Question

I want to query a collection and get documents which have created less than 3 hours ago.

$realtime = date("Y-m-d H:i:s");
$mongotime = New Mongodate(strtotime($realtime));

$mongotime = $mongotime - 3 hours; //PSEUDOCODE
$some_condition = array('time' => array('$lt'=>$mongotime) );

$result = $db->collection->find( $some_condition );

Is there an effective way to put

$some_condition

part without using IF statement in PHP?

Answer 1

I have found the solution.

$diff = 60 * 60 * 3; //3 hours in seconds

$mongotime = New Mongodate(time()-$diff);

$condition = array('time' => array('$lt'=>$mongotime) );

$result = $db->collection->find( $condition );
