How to get past date from today

Here is the code,

$today = strtotime(date('y-m-d'));

for($i=0; $i < 7;$i++)

{

$days[] = date('y-m-d:l',($today-($i*24*60*60)));

}

print_r($days);die;

Output:

Array ( 

    [0] => 10-07-28:Wednesday    

    [1] => 10-07-27:Tuesday 

    [2] => 10-07-26:Monday  

    [3] => 10-07-25:Sunday  

    [4] => 10-07-24:Saturday   

   [5] => 10-07-23:Friday   

   [6] => 10-07-22:Thursday

 ) 

Note: The result might be different as your testing date will be different.
