Question

我正在利用PHP将表单中的输入字符串化为JSON。它目前正在格式化它

{"name":"asfd","username":"awsf","email":"kean","age":"21","gender":"Male","submit":"Submit"},  
{"name":"asdf","username":"asfd","email":"asdf@asdf","age":"21","gender":"Male","submit":"Submit"},

但它应该看起来更像这样，对吧？

[
{"name":"asfd","username":"awsf","email":"kean","age":"21","gender":"Male","submit":"Submit"},

{"name":"asdf","username":"asfd","email":"asdf@asdf","age":"21","gender":"Male","submit":"Submit"}
]

这是我目前的PHP。我该怎么做才能使它正确串化？

<?php
if (isset($_GET['name'])){
$json_data = json_encode($_GET);
// var_dump($json_data);
$file = file_put_contents('data.json', $json_data."," , FILE_APPEND | 
LOCK_EX);

?>
    <script type="text/javascript">
        ChangeName(<?php echo("'".$_GET['name']."'") ?>);

    </script>
    <?php } ?>

执行此操作的唯一方法是首先从文件中读取数据，对其进行解码，将新数组附加到该数据并再次将其编码为json并将其放入文件中，如下所示：

<?php
if (isset($_GET['name']))
{
    $data = json_decode(file_get_contents('data.json'), true);
    $data[] = $_GET;
    $json_data = json_encode($data);
    $file = file_put_contents('data.json', $json_data);
}

使用PHP对JSON进行字符串化，但语法错误
