Introduction
To be honest am not sure what you mean by is it possible using function? but i guess you want a universal function but i think a simple class would also do the trick.
Observation
it should also only run the report for 24 Feb 2013 to 3 March 2013.
Please note that from Sunday 24 Feb 2013 to Sunday 3 March 2013 is 8 days and more than 1 weeks which may result to overlapping data if you are ploting graphic or using it for analytic. I would suggest you limit it to 1 weeks which is Sunday, 24 Feb 2013 to Saturday, 2 March 2013
Here is what i mean
// imagine today is Today is 4 March 2013
$today = DateTime::createFromFormat("d F Y", "4 March 2013");
$date = new PeroidDate();
vprintf("%s to %s", $date->getPeroid($today));
Output
Sunday, 24 February 2013 to Saturday, 02 March 2013
Other Examples
Example 1
// Example
$date = new PeroidDate();
print_r($date->getPeroid());
Output
stdClass Object
(
[start] => Sunday, 31 March 2013
[end] => Saturday, 06 April 2013
)
//or
Sunday, 31 March 2013
Example 2
Lets Imagine you want to get report for before valentine period that is "before February 14th"
print_r($date->getPeroid(new DateTime("2013-02-14")));
Output
stdClass Object
(
[start] => Sunday, 03 February 2013
[end] => Saturday, 09 February 2013
)
Example 3
Lets Imagine you want a range of date instead of a single range,eg. You want the date between January 1st and the Current Time(Probably you want to use it for a select box) then you use PeroidDate::getBetween
print_r($date->getBetween(new DateTime("2013-1-1"), new DateTime()));
Output

(
[0] => stdClass Object
(
[start] => Sunday, 06 January 2013
[end] => Saturday, 12 January 2013
