如何使用 php 寫一個接口，然後將數據以 json 文件格式調用。
<?php
header('Content-Type:application/json; charset=utf-8');
header("Access-Control-Allow-Origin:*");
$servername = "localhost";
$username = "數據庫賬號";
$password = "數據庫密碼";
$dbname = "數據庫名稱";
// 創建連接
$conn = new mysqli($servername, $username, $password, $dbname);
// 檢測連接
if ($conn->connect_error) {
die("連接失敗: " . $conn->connect_error);
}
$sql = "select slug,title,created,text from typecho_contents";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
// 輸出數據
while($row = $result->fetch_assoc()) {
$data[]=$row;
}
$json = json_encode($data,JSON_UNESCAPED_UNICODE|JSON_PRETTY_PRINT);//把數據轉換為JSON數據.
exit($json) ;
} else {
echo "未查詢到結果！";
}
$conn->close();
?>
根據某個條件排序，將 32 行的 sql 語句改為下面的，意為根據 created 進行排序。
$sql = "select slug,title,created,text from typecho_contents order by created desc";
