Answer 1

你可以使用json_encode函數轉換成json。

<?php 
$db = new PDO('mysql:host=localhost;dbname=Contact', 'root', ''); 
$stmt = $db->query('SELECT * FROM myfeilds'); 
$results = $stmt->fetchAll(PDO::FETCH_ASSOC); /* it will give you array of result */ 

$jsonResult = json_encode($results) ; /* it will convert into json format */ 

echo $jsonResult ; /* this will show in ajax success calling */ 
?>
