<html lang="en">
        <head>
                <meta charset="UTF-8" name="viewport" content="width=device-width, initial-scale=1" />
                <link rel="stylesheet" type="text/css" href="css/bootstrap.css" />
        </head>
<body>
        <nav class="navbar navbar-default">
                <div class="container-fluid">
                        <a class="navbar-brand" href="https://sourcecodester.com">Sourcecodester</a>
                </div>
        </nav>
        <div class="col-md-3"></div>
        <div class="col-md-6 well">
                <h3 class="text-primary">Get Days Left In A Month Using PHP</h3>
                <hr style="border-top:1px dotted #ccc;"/>
                <div class="col-md-6">
                        <form method="POST" action="">
                                <div class="form-group">
                                        <label>Please enter a date</label>
                                        <input type="date" name="date" class="form-control"/>
                                </div>
                                <center><button class="btn btn-primary" name="get">Get Days</button></center>
                        </form>
                        <?php include 'get_days.php'?>
                </div>
        </div>
</body> 
</html>

Creating the Main Function

This code contains the main function of the application. This code will display the remaining days of a month. To make this just copy and write these block of codes below inside the text editor, then save it as get_days.php

<?php
        date_default_timezone_set("Etc/GMT-8");
        if(ISSET($_POST['get'])){
                $month=date("m", strtotime($_POST['date']));
                $day=date("d", strtotime($_POST['date']));
                $year=date("Y", strtotime($_POST['date']));
                
                $date=$year."-".$month."-".$day;
                
                $timestamp = strtotime($date);
        
                $daysleft = (int)date('t', $timestamp) - (int)date('j', $timestamp);
        
                echo "<center><h3><span class='text-danger'>".$daysleft."</span> days remaining</h3></center>";
