Topic awaiting preservation: PHP Class attribute values

Issue:

I have a user class that has the blueprint to create a new user and inserts its records into the database. One of the attributes is called dateInsterd that logs the creating date and time of creation.

If i set it with a hidden form input and make it the current time sting it works just fine.

but when i set it up in the class ass an attriubute it give e this error

error:
Parse error: syntax error, unexpected T_STRING, expecting ',' or ';'


The Code is this

1. This code works fine

class User {
	public $dtUpdated;
	public $access= 1;
	public $banned = 0;
}

code with error

class User {
	public $dtUpdated = strftime("%Y-%m-%d %H:%M:%S", time());
	public $access= 1;
	public $banned = 0;
}

can someone please tell me why i cant set the date inserted attribute to strftime("%Y-%m-%d %H:%M:%S", time()) in my object class

because you can only initialize this kind of attribute to constant values.

Everything else needs to go into a constructor.

I just want to thank you Tyberius Prime very much. It worked perfect i should have thought of that. I noticed you always answer my very quickly with really good advice and i want you to know i appreciate it.
