如何使用PHP单击Time After按钮

Question

What I want to do is get the Time of the server, the moment I click a button. This time needs to be calculated(retrieved) at the time of click, this needs to be able to be done repeatedly if needed. Currently I have tried:
PHP Code

<?php
function getTime(){
    $Time = date('m/d/Y h:i:s a', time());
    return $Time;
}
?>

JS Code

function Funct(){
    var Time = "<?php echo json_encode(getTime()); ?>";
    console.log(Time);
}

HTML Code
<button onclick="Funct()">Get Time</button>
The problem is that when I click the button, after the first click, all of the other clicks Will not update, in fact the getTime function seems to be called when the page loads and leaves a string literal that is logged. How can I control when it calculates the Time? Thanks for the help!

Try this :

HTML

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>    
<button onclick="Funct()">Get Time</button>

JS

    function Funct(){
         var data = {};
         $.ajax({ type: 'POST', url: 'php_file.php', data: data, dataType: 'json', encode: true })
        .done(function (data) {
          console.log(data.time);
        }).fail(function (data) {
           console.log(data.responseText);
         });
    }

PHP

    <?php 
        $data['time'] = date('m/d/Y h:i:s a', time());
        echo json_encode($data);
