将变量从ajax传输到PHP

I use Leaflet to show map, on onEachFeature function, I have inserted ajax to get variable to pass to PHP, like this

function onEachFeature(feature, layer) {
  layer.bindPopup(feature.properties.IDLo); 
  layer.on("click", function(e)
  {
    var popup = e.target.getPopup();
    var content = popup.getContent();
    $.ajax({
      url: "index.php",
      type: "GET",
      data: "content=" + content,
      success: function(data)
      {
        console.log(content);
      }
    });
  });   
};

And this is PHP code

<body>
        <h2>My Map</h2>
        <div>
            <?php 
            if(isset($_GET['content']))
                {
                    $uid = $_GET['content'];
                }
            else $uid = 0;
            ?>
        </div>
        <div><?php echo $uid;?></div>
        <div id="map"></div>
        <script src="js/new.js"> </script>
    </body>

I always get 0 result in PHP but on console in chrome, it's the content value. Is there any sugguest? Thanks in advance.

    Why not use the post method?

    JS:

    function onEachFeature(feature, layer) {
  layer.bindPopup(feature.properties.IDLo); 
  layer.on("click", function(e)
  {
    var popup = e.target.getPopup();
    var content = popup.getContent();
    $.post("index.php",{content},function(data) {
       console.log(data);
    });

  });   
};

    HTML/PHP:

    <body>
        <h2>My Map</h2>
        <div>
            <?php 
            if(isset($_POST['content']))
                {
                    $uid = $_POST['content'];
                }
            else $uid = 0;
            ?>
        </div>
        <div><?php echo $uid;?></div>
        <div id="map"></div>
        <script src="js/new.js"> </script>
    </body>

    DEMO PHP :

    <?php 
if(isset($_POST['content'])) {
   echo 'I came here via PHP, the value of content variable is: -> ';
   echo $_POST['content'];
}

?>
