Comparing two date in php

Question

I need to compare two dates

d1= 12-11-01(YY-MM-DD) and d2=2008-05-02(YYYY-MM-DD)

comparison d2 <= d1

It is not working as per requirement

Here please note that I need to compare dates with different date formats.

What is 12? what is 11? What is 01? Year, month, day? Month, day, year? Day, month, year?... No answer considers this. — Voitcus, Mar 28 '13 at 12:50
Can you reopen question Rikesh, tereško, dragon112, ircmaxell, Alexander as it is unique one? — Abhijit Shelar, Oct 11 '13 at 07:03

Try with:

$d1 = strtotime('12-11-01');
$d2 = strtotime('2008-05-02');

if ( $d2 <= $d1 ) {}

DateTime is better than strtotime() because it can account for timezones and daylight savings time

$dt1 = new DateTime('12-11-01');
$dt2 = new DateTime('2008-05-02');
if ( $dt2 <= $dt1 ) {

}

Do this :

if(strtotime('12-11-01') <= strtotime('2008-05-02'))
{
     // do your task here
}

You can use this code:

$d1 = strtotime($date1);
$d2 = strtotime($date2);
if($d2 <= $d1){
    // $date2 is before $date1
}
