我試圖從我的LAMP服務器獲取產品數據。但我沒有得到迴應。問題似乎是array_push不能正常工作,因爲我可以在使用echo之前打印數據。php:無法爲數組賦值並將其作爲響應傳遞
我對PHP相當陌生。
感謝您的提前幫助。
<?php
ini_set('display_errors', 'On');
error_reporting(E_ALL);
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "DB";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
$sql = "SELECT * FROM Produkt";
$result = $conn->query($sql);
// check for empty result
if (mysqli_num_rows($result) > 0) {
// looping through all results
// products node
$response["products"] = array();
while ($row = mysqli_fetch_assoc($result)) {
// temp user array
$product = array();
$product["ID"] = $row["ID"];
$product["Name"] = $row["Name"];
// push single product into final response array
//print json_encode($product);
array_push($response["products"], $product);
}
// success
$response["success"] = 1;
// echoing JSON response
echo json_encode($response);
} else {
// no products found
$response["success"] = 0;
$response["message"] = "No products found";
// echo no users JSON
echo json_encode($response);
//print json_encode($response);
}
?>
如果你只需從數據庫中選擇'ID'和'Name'(改變你的sql),你就可以執行'$ response ['products'] [] = $ row;'在while循環中 – Rasclatt
