How to create in php a full year table HTML

Question

I need to create a table like this one in the image, for every year I choose (dynamically generated) :

It must be in PHP because the highlighting of the days comes from the database, it's better to stay on the server-side.

So the best way is to build the custom calendar by hand? Are there some native PHP functions to help build this more quickly?

Thanks for your time.

What about something like [this](https://stackoverflow.com/questions/3207749/i-have-2-dates-in-php-how-can-i-run-a-foreach-loop-to-go-through-all-of-those-d)? — PtrTon, Mar 14 '21 at 13:26

It seems like you could do something like...

PHP

$year = 2021;

$headings = ["Su", "Mo","Tu","We","Th","Fr", "Sa"];

echo "<table class=calendar>";           // Create the table
echo "<tr><td><b>Months</b></td>";       // Column heading for months
for ($x = 1; $x <= 37; $x++) {           // Column headings for days
    $title = ($headings[($x % 7) ]);
    echo "<td class=day>{$title}</td>";
}
echo "</tr>";

// Cycle through each month of the year
for ($month = 1; $month <= 12; $month++) {
    $thisMonth   = new DateTime("{$year}-{$month}");   // Create date object (defaults to 1st of month)
    $daysInMonth = $thisMonth->format("t");            // Get the number of days in the month
    $monthName   = $thisMonth->format("F");            // Get the month in textual form
    echo "<tr class=month><td class=monthName>{$monthName}</td>";
    $dayOffsetArray = [
        "Monday"    => 0,
        "Tuesday"   => 1,
        "Wednesday" => 2,
        "Thursday"  => 3,
        "Friday"    => 4,
        "Saturday"  => 5,
        "Sunday"    => 6,
    ];


    // Get the number of days to pad the month row with and output blank cells in a loop
    $offset = $dayOffsetArray[$thisMonth->format("l")];
    for ($i = 0; $i < $offset; $i++){
        echo "<td class=day></td>";
    }

    // Output the individual days
    for ($day = 1; $day <= 37  - $offset; $day++) {
        $dayNumber      = ($day <= $daysInMonth) ? $day : "";

        // Logic here is random to simulate data from the DB
        // you would need to alter to do checks against the DB etc.
        $highlightClass = (
            !(random_int(1, 100) % 15) && $dayNumber
                ? "highlightYellow"
                : (
                    !(random_int(1, 100) % 35) && $dayNumber ? "highlightGreen" : ""
                )
            );
        echo "<td class='day {$highlightClass}'>{$dayNumber}</td>";
    }
    echo "</tr>";
}
echo "</table>";

CSS

    table {
        border-collapse: collapse;
    }
    td {
        border: 1px solid #111;
        padding: 5px;
        text-align: center;
    }
    tr {
    }
    .monthName {
        width: 15ch;
    }
    .day {
        width: 2.5ch;
    }
    
    .day:nth-child(7n), .day:nth-child(7n+1)  {
        background: #aaa;
    }

    .day.highlightYellow {
        background: #ff6;
    }
    .day.highlightGreen {
        background: #2f7;
    }
