Phpr_DateTime

The Phpr_DateTime class represents a date and time. Usually you don't need to create instances of this class manually. Some fields of LemonStand objects are instances of Phpr_DateTime class, for example the $order_datetime field of the Shop_Order class. The class has a method for returning a formatted date and time value as string.

Class methods

• format($format_string) – returns a value of the date and time represents by the object, as string. The $format_string parameter specifies a date/time format. The format string supports a number of specifiers, matching the specifiers of the PHP strftime function.

The date/time values are stored in the database in GMT time zone. To convert date/time values to a time zone specified in the configuration file and display this value, plese use the following code:

// Display the date and time when a product was added to the database
echo Phpr_Date::display($product->created_at, '%x %X');

The format string (the second parameter) matches the format string of the PHP strftime() function.

To calculate a difference between the current date and a date represented with a Phpr_DateTime object, use the following code: 

// Display the number of days between the current date and the 
// date when a product was added to the database
$interval = Phpr_DateTime::gmtNow()->substractDateTime($product->created_at);
echo $interval->getDays();
