生成PHP陣列對JS

Question

表使用方法：

-------------------- 
Product | Price 
-------------------- 
apples | 5 
oranges | 6 
peaches | 7 

如何從表中獲取行，並生成一個JSON陣列？

Answer 1

喜只需fetch從數據table並使用json_encode

$con = mysqli_connect('localhost','root','password','yourdatabase') or die("Could not connect database"); 
$result = mysqli_query($con,"select * from youtable"); 
$arr = array(); 
while($row = mysqli_fetch_assoc($result)){ 
$arr['myproducts'][] = $row;  
    } 
    $js_array = json_encode($arr); 
    echo $js_array; 
?> 

輸出

{"myproducts":[{"price":"4","products":"apples"},{"price":"5","products":"oranges"}]}

你應該簡單只是做SQL SELECT，然後它的結果應該是json_encode()

例子：

SELECT * FROM `table_name` 

Afther這在你的代碼：

while($r = $result->fetch_assoc()) { 
$newArr[] = $r; 
} 

echo json_encode($newArr);
