Header

    <!-- Add page icon -->
    <link rel="icon" href="assets/icon/sb.png" type="image/png" sizes="16x16" /> 
    <title>Birthday Reminder</title>

    <!-- Add external css  -->
    <link rel="stylesheet" href="assets/css/theme.css" />
</head>
<body>

Footer

</body>
</html>

Create Birthday Class

<?php

class Birthday {
    private $birthDays;
    public $today;
    public $notifications;


    public function __construct() {
        $this->today = new DateTime('today');
        // for demo purpose we set harry's birthday for every day
        $this->birthDays = [
            'Harry' => $this->today->format('d-m').'-1991',
            'Simon' => '17-11-1997',
            'Jenifier' => '17-11-1993',
            'Sinrela' => '15-08-1991'
        ];
        $this->notifications = [];
        
    }

    public function birthReminder() {
        foreach ($this->birthDays as $name => $birthDay) {
            $birthDate = new DateTime($birthDay);
            
            if($this->compareDay($birthDate) && $this->compareMonth($birthDate)) {
            
                array_push($this->notifications, [
                    "age" => $birthDate->diff($this->today)->y,
                    "name" => $name,
                    "dob" => $birthDay
                ]);
            } 
        }
    }

    protected function compareDay($birthDate) {
        return $birthDate->format('d') == $this->today->format('d');
    }

    protected function compareMonth($birthDate) {
        return $birthDate->format('m') == $this->today->format('m');
    }
}

Index file

It will connect the all dots like header, footer and age class file also.

We are using include once function instead of include read the difference here.

<?php
    include_once('birthdays.php');

    $person = new Birthday();
    $person->birthReminder();

    include_once('layout/header.php');
?>


<div class="container">
    <div class="page-header">
        <h1>Birthday Reminder <small>(<?= $person->today->format('d-M-Y'); ?>)</small></h1>
    </div>

    <div class="row">
        <div class="col-md-4 col-md-offset-4">
            <div class="panel panel-default theme-color mt-1">
                <div class="panel-heading theme-color text-center"> <span class="glyphicon glyphicon-gift"></span> What is today?</div>
                <div class="panel-body">
                    <?php if(count($person->notifications) > 0) { ?>
                        <?php foreach($person->notifications as $notification) { ?>
                            <div class="alert alert-success alert-dismissible text-center mt-1" role="alert">
                            <button type="button" class="close" data-dismiss="alert" aria-label="Close">
                                    <span aria-hidden="true">×</span>
                                </button>
                                <span class="glyphicon glyphicon-bell"></span>
                        
                                <?php 
                                    if(isset($notification['name'])){ 
                                        echo 'Wish <strong>'.$notification['name'].
                                        "</strong> a happy birthday! <br/> Whose date of birth is ".$notification['dob'].
                                        '<br/> This is '.$notification['name']."'s ".$notification['age']."th Birthday";
                                    } 
                                ?> 
                                
                            </div>
                        <?php } ?>
                    <?php } else { ?>
                        <div class="alert alert-danger text-center mt-1" role="alert">
                            <?= 'Today is '.$person->today->format('d-m-Y')." ! <br/> Nothing else"; ?>
                        </div>
                    <?php } ?>
                </div>
                <div class="panel-footer theme-color text-center">

Sum-up

This layout strategy will also help you to integrate the pre-built theme with PHP and its frameworks. So, understand carefully.

Obviously bootstrap helps us to minimize our custom CSS, that’s why we have used it.

That’s it.

Start your local server if you are working on local and test your code.

If you face any kind of issue or found any bug in the above code then please feel free to comment. I always eager to solve problems and learn new things.
