Try this:

<?php
$from_date_time = strtotime($_POST['from_date']);
$to_date_time = strtotime($_POST['to_date']);

while ($from_date_time < $to_date_time) {
    echo date('Y-m-d H:i:s', $from_date_time);
    $from_date_time += 3600;
}

hello in MS SQL server 2005 you can do this by the following code of using CTE..

declare @dateh table(ind int identity(1,1),date1 smalldatetime,date2 smalldatetime)

insert into @dateh select '1/1/2011','1/2/2011'

select * from @dateh

;with T as
(
    select date1,date2 from @dateh as d
    union all
    select dateadd(hh,1,date1),date2 From T 
    where  dateadd(hh,1,date1)<= date2
)
Select date1 from T
