使用PHP将数据附加到.JSON文件 [英] Append data to a .JSON file with PHP

问题描述

我有这个.json文件:

I have this .json file:

[
    {
        "id": 1,
        "title": "Ben\\'s First Blog Post",
        "content": "This is the content"
    },
    {
        "id": 2,
        "title": "Ben\\'s Second Blog Post",
        "content": "This is the content"
    }
]

这是我的PHP代码:

<?php
$data[] = $_POST['data'];

$fp = fopen('results.json', 'a');
fwrite($fp, json_encode($data));
fclose($fp);

问题是，我不确定如何实现它.每次提交表单时，我都会在上面调用此代码，因此我需要增加ID并使用[和{保留有效的JSON结构，这有可能吗?

The thing is, I'm not exactly sure how to achieve it. I'm going to call this code above every time a form is submitted, so I need the ID to increment and to also keep the valid JSON structure with [ and {, is this possible?

推荐答案

$data[] = $_POST['data'];

$inp = file_get_contents('results.json');
$tempArray = json_decode($inp);
array_push($tempArray, $data);
$jsonData = json_encode($tempArray);
file_put_contents('results.json', $jsonData);
