在PHP MySQL搜索中找不到结果时显示消息
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);
}
?>
答
if (empty($results)) {
echo 'No results found';
} else {
echo implode($results);
}
