将 IF 语句添加到 PHP

Question

我有以下 PHP 文件，它运行良好，所有输出都显示出来，但是 IF 语句有问题。我不知道为什么它同时显示 IF 语句和两行星星的所有文本（字体真棒图标).为什么会这样，有人可以帮助我吗？谢谢

<?php
include('database_connection.php');
if(isset($_POST["action"]))
{
 $query = "
  SELECT * FROM items  WHERE product_status = '1'
 ";
 if(isset($_POST["brands"]))
 {   
   $brand_filter = implode("','", $_POST["brands"]);
  $query .= "  AND product BETWEEN '400' AND '600' ";
 }

        
 $statement = $connect->prepare($query);
 $statement->execute();
 $result = $statement->fetchAll();
 $total_row = $statement->rowCount();
 $output = '';
 if($total_row > 0)
 {
  foreach($result as $row)
  {
     
   $output .= '
            <div class="col-sm-4 col-lg-3 col-md-3">
                <div style="border:1px solid #ccc; border-radius:5px; padding:16px; margin-bottom:16px; height:450px;">
                    
                    <p align="center"><strong><a href="#">'. $row['hotel_name'] .'</a></strong></p>
                    <h4 style="text-align:center;" class="text-danger" >'. $row['product_price'] .'</h4>
                     
                     if($row["rating"]==1)
                                    {
                                         <span class="fa fa-star checked"></span>
                                        <span class="fa fa-star"></span>
                                        <span class="fa fa-star"></span>

                                    }
                                    if($row["rating"]==2)
                                    {
                                         <span class="fa fa-star checked"></span>
                                         <span class="fa fa-star checked"></span>
                                         <span class="fa fa-star"></span>

                                    }
                </div>

            </div>
            ';
        }
    }
    else
    {
        $output = '<h3>No Data Found</h3>';
    }
    echo $output;
}
