调用mysqli函数出现问题,已经配置好环境
$mysqli=new mysqli("localhost","root","12345","student");
$query="select * from person";
$result=$mysqli->query("$query");
if($result){
while($obj=$result->fetch_object()){
var_dump($obj);echo "
n";
}}else{
echo "查询失败";
}
$result->free();
$mysqli->close();
?>
------解决方案--------------------
把错误输出看看
if($result=$mysqli->query(......)) {//。。。。}else { echo $mysqli->error;//把错误输出看看}<div class="clear"></div>
