DTEND seems to be an invalid property

[imrealashu]

FREQ=MONTHLY;DTSTART=20181114T110000;DTEND=20191114T140000;INTERVAL=1 this seems to be invalid saying .
Error: Unknown RRULE property 'DTEND'
I checked the ical rules and seems to be present in the ruleset https://www.kanzaki.com/docs/ical/rrule.html

Even I'm using one PHP version which does letting me parse it properly https://github.com/simshaun/recurr

That's correct, it is a property that's present in the spec, but not supported by this library (currently). The reason is that this library does not support the concept of "duration" which is what DTEND represents, and it's not clear how to add support for duration without a major overhaul of the library. See discussion here: rlanvin/php-rrule#4

Note that the rrule properties as you have them are invalid. According to the spec, DTSTART and DTEND do not appear within the RRULE: property string, but at the top level as peers of the RRULE:. Supported properties (all of which this library supports):

       recur-rule-part = ( "FREQ" "=" freq )
                       / ( "UNTIL" "=" enddate )
                       / ( "COUNT" "=" 1*DIGIT )
                       / ( "INTERVAL" "=" 1*DIGIT )
                       / ( "BYSECOND" "=" byseclist )
                       / ( "BYMINUTE" "=" byminlist )
                       / ( "BYHOUR" "=" byhrlist )
                       / ( "BYDAY" "=" bywdaylist )
                       / ( "BYMONTHDAY" "=" bymodaylist )
                       / ( "BYYEARDAY" "=" byyrdaylist )
                       / ( "BYWEEKNO" "=" bywknolist )
                       / ( "BYMONTH" "=" bymolist )
                       / ( "BYSETPOS" "=" bysplist )
                       / ( "WKST" "=" weekday )
