PHP错误地将JSON编码到文件

我正在解决这个问题。在preg_从PHP中分离后，我得到了和数组。我想要的是转换成JSON。我尝试了几乎所有的方法，但代码仍然写得很糟糕，似乎根本没有编码。这是我的部分代码

if(isset($_POST['SubmitButton'])){
    $content = $_POST['content'];
    $split = preg_split('/(\/>)/', $_POST['content']);
    $json = json_encode($split, true);
    file_put_contents("newfile.json", $json);
    $message = "<xmp>".$content."</xmp>";  
}

原始数组如下所示：

请你告诉我哪里出错了好吗？

有一个问题似乎是由于不接受

true

参数引起的。相反，它在该位置使用选项标志，在您的情况下，lexer将其解析为

1

，与

JSON\u HEX\u标记

选项标志相同。结果是

\u003C

而不是

您想要的结果/输出是什么？总之是正常的JSON。。没关系。。我认为UTF-8的编码语言不好，我不确定。。所需的结果可以是[0:{path….}..主要是它将包含JSON拥有的所有内容：）它有什么问题？看起来不错？用所需的输出更新您的问题，您的代码可能无法反映您所需的意图，请参阅我的答案。我想您可能希望将XML属性分解为JSON属性，但我想确定。
