php操作mysql数据库，返回结果展示在表格里

mysqli_connect()连接数据库
mysqli_select_db()选择库；

	$conn=mysqli_connect("localhost","php","");
	mysqli_select_db($conn,"php");
	//mysqli_query($conn,"set names utf8");
	//$sql="insert into php.php values(2,'jcy',88,15);";
    
	
	//$sql="insert into php.php values((2,'jcy',88,15)),(3,'dmy',77,15),(1,'wyd',97,16),(4,'zhx',75,15))";
	
	//mysqli_query($conn,$sql);
	$result = mysqli_query($conn,"select * from php");
	echo "";while($row=mysqli_fetch_array($result)){echo"";echo"";echo"";echo"";echo"";echo"";}echo"
