Just like you would in the example above -- only with dates that are
compliant with your RDBMS, and using the earliest date first. The
formats you give -- 'MM-DD-YYYY' won't work in most RDBMS'; typically
you go from most general to most specific, e.g. 'YYYY-MM-DD'. So, using
the dates you gave:
SELECT * FROM `table` WHERE `age` BETWEEN '1955-03-05' AND '1969-01-01';
The date fields may be subject to the UNIX epoch; if so, neither of the
dates above will be valid (epoch started 1970-01-01). Check the manual
for your RDBMS to see if this is the case.
Now, based on the OP's original question, about finding all users
between an age range, one would need to determine the start date and end
date prior to passing in the SQL. This can easily be done with
strtotime():
$ages = explode(',', $_GET['ages'], 2); // get the start/end ages
$startDate = date("Y-m-d", strtotime("-$ages[0] years"));
$endDate = date("Y-m-d", strtotime("-$ages[1] years"));
$sql = "SELECT * FROM `table` WHERE `age` BETWEEN $startDate AND $endDate";
Hope that helps.
