    Use strtotime() function to convert dates into unix timestamp. For example:

    
// Convert date to timestamp
$timestamp1 = strtotime('2009-03-28 12:00:00');
$timestamp2 = strtotime('2009-03-29 12:00:00');

// Get difference in seconds
$difference = $timestamp2 - $timestamp1;

// Get number of hours
$hours =  $difference / 3600; // 3600 is number of seconds in one hour

echo $hours;
