Looping through Dates in PHP

Hi Experts,

How can I loop in between 2 dates?

For example, I have the following code:

//Loop through DR
        $date = new DateTime();
        $date_from = new DateTime($from); //'2015-08-01'
        $date_to = new DateTime($to); //'2015-08'14'
        $date_optput = '';
        $date_compare = '';
        
        for ($date = $date_from; $date <= $date_to; $date++):
            
            $date_optput = $date->format('D-M-y');
            echo $date_optput . '<br>';
        endfor;

Select allOpen in new window

However, this crashes my browser, ad I'm guessing because it goes through every millisecond? Which is what I don't want.

In comments I added my test data, so I am expecting the following output

1-Aug-15
2-Aug-15
3-Aug-15
4-Aug-15
...
14-Aug-15
15-Aug-15

Select allOpen in new window

Any help will be appreciated.
