php dynamically create date range for next 12 months with interval of 15 days

February 2, 2024

I want to create dropdown options dynamically with php as follows

01-March-2024 To 31-March-2024
15-March-2024 To 15-April-2024
01-April-2024 To 30-April-2024
15-April-2024 To 15-May-2024
01-May-2024 To 31-May-2024
15-May-2024 To 15-June-2024
01-June-2024 To 30-June-2024
15-June-2024 To 15-July-2024 ... And so on for next upcoming 12 months

What I tried is giving me as follows

01-March-2024 To 31-March-2024
01-April-2024 To 30-April-2024
01-May-2024 To 31-May-2024
01-June-2024 To 30-June-2024
01-July To 31 July 2024 ... And so on for next upcoming 12 months

PHP Code I am Using :

<select name="duration">
<?php
  for($i=0;$i<=12;$i++) {
    $time1 = strtotime("first day of +". $i." months");
    $time2 = strtotime("last day of +". $i." months");
?>
    <option value="<?php echo date("d-F-Y", $time1)?> To <?php echo date("d-F-Y", $time2)?>"><?php echo date("d-F-Y", $time1)?> To <?php echo date("d-F-Y", $time2)?></option>
 <?php } ?>
 </select>

>Solution :

I was a little wrong in that strtotime apparently doesn’t like fifteenth of $i months, but you can override the day in the date command:

<select name="duration">
    <?php
    for($i=0;$i<=12;$i++) {
        $time1 = strtotime("first day of +". $i." months");
        $time2 = strtotime("last day of +". $i." months");
        ?>
        <option value="<?php echo date("d-F-Y", $time1)?> To <?php echo date("15-F-Y", $time1)?>"><?php echo date("d-F-Y", $time1)?> To <?php echo date("15-F-Y", $time1)?></option>
        <option value="<?php echo date("15-F-Y", $time1)?> To <?php echo date("d-F-Y", $time2)?>"><?php echo date("15-F-Y", $time1)?> To <?php echo date("d-F-Y", $time2)?></option>
    <?php } ?>
</select>
