How to get the date/time of the email when it has been submitted through the the form?

Question

I'm learning how to code and I am setting a webpage with a form so a user can contact me directly into my email adress. At the moment this is what I receive in my email:

Firstname: test,
Name: test,
Email: test@gmail.com,
Phone: 0000000000,
Message: test 

I would like to get the date/ time it has been submitted and if possible a mention about the optin that has been consented:

Firstname: test,
Name: test,
Email: test@gmail.com,
Phone: 0000000000,
Message: test ,
date: xx/xx/xx,
time: xx:xx,
Consent: Acceptance of use of data

on my contact.php I have this

<?php

    $array = array("firstname" => "", "name" => "", "email" => "", "phone" => "", "message" => "", "firstnameError" => "", "nameError" => "", "emailError" => "", "phoneError" => "", "messageError" => "", "isSuccess" => false);
    $emailTo = "myemail@gmail.com";
    

   
    

    if ($_SERVER["REQUEST_METHOD"] == "POST") 
    { 
        $array["firstname"] = test_input($_POST["firstname"]);
        $array["name"] = test_input($_POST["name"]);
        $array["email"] = test_input($_POST["email"]);
        $array["phone"] = test_input($_POST["phone"]);
        $array["message"] = test_input($_POST["message"]);
        $array["isSuccess"] = true; 
        $emailText = "";
        
        if (empty($array["firstname"]))
        {
            $array["firstnameError"] = "Il manque votre prénom";
            $array["isSuccess"] = false; 
        } 
        else
        {
            $emailText .= "Firstname: {$array['firstname']}\n";
        }

        if (empty($array["name"]))
        {
            $array["nameError"] = "Il manque votre nom";
            $array["isSuccess"] = false; 
        } 
        else
        {
            $emailText .= "Name: {$array['name']}\n";
        }

        if(!isEmail($array["email"])) 
        {
            $array["emailError"] = "Ceci n'est pas un email";
            $array["isSuccess"] = false; 
        } 
        else
        {
            $emailText .= "Email: {$array['email']}\n";
        }

        if (!isPhone($array["phone"]))
        {
            $array["phoneError"] = "Que des chiffres et des espaces, svp...";
            $array["isSuccess"] = false; 
        }
        else
        {
            $emailText .= "Phone: {$array['phone']}\n";
        }

        if (empty($array["message"]))
        {
            $array["messageError"] = "Quel est votre message?";
            $array["isSuccess"] = false; 
        }
        else
        {
            $emailText .= "Message: {$array['message']}\n";
        }

       

        
       
        
        
        if($array["isSuccess"]) 
        {
            $headers = "From: {$array['firstname']} {$array['name']} <{$array['email']}>\r\nReply-To: {$array['email']}";
            mail($emailTo, "Un message de votre site", $emailText, $headers);
        }
        
        echo json_encode($array);
        
    }

    function isEmail($email) 
    {
        return filter_var($email, FILTER_VALIDATE_EMAIL);
    }
    function isPhone($phone) 
    {
        return preg_match("/^[0-9 ]*$/",$phone);
    }
    function test_input($data) 
    {
      $data = trim($data);
      $data = stripslashes($data);
      $data = htmlspecialchars($data);
      return $data;
    }
 
?>

on my js file , I have this

$(function() {

  $('#contact-form').submit(function(e) {
      e.preventDefault();

      var mention = document.getElementById('verif').checked;
      if (!mention )  {
        console.log(mention);
        $("#error").html("<p class='thank-you alert-danger'> Merci d'accepter les conditions</p>")
        return false;
      }else{
        $("#error").empty();
      }
     
      $('.comments').empty();
      
      var postdata = $('#contact-form').serialize()

      $.ajax({
          type:'POST',
          url:'php/contact.php',
          data: postdata,
          dataType: 'json',
          success: function(result) {

              if(result.isSuccess)
              {
                  $("#contact-form").append("<p class='thank-you'> Votre message a bien été envoyé. Merci de m'avoir contacté </p>")
                  $("#contact-form")[0].reset();
              }

              else

              {
                  $("#firstname + .comments").html(result.firstnameError);
                  $("#name + .comments").html(result.nameError);
                  $("#email + .comments").html(result.emailError);
                  $("#phone + .comments").html(result.phoneError);
                  $("#message + .comments").html(result.messageError);
              }

          }
        });
  });
})

This passes the "mention" to your PHP. But you don't need to pass it because if they can submit the form, that means they checked it.

var postdata = $('#contact-form').serialize() + '&mention=' + mention;

This appends "Datetime" and "Consent" to your end of your email message. Datetime is whatever you have server timezone set to. You can read more about date and timezones on the PHP documentation: https://www.php.net/manual/en/function.date.php

        if($array["isSuccess"]) 
        {
            $emailText .= "Datetime: " . date('Y-m-d H:i:s') . "\n";
            $emailText .= "Consent: Acceptance of use of data\n";
            $headers = "From: {$array['firstname']} {$array['name']} <{$array['email']}>\r\nReply-To: {$array['email']}";
            mail($emailTo, "Un message de votre site", $emailText, $headers);
        }
