Question

我想编写php将信息添加到json id包中。我希望它在同一区域。对不起，我打的英文不好。我使用翻译。

我的代码：-

<?php
$donatename = $_POST['donatename'];
$donateURL = $_POST['donateurl'];
    $json1_str = '{
        "transaction": "'.$fti_u.'",
        "donatename": "'.$donatename.'",
        "donateURL": "'.$donateURL.'",
        "releaseddate": "'.$fttime_u.'"
    }';

$json1 = json_decode($json1_str, true);
$json2['packages'][] = $json1;
$jsonData = json_encode($json2, JSON_PRETTY_PRINT | JSON_UNESCAPED_SLASHES);

file_put_contents('data.json', $jsonData, FILE_APPEND);
?>

---我目前正在得到的输出---

{
    "packages": [
        {
            "transaction": "",
            "donatename": "",
            "donateURL": "",
            "releaseddate": ""
        }
    ]
}{
    "packages": [
        {
            "transaction": "",
            "donatename": "",
            "donateURL": "",
            "releaseddate": ""
        }
    ]
}

----预期-----

{
    "packages": [
        {
            "transaction": "",
            "donatename": "",
            "donateURL": "",
            "releaseddate": ""
        },
        {
            "transaction": "",
            "donatename": "",
            "donateURL": "",
            "releaseddate": ""
        }
,        {
            "transaction": "",
            "donatename": "",
            "donateURL": "",
            "releaseddate": ""
        }
    ]
}

错误：

第10行的解析错误：...“”}]} {“ packages”：[ -------------------- ^预期为'EOF'，'}'，'，'，']'

您想将数据添加到现有内容中，因此只需读取现有数据文件，添加新内容，然后使用新版本的数据覆盖现有文件...

$json1 = json_decode($json1_str, true);
// Load existing content
$json2 = json_decode(file_get_contents('data.json'), true);
$json2['packages'][] = $json1;
$jsonData = json_encode($json2, JSON_PRETTY_PRINT | JSON_UNESCAPED_SLASHES);

file_put_contents('data.json', $jsonData);  // Remove the append
