how to use angular controller variable in php variable in laravel blade file

Hi i am working on project in laravel 5.4 and in it in blade files angular is used and i am completely noob in angular

So here is a blade file in which i am adding a button to navigate to a different page with ID in href

<div ng-controller="MyOrderDetailsController as orderDialogCtrl">

<h1 ><em ng-bind="orderDialogCtrl.order.orderUID"></em> </h1>

     <?php
      $id = <<<EOD
     <h3><em ng-bind="orderDialogCtrl.order.orderUID"></em></h3>
             EOD;
      ?>

    <a class="btn btn-light btn-sm lw-btn" title="<?=  __tr('Return Product')  ?>" href=""><?=  __tr("Return Product")  ?></a>

Now my tag is printing the value but my problem is i want use that value in my php variable but when i use my variable it returns string not the value.Please help how i use that value in my php variable.
