ID: 091122671325
Array ( [year] => 2009 [month] => 11 [day] => 22 )
2. If the year-month-day is the same as, or bigger than today, but smaller than 2000: year => 1909
ID: 091123671325
Array ( [year] => 1909 [month] => 11 [day] => 23 )

Caution: date_parse expects months 1..12 only.
date_parse("13/1/5769") for month=13, Ehul in Jewish calendar, results in month==3 instead of month==13.
It does, however, report the error array showing "Unexpected Character."
It would be nice if date_parse could handle the months properly (just report back a "13" for the month). The older approach of substr() is my workaround.

Careful - date_parse is perfectly happy with something like this:
date_parse("2006-2-31");
