Need help using DateTime Object

[eldan88]

Hey Guys. I am fairly new to using the DateTIme Object and  trying to familiarize myself with it.  There is two things that I am really confused about

 

First, when I try to pass it a string in the constructor like "tomorrow" it throws me a "Catchable fatal error: Object of class DateTime could not be converted to string".  Below is the code I am using

$date = new DateTime('now');
echo $date;

The second thing I am confused is how use their constants such as

const string ATOM = "Y-m-d\TH:i:sP" ;

const string COOKIE = "l, d-M-y H:i:s T" ;

const string ISO8601 = "Y-m-d\TH:i:sO" ;

 

Are they predefined?

 

Any help would be really appreciated!

1.

echo $date;

That's where the problem was. You have to use something like $date->format(...) to get output.

 

2. Yes, they are predefined.
