                  <input type="text" placeholder="Name" class="form-control" ng-model="item.name" required>
                </div>
                <div class="col-md-5">
                  <input type="text" placeholder="Price" class="form-control" ng-model="item.price" required>
                </div>
                <button class="btn btn-danger btn-sm" ng-show="$last" ng-click="deleteField()"><span class="glyphicon glyphicon-remove"></span></button>
              </div>
            </div>
          </div>
        </fieldset>
        <button type="button" class="btn btn-success" ng-click="addFields()"><span class="glyphicon glyphicon-plus"></span> Add</button>
        <button type="button" class="btn btn-success" ng-disabled="liveForm.$invalid" ng-click="liveFormSubmit()"><span class="glyphicon glyphicon-floppy-disk"></span> Save</button>
      </form>

      <!-- Table data display -->
      <table class="table table-bordered live24u" style="margin-top:11px;">
        <thead>
            <tr>
                <th>Name</th>
                <th>Price</th>
            </tr>
        </thead>
        <tbody>
          <tr ng-repeat="stud in items">
            <td>{{ stud.name }}</td>
            <td>{{ stud.price }}</td>
          </tr>
        </tbody>
      </table>

    </div>
  </div>
</div>

</body>
<script src="main.js"></script>
</html>

Create main.js File:

Here we will write code for angular js and manage add more input fields. here write code for call api and get all data from tables. so let's create bellow file:

main.js

var liveApp = angular.module('liveApp', []);

liveApp.controller('studentData', function($scope, $http){
	$scope.success = false;
    $scope.error = false;

    $scope.retrive = function(){
    	$http.get("get_data.php").success(function(data){ 
	        $scope.items = data; 
	    });
    }

    $scope.itemList = [{id: 'firstField'}];

    $scope.addFields = function(){
        var addnewStudent = $scope.itemList.length+1;
        $scope.itemList.push({'id':'field'+addnewStudent});
    }

    $scope.liveFormSubmit = function(){
        $http.post('add_data.php', $scope.itemList)
        .success(function(data){
            if(data.error){
                $scope.error = true;
                $scope.success = false;
                $scope.msgError = data.comments;
            }
            else{
                $scope.error = false;
                $scope.success = true;
                $scope.messageSuccess = data.comments;
                $scope.retrive();
                $scope.itemList = [{id: 'firstField'}];
            }
        });
    }

    $scope.deleteField = function() {
        var itemLast = $scope.itemList.length-1;
        $scope.itemList.splice(itemLast);
    };

    $scope.msgCls = function(){
    	$scope.success = false;
    	$scope.error = false;
    }
});

Create get_data.php File:

in this file we will write code for getting data from php mysql database. so let's create get_data.php on your root directory.

get_data.php

<?php
	$db_con = new mysqli('localhost', 'root', 'root', 'laravel_test');

	$lstoutput = array();
	$msqsql = "SELECT * FROM items";
	$sqlquery=$db_con->query($msqsql);

	while($row=$sqlquery->fetch_array()){
		$lstoutput[] = $row;
	}

	echo json_encode($lstoutput);
?>

Create add_data.php File:

in this file we will write code for save data from php mysql database. so let's create add_data.php on your root directory.

add_data.php

    $alldata = json_decode(file_get_contents("php://input"));

    $count = count($alldata); 
    $output_res = array('error' => false);

    foreach($alldata as $key => $value){
        $studfname = $value->name;
        $studlname = $value->price;

        $msqsql = "INSERT INTO items (name, price) VALUES ('$studfname', '$studlname')";
        $mtquery = $db_con->query($msqsql);
    }

    if($mtquery){
        $output_res['comments'] = "($count) Items added successfully";
    }else{
        $output_res['error'] = true;
        $output_res['comments'] = "Cannot add Items";
    }

    echo json_encode($output_res);
?>
