//需要执行的SQL语句
//单条
$sql="select id,name from tbl_user where id=1";
//多条数据
//$sql="select id,name from tbl_user";

//调用conn.php文件进行数据库操作 
require('Conn.php'); 

//提示操作成功信息,注意:$result存在于conn.php文件中,被调用出来 
if($result) 
{ 

//	$array=mysql_fetch_array($result,MYSQL_ASSOC);
	
		
	/*数据集

	$users=array();
	$i=0;
	while($row=mysql_fetch_array($result,MYSQL_ASSOC)){

			echo $row['id'].'-----------'.$row['name'].'';
			$users[$i]=$row;
			$i++;

	}
		echo json_encode(array('dataList'=>$users));

	*/

	/*单条数据*/

	$row=mysql_fetch_row($result,MYSQL_ASSOC);
	
	echo json_encode(array('jsonObj'=>$row));
} 

mysql_free_result($result);
//释放结果
mysql_close();
//关闭连接

?>

运行结果------------------------------------
单条数据:{"jsonObj":{"id":"1","name":"lmw"}}

多条数据:{"dataList":[{"id":"1","name":"lmw"},{"id":"2","name":"xxj"},{"id":"3","name":"xxxj"}]}
