Find the dates ( month start and end dates) between the given two dates using PHP

When you want to pull the dates between two dates, where the between dates are connecting dots. If you want to list the complete date ranges through months. For example, to find the dates between below dates

date1 = '2022-12-29';
date2 = '2023-02-20';

expected output would be 

Start Date	End Date
2022-12-29	2022-12-31
2023-01-01	2023-01-31
2023-02-01	2023-02-20

 

<?php

/*
 * Returns array of month's start & end dates between provided dates.
 *
 * @param string $start_date
 * @param string $end_date
 * 
 *
 * @return array
 */
 function getDates($start_date, $end_date){
    $start_date_obj = new DateTime($start_date);
    $end_date_obj = new DateTime($end_date);
    
    $diff = $end_date_obj->diff($start_date_obj);
    $months = (($diff->y) * 12) + ($diff->m);
    
    $dates[] = array('start_date' => $start_date, 'end_date' => date('Y-m-t', strtotime($start_date)), 'suffix' => date('Y-m', strtotime($start_date)));
    $new_start_date = strtotime(date('Y-m-01', strtotime($start_date)));
    for($i = 1; $i <= $months; $i++){ 
        $new_start_date = strtotime("+1 months", $new_start_date);
        $dates[] = array('start_date' => date('Y-m-01', $new_start_date), 'end_date' => date('Y-m-t', $new_start_date) , 'suffix' => date('Y-m', $new_start_date));
    }
    $dates[] = array('start_date' => date('Y-m-01', strtotime($end_date)), 'end_date' => $end_date, 'suffix' => date('Y-m', strtotime($end_date)));
    
    return $dates;
}

$start_date = '2022-12-29';
$end_date = '2023-02-20';
$dates = getDates($start_date, $end_date);
print_r($dates);
?>

Output:
