Question

i want make a table than can be input with existing data, and also the table already exist even before the data inputted,table created based on how many days in this month(i.e: right now is october so it have 31 tables since october have 31 days).
The question are i want to put date number in column date and days in column days, basically date =1 so days of week=saturday, date =2 so days of week=sunday(based on current calendar) and so on
i not quite sure about the logic, cause every time i tried, it only fill the first div or its fill the whole divcheck out my code below

<?php
$start = new DateTime('first day of this month');
$end = new DateTime('first day of this month + 1 month');
$period = new DatePeriod($start, new DateInterval('P1D'), $end);
for($i= 1; $i < date('t') + 1; $i++){
for($j =1;$j<=1;$j++){
echo "<td><a href='#modal-dialog' class='btn btn-xs btn-success' data-toggle='modal'><span class='fa fa-pencil'></span>i=".$i."</td>".PHP_EOL;
}

}
for($j =1;$j<11;$j++){
echo "<td></td>".PHP_EOL;;
}
echo "</tr>";
}
?>

You are doing it wrong. You loop through the days and build the columns. Your loop through the days should build the rows.
<tbody>
<?php
$day = date('Y-m-d',strtotime('first day of this month'));
for($i= 1; $i < date('t') + 1; $i++){
?>
<tr>
<td><a href='#modal-dialog' class='btn btn-xs btn-success' data-toggle='modal'><span class='fa fa-pencil'></span>i=<?php echo $i; ?></td>
<td><?php echo date('M-d',strtotime($day)); ?></td>
<td><?php echo date('l',strtotime($day)); ?></td>
<?php
for($j =1;$j<=8;$j++){
echo "<td></td>".PHP_EOL;
}
?>
</tr>
<?php
$day = date('Y-m-d', strtotime('+1 day', strtotime($date)));
} ?>
</tbody>
