Php 用户输入未存储在数据库中

php mysql

Php 用户输入未存储在数据库中,php,mysql,Php,Mysql,我是php的初学者，我刚刚用php做了一个base64编码器和解码器。它工作正常，但我希望用户尝试使用的所有哈希都存储在数据库中。它没有显示任何语法错误，我也找不到任何奇怪的东西。请帮帮我。所有内容都在一个名为 index.php <?php $dbhost = 'localhost'; $dbuser = 'root'; $dbpass = ''; $db = 'base64'; $dbconn = mysql_connect($dbhost, $dbuser, $dbpass

结果
你忘了
mysql_query($query,$dbcon);

将其保留在$query变量之后
 用此代码替换您的代码
    <?php

$dbhost = 'localhost';
$dbuser = 'root';
$dbpass = '';
$db = 'base64';

$dbconn = new mysqli($dbhost,$dbuser,$dbpass,$db);

结果
SQL注入警报-阅读PDO上的准备语句使用mysqli\u*
函数，而不是mysql\u*
函数投票为输入错误；您从未执行过查询。@FunkFortyNiner感谢它现在可以工作，不客气。
