I have got Google calender recurring events like that:
a:1:{i:0;s:61:"RRULE:FREQ=WEEKLY;UNTIL=20130618T132500Z;BYDAY=MO,TU,WE,TH,FR";}
or
a:1:{i:0;s:49:"RRULE:FREQ=WEEKLY;UNTIL=20131123T210000Z;BYDAY=SA";}
I found the a lot of information on understading RRULE, but I don't know what does the strings in the beginning a:1:{1:0;s:61: mean. And I couldn't find information on that part.
Does anyone familiar with Google calendar tell me what does that mean?
