1.php程序
<?php mysql_connect("localhost","root",""); mysql_select_db("myhospitalv2"); $q=mysql_query("SELECT * FROM user2 "); while($e=mysql_fetch_object($q)) $output[]=$e; print(json_encode($output)); mysql_close(); ?> |
2.瀏覽器返回結果
| [{"id":"1","name":"Tony","sex":"1","birthyear":"1999"},{"id":"2","name":"Jim","sex":"1","birthyear":"1987"},{"id":"3","name":"Lucy","sex":"0","birthyear":"1988"},{"id":"4","name":"Tom","sex":"1","birthyear":"1980"}] |
3.總結
使用php引擎操作
MySQL數據庫，若返回結果為記錄集，將記錄集中記錄進行重新存儲，如上
$q=mysql_query("SELECT * FROM user2 "); while($e=mysql_fetch_object($q)) $output[]=$e; |
然后調用json_encode（）進行JSON數據封裝，可得到正確的JSON數據格式，用于不同設備間的數據傳輸。
