PHP How to compare date and date?

I have this value from database:

'2009-1-1 00:00:00', okay, let me paste my code:

$fetch = mysql_fetch_assoc($result);
$db_value = $fetch['date'];//'2009-1-1 00:00:00'

$today = date('Y-m-d H:i:s'); // Todays date

If I want to compare the two values, what should I do:

if($db_value < $today){
    // Do something

or method 2, convert to strtotime:

if(strtotime($db_value) < strtotime($today)){
    // Do someting

Maybe my method is not correct, what should I use to compare 2 dates?


Probably , you can get the epoch value of the date using mktime function , then you could

compare the date's times stamp values easily . before that you parse first date string

into year, month , day , hours, minutes , seconds. then use mktime function

You should use the second one, because your db result is a string so it can't be used like that.

You can use simple PHP date class to compare dates. It makes comparison very easy.

For example:

$date = new simpleDate();
echo $date->set($date1)->compare($date2)->isBefore();

There are also useful other comparison methods in the library. Please check the tutorials page. Click here.
