PHP how do you set the default date to a new one?

I tried to find how to set a date field to current date if the user does not fill it in but I am out of ideas can someone help me?? So for example if you user does not choose a date the date part should be today's date: 09/25/2020... Here's the basic html:

<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="utf-8">
        <meta name="viewport" content="width-device-width, intial-scale-1.0">
        <link rel="stylesheet" href="styles/main.css">
        <title>Find rest - add Infection</title>
    </head>
    <nav>
        <a href="index.html">Home</a>
    </nav>
        <body>
        <?php 
        //php invalid.
            if($_SERVER["REQUEST_METHOD"] == "POST"){
                $error_end = "";
                if(!$validEnd){
                    echo "Invalid end date: Please enter date after March 1 2020... \r\n";
                    $error_end = 'border: red 5px solid';
                }
            }
        ?>
<form>
        <table>
        <tr class="repeat_example">
                    <td>end_date <br><input type="date" name="end_date" id="end_date" value="<?php echoIfExists($_POST,"end_date","")?>" 
                    style="<?php echo $error_end; ?>"></td>
                    <td>date</td>
                    <td>The end_date of the infection if left empty
                        it should default to current date.</td>
                </tr>
        </table>
<br><br>
            
                <label> Write new Form!</label><input type="submit">
            </form>
        </body>
    </div>
</html>

And here's my PHP:

<?php

//constants
define("endDate", "end_date");

//Helper function
function valueIfExists($array, $key, $default){
    if(array_key_exists($key,$array)){
        return $array[$key];
    } else {
        return $default;
    }
}

if($_SERVER['REQUEST_METHOD'] == "POST"){

    $endTime = new dateTime(valueIfExists($_POST, endDate, "0"));
    $ref = new dateTime("03-01-2020");
    $current = new dateTime(strtotime(date("m-d-Y")));
    
    if($endTime->getTimeStamp() < $ref->getTimeStamp()){
        $isValid = false;
        $validEnd = false;
    }
    if($endTime->getTimeStamp() == "0"){
        $isDefault = true;
    }
}else {
    $isValid = false;
}



//Routing
if($isValid){    
    //process
    include "echo.php";
    exit(); //Emmit echo page if form is valid
} else {
    include "add_infection.php";
    exit(); //Emit the form if form is not valid
}

So if the user does not input in another date I want the form for the date part to display the current date...

thanks,

HTML5 date input defines the format as ISO8601.

You can set the default value of an input as

<input type="date" value="2020-09-25">

and this is obtained with the following PHP code:

date('Y-m-d');

so:

$date = isset($_POST['end_date']) ? $_POST['end_date'] : date('Y-m-d');
