计数斜线

Question

<?php  
    require_once 'DbConnect.php';

    $response = array();

    if(isset($_GET['apicall'])){

        switch($_GET['apicall']){

            case 'add_data':
                if(isTheseParametersAvailable(array('name','email', 'phone'))){
                    $name = $_POST['name']; 
                    $phone = $_POST['phone']; 
                    $email = $_POST['email'];

                    $stmt = $conn->prepare("INSERT INTO users(name, email, phone) VALUES (?, ?, ?)");
                    $stmt->bind_param("sss", $name, $email, $phone);

                    if($stmt->execute()){

    foreach($params as $param){
