Expansion of the date type adding an age method
Returns the age in years between two dates. If no date param is provided it uses the server date as now.
It typically answers the question "How old are you|the dog|my car". The answer is derived by comparing the given "Date of birth" param (dob) with today. An optional "now" param can be used to answer the question "How old where xx at a given date".
Parameters
-dob
date, required
Sample Usage
// Calls the date type directly
date('2000-02-28') -> age
date('2000-02-28') -> age(date('2010-08-25'))
// Calls the age method that in turn calls the date type
age(date('2000-02-28'));
age(date('2000-02-28'),date('2010-08-26'))
age(-dob=date('2000-02-28'),-dod=date('2010-08-27'))
age(-dob=date('2000-02-28'),-dod=date('2010-08-28'))
age(-dob=date('2000-02-28'),-dod=date('2010-08-29'))
age(-dob=date('2000-02-28'),-dod=date('2010-08-30'))
age(-dob=date('2000-02-28'))
