两个日期之间的PHP查询？

Question

I am trying to set a table up to display out of date tests. So, I have a test that is dated 28/01/2014 and the next test is due on 28/01/2015. As of today's date, this is out of date.

My query looks like the following:

$expiry = date("Y-m-d");
$queryout = "SELECT appliances.*, tests.* FROM (appliances LEFT JOIN tests  
             ON appliances.ID = tests.Appliance) WHERE Cli_ID = '$useractiveid' 
             AND `Next Test Due` BETWEEN `Date Tested` AND  '" . $expiry . "'";

I want the query to find tests that are out of date where the Next Test Due is out of date.

Here is my answer based on my comments:

$expiry = date("Y-m-d");
$queryout = "SELECT appliances.*, tests.* FROM (appliances LEFT JOIN tests  
             ON appliances.ID = tests.Appliance) WHERE Cli_ID = '$useractiveid' 
             AND where Next Test Due < '" . $expiry . "'";
