Need help with calendar please! PHP

Question

Hello there! I want to learn how to create a working calendar so I find a tutorial on youtube & I created this code but it's not working properly. Can someone show where it's failing so I can get it to work?

Thanks!

´´´PHP <?php

date_default_timezone_set('Asia/Tokyo');

// Get prev & next month if (isset($_GET['ym'])){ $ym = $_GET['ym']; } else { $ym = date('Y-m'); }

$timestamp = strtotime($ym,"-01"); if($timestamp === false){ $timestamp = time(); }

// Today $today = date('Y-m-d', time());

// For H3 title $html_title = date('Y / m', $timestamp);

// Create prev & next month link $prev = date('Y-m', mktime(0, 0, 0, date('m', $timestamp)-1, 1, date('Y', $timestamp))); $next = date('Y-m', mktime(0, 0, 0, date('m', $timestamp)+1, 1, date('Y', $timestamp)));

// Number of days in the month $day_count = date('t', $timestamp);

// 0:Sun 1:Mon 2:Tue ... $str = date('w', mktime(0, 0, 0, date('m', $timestamp), 1, date('Y', $timestamp)));

// Create Calendar!! $weeks = array(); $week = '';

// Add empty cell $week .= str_repeat('<td></td>', $str);

for ( $day = 1; $day<=$day_count; $day++, $str++){

$date = $ym. '-'.$day;

if ($today==$date){
    $week .= '<td class="today">' .$day;
} else {
    $week .= 'td'.$day;
}
$week .= '</td>';

// End of the week OR End of the month
if ($str % 7==6 || $day == $day_count){

    if($day==$day_count){
        // Add empty cell
        $week .= str_repeat('<td></td>', 6 - ($str % 7));
    }

    $weeks[] = '<tr>' .$week. '</tr>';

    // Prepare for new week
    $week='';
}

}

?>

<style>
    .container{
        margin-top: 80px;
    }
    th {
        height: 30px;
        text-align: center;
    }
    tr {
        height: 100px;
    }

    .today {
        background-color: orange;
    }
    th:nth-of-type(7),td:nth-of-type(7){
        color: blue;
    }
    th:nth-of-type(1),td:nth-of-type(1){
        color: red;
    }

</style>

</head> <body> <div class="container"> <h3><a href="?ym=<?php echo $prev; ?>"><</a><?php echo $html_title; ?><a href="?ym=<?php echo $next; ?>">></a></h3> <br /> <table class="table table-bordered"> <tr> <th>S</th> <th>M</th> <th>T</th> <th>W</th> <th>T</th> <th>F</th> <th>S</th> </tr> <?php foreach ($weeks as $week){ echo $week; } ?> </table> </div> </body> </html>

I would suggest you review this tutorial [here[(https://www.startutorial.com/articles/view/how-to-build-a-web-calendar-in-php) This will help you set up a calendar by using Classes. First off, I will say that creating a calendar is extremely difficult to do, there are a lot of things you need to account for. That being said, checkout the link, and take a look.
