在PHP MySQL搜索中找不到结果时显示消息 [英] Displaying message when no results found in PHP MySQL search

问题描述

我有一个查询MySQL数据库的PHP搜索脚本。目前，当没有显示结果时，脚本显示并显示错误。如何在没有任何内容返回时显示没有找到结果的消息？

I have a PHP search script which queries a MySQL database. Currently, when no results are displayed the script shows and error. How can I make it display a message like "No Results were found" when nothing is returned?

我的PHP脚本是：

<?php

mysql_connect("localhost","username","password");
mysql_select_db("database");

if(!empty($_GET['q'])){
$query=mysql_real_escape_string(trim($_GET['q']));
$searchSQL="SELECT * FROM links WHERE `title` LIKE '%{$query}%'  LIMIT 8";
$searchResult=mysql_query($searchSQL);

while ($row=mysql_fetch_assoc($searchResult)){
    $results[]="<div class='webresult'><div class='title'><a href='{$row['url']}'>{$row['title']}</a></div><div class='desc'>{$row['description']}</div><div class='url'>{$row['url']}</div></div>";
}

echo implode($results);
}

?>

推荐答案

if (empty($results)) { 
    echo 'No results found'; 
} else {
    echo implode($results);
}
