ($myrow = mysql_fetch_array($result_set)) { 

  do {
      if (date_diff($myrow["LastLogin"], getdate()) > -30) {
        echo "<tr>";
        echo "<td>" . $myrow["PCName"] . '&nbsp;</td>';
        echo "<td>" . $myrow["LastLogin"] . '&nbsp;</td>';
        echo "</tr>\n";
      }
  } while ($myrow = mysql_fetch_array($result_set));  
}

thank you!

Do it in your query, not in the code.

SELECT * FROM myTable WHERE LastLogin < DATE_SUB(NOW(), INTERVAL 30 DAY)
