从PHP中的嵌套JSON获取数据

我创建了一个自定义API，它通过PHP获取JSON。现在我的问题是我想解码JSON 所以我可以从我的PHP文件中编辑它，但得到错误/空白屏幕，上面没有内容，只有ID，Name是est。但没有价值观

我使用了以下代码

    <?php
$string = file_get_contents("api/read.php");
//echo string;
$json_a = json_decode($string, true);
echo 'ID is: ' . $json_a['id'];
echo 'Name is: ' . $json_a['name'];
echo 'Email is: ' . $json_a['email'];
echo 'Age is: ' . $json_a['age'];
echo 'Destignation is: ' . $json_a['designation'];
echo 'Created on: ' . $json_a['created'];
?>

这回答了你的问题吗

file\u get\u contents（）

将获取文件内容，而不是PHP生成的内容。@I3est不，很抱歉没有。@Syscall那么如何获取PHP生成的内容呢？内容您需要从Web服务器获取它（例如：

http://your.serveur/read.php

）。但实际上，我看不出给定代码的目的是什么。您正在对数据进行编码，以便在“相同”的时间内对其进行解码。正确的？

<?php
    header("Access-Control-Allow-Origin: *");
    header("Content-Type: application/json; charset=UTF-8");
    
    include_once '../config/database.php';
    include_once '../class/employees.php';

    $database = new Database();
    $db = $database->getConnection();

    $items = new Employee($db);

    $stmt = $items->getEmployees();
    $itemCount = $stmt->rowCount();


    //echo json_encode($itemCount);

    if($itemCount > 0){
        
        $employeeArr = array();
        $employeeArr["body"] = array();
        $employeeArr["itemCount"] = $itemCount;

        while ($row = $stmt->fetch(PDO::FETCH_ASSOC)){
            extract($row);
            $e = array(
                "id" => $id,
                "name" => $name,
                "email" => $email,
                "age" => $age,
                "designation" => $designation,
                "created" => $created
            );

            array_push($employeeArr["body"], $e);
        }
        echo json_encode($employeeArr, JSON_PRETTY_PRINT);
    }

    else{
        http_response_code(404);
        echo json_encode(
            array("message" => "No record found.")
        );
    }
?>
