I want to add a new line in order to group dates within a foreach loop.

Example:

2015-11-05

2015-11-07

2015-11-10
2015-11-1         


        

Answer 1

$temp="":
foreach($rows AS $row) {
        $my_date = $row['datetime_published'];
        echo $my_date.'
';
         if(strcmp($my_date,$temp)==0)
           echo '
';
        $temp = $my_date;

    }
