PHP JSON响应包括HTML布局

我在这里遇到问题:我正在尝试创建一个jQuery / AJAX / PHP实时搜索栏。我正在调用search.php,但每当我在控制台中输出响应时,我都会获得master.php文件的内容(这只是站点范围的布局)以及JSON编码的结果。我无法弄清楚导致这种情况发生的原因。

这是我的jQuery:

$(function() {
$("#search-text").keyup(function() {
    var $res = $(".search-results");

    $.ajax({
        type: "POST",
        url: "search.php",
        data: { query: $(this).val() },
        cache: false,
        success: function(html) {
            $res.show();
            $res.append(html);
            console.log(html);
        },
        error: function(xhr, status, error) {
            console.log("XHR: " + xhr);
            console.log("Status: " + status);
            console.log("Error: " + error);
        }
    });

    return false;

});
});

search.php

$key = $_POST["query"];
$db = new Database();
$db->query("SELECT * FROM users WHERE firstname LIKE :key OR lastname LIKE :key OR firstname AND lastname LIKE :key");
$db->bind(":key", '%' . $key . '%');
$rows = $db->resultset();

echo json_encode($rows);

谢谢!

在search.php中的echo之后写一个exit() 像这样:

$key = $_POST["query"];
$db = new Database();
$db->query("SELECT * FROM users WHERE firstname LIKE :key OR lastname LIKE :key OR firstname AND lastname LIKE :key");
$db->bind(":key", '%' . $key . '%');
$rows = $db->resultset();

echo json_encode($rows);

exit();

它应该阻止显示整个页面。

In search.php before sending $rows in json_encode() give one condition that will check $row is empty or not.like :
if(!empty($res))
    echo json_encode(array('status'=>'success','result'=>$rows));
else
    echo json_encode(array('status'=>'failed','result'=>[]));
In ajax check 
success: function(html)
{
    if(html.status=='success')
    {
            $res.show();
            $res.append(result.html);
            console.log(result.html);
     }
}
may be it will work..
