This is a simple snippet of code that will return an array of days between two dates.

get_days.php
get_days_example.php

Read on for a little more info…

<?php
function GetDays($sStartDate, $sEndDate){
// Firstly, format the provided dates.
// This function works best with YYYY-MM-DD
// but other date formats will work thanks
// to strtotime().
$sStartDate = gmdate("Y-m-d", strtotime($sStartDate));
$sEndDate = gmdate("Y-m-d", strtotime($sEndDate));
// Start the variable off with the start date
$aDays[] = $sStartDate;
// Set a ‘temp’ variable, sCurrentDate, with
// the start date - before beginning the loop
$sCurrentDate = $sStartDate;
// While the current date is less than the end date
while($sCurrentDate < $sEndDate){
// Add a day to the current date
$sCurrentDate = gmdate(”Y-m-d”, strtotime(”+1 day”, strtotime($sCurrentDate)));
// Add this new day to the aDays array
$aDays[] = $sCurrentDate;
}
// Once the loop has finished, return the
// array of days.
return $aDays;
}
?>

Usage:

<?php
$aDays = GetDays('5th Feb 2007', '10th Feb 2007');
?>

You can use most date formats, such as:

GetDays('2007-01-01', '2007-01-31');

or

GetDays('19-02-2007', '25-02-2007');

Whatever strtotime can handle, you can pass to this function.

Hope it helps!
