• I have an array of timestamps referring to the days when a holiday home is booked.
• each timestamp is a round day.
• I want to turn this into an array of 'begins' and 'ends' pairs for consecutive dates

Are there any php functions I should be aware of for writing this function?

Or does anyone have any pointers for this kind of thing?

thanks!

edit:

example array:

Array
(
    [0] => 1273536000
    [1] => 1273622400
    [2] => 1273708800
    [3] => 1273795200
    [4] => 1273881600
    [5] => 1273968000
    [6] => 1274054400
    [7] => 1274140800
    [8] => 1274227200
)

where a day = 86400 (seconds)
