save sql datetime to php variables - php

Question

$date =$row2['DeliveryDate'];
$date now contains the date variable as a datetime, to display it I would use:
echo date_format($date, 'm-d-y');
the problem I'm having is extracting single values from $date for example:
$datetime = strtotime($row2['DeliveryDate']);
$mysqldate = date("d", $datetime);
returns this error:
Warning: strtotime() expects parameter 1 to be string, object given in
C:\xampp\htdocs\tutorials\DerBlatt\hebrewDateTrial.php on line 10
I've tried numerous ways to extract the day/month/year into single variables but nothing works
if someone can suggest a way it might work I'll be very greatfull;
I've copy/pasted code from many sites but all of them use an example of the date as a string, unfortunately i haven't found a solution for the datetime variable.
I wanna do something like:
$date =$row2['DeliveryDate'];
//whatever conversion code that comes in between.
$d = //the day from datetime
$m = //the month from datetime
$y = //the year from datetime

Answer 1

If you are using PHP 5.3 or better ,use the DateTime class .
if you want to display in this format $format='m-d-y';
Retrieving data from database .
$date =$row2['DeliveryDate'];
$date = DateTime::createFromFormat('Y-m-d H:i:s',$date);
if($date){ // if the date is correct
$yourdate = $date->format($format);
$year = $date->format('Y');
$month = $date->format('m');
$day = $date->format('d');
}
Saving to database .
$date = DateTime::createFromFormat($format,$date);
if($date){
$date = $date->format('Y-m-d H:i:s');
$row2['DeliveryDate'] = $date;
}else{
$row2['DeliveryDate'] = date('Y-m-d H:i:s');
}

Answer 2

Try this:
echo date('d',strtotime($row2['DeliveryDate']));
i think it will work.

Answer 3

so this is how i made it work (very funny)...
$m = date_format($row2['DeliveryDate'], 'm');
$d = date_format($row2['DeliveryDate'], 'd');
$y = date_format($row2['DeliveryDate'], 'y');
echo 'Month: '.$m.' Day: '.$d.' Year: '.$y;
Thank you guys for helping me, sometimes my best solution is just using my head...
