解析错误：语法错误，我的代码中出现意外的'$ result'（T_VARIABLE）

Question

这段代码出了什么问题，我收到有关意外'$ result'的消息？我无法摆脱它。我搜索了很多关于这个问题，但没有找到解决方案。

<?php

//error_reporting(0);

if(isset($_REQUEST['v']) && !empty($_REQUEST['v'])){

    $conx = mysqli_connect("localhost", "root", "mypass", "country_db");

    if (!$conx) {
        echo "Error connecting database!";
        exit;
    }

    $search = $_REQUEST['v'];

    $query = "SELECT `country_name` FROM `apps_countries` WHERE `country_name` LIKE '$search%'";

    $result = mysqli_query($conx, $query); // here is the error

    if (mysqli_num_rows($result) > 0) {

        while ($d = mysqli_fetch_assoc($result)) {
            echo $d['country_name'];
        }

    }

    else{
        echo "Nothing matched with your query";
    }

}

else{
    echo "No data received from the server";
}

?>
