Ack - cant wrap my head around this logic

I have 2 arrays. One is calendar days, one are events in that date range. I want to merge the two arrays into one array but only where the event date matches the calendar days. Any suggestions?


Here's the data:

CalArray

[7] => 050807
[8] => 050808
[9] => 050809
