这篇文章主要介绍了php简单实现查询数据库返回json数据,并附上2则示例代码,非常的简单实用,有需要的小伙伴可以参考下。

示例代码一:

// 设置返回json格式数据 header('content-type:application/json;charset=utf8'); //连接数据库 $link = mysql_connect("localhost", "root", "root") or die("Unable to connect to the MySQL!"); mysql_query("SET NAMES 'UTF8'"); mysql_select_db("jilinwula", $link) or die("Unable to connect to the MySQL!"); // 获取分页参数 $page = 0 ; $pageSize = 3; if(!is_null($_GET["page"])) { $page = $_GET["page"]; } if(!is_null($_GET["pageSize"])) { $pageSize = $_GET["pageSize"]; } // 查询数据到数组中 $result = mysql_query("select username,password from userinfo limit " . $page . ", ". $pageSize .""); $results = array(); while ($row = mysql_fetch_assoc($result)) { $results[] = $row; } // 将数组转成json格式 echo json_encode($results); // 关闭连接 mysql_free_result($result); mysql_close($link);

示例代码二:

'; $users[$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 ?>
