Question

<?php header("content-type:text/html;charset=utf-8"); $mq=mysqli_connect('localhost','root',''); if(!$mq){ echo "链接失败"; } else{ echo "链接成功"; } if(mysql_query("CREATE DATABASE animal",$mq)){ echo "创建成功"; }else{ echo "创建失败"; }?>错因： Warning: mysql_query() expects parameter 2 to be resource, object given in D:\WAMPServer\wamp\www\phptext\phptext1\mysqltext.php on line10

Answer 1

第三行写错了$mq=mysqli_connect('localhost','root','');用mysqli扩展连接的数据库却用了mysql_query能不错吗？
