Answer 1

<?php 
    $dates = $day1 ;
    echo "<p>";
    for($i=0;$i<count($dates);$i++) {
        if(empty($dates[$i]))           ///
             continue;                  // 

        if($i>0 && ($i%3==0)) { echo "</p><p>"; }
        echo "<input type='checkbox' name='dates[]' value='".$dates[$i]."'/><label>".$dates[$i]."</label>";
    }
    echo "</p>";
?>

at the time of saving in to data base use

$dates = implode(',', $_POST['dates']);  // will save date in format of 1,2,3,4

at the time retrieving it again from database use

$dates = explode(',', $dateFromDB);   // this will give you array of dates
