本题需要实现一个简易的基于网页的查询功能,包括连接数据库、数据库查询、处理用户输入、异常处理。用户的交互部分已经由Index.php提供,我们需要做的是完善它的逻辑。 本题难点在于调试部分,建议一边实现一边调试,并在关键地方打印变量值来进行调试。
下面给出数据库连接部分代码,默认数据库为本地mysql,用户名为root,密码为123456
<?php
...
$conn = mysql_connect("localhost", "root", "123456");
if (!$conn) {
// connection failed
echo "Could not connect to database: " . mysql_error();
}
// connection successful
...
mysql_close($conn)
?>
