PHP +Mysql question


OSNN Senior Addict
I am making a site that books cottage rentals. On my booking page i accept a check in and check out date i verify that they are valid dates, not in the past and that the Checkout date is greater then the check in. Im stuck now because i have to check my availability table to see if those days interfere with someone else's booking. I am having a hard time so i turn to you people of OSNN. Please. Is there a function that checks for overlapping in php or mysql. Or does anyone know some code to fix this problem. Thanks.
Something along the lines of

SELECT * FROM bookings WHERE cottage = '5' AND checkin BETWEEN :client_checkin AND :client_checkout AND checkout BETWEEN :client_checkin AND :client_checkout;

Replacing :client_checkin and :client_checkout with the checkin/checkout dates specified by the client. Try throwing that SQL at some test data and see if you get the response you are looking for.

That somewhat works but if the "stupid" client was to put a day in between the Arrival and Departure Date? i checked and that would fail the test. I'm surprised MYSQL doesn't just have function.
