我目前正在尝试调试json_encode无法对我的LDAP服务器中的大型多层数组进行编码的情况。好吧，它可能并不大，但是它包含数字索引和非数字索引，部分深度约为3个级别，并且总体上可能包含约300个元素。
但是，我无法按照手册中的描述使json_last_error（）正常工作： https://www.php.net/manual/de/function.json-last-error.php
我没有在那里列出任何错误代码，而只是隐晦的响应“ 5”。 我已经发现了另一个stackoverflow问题，有人在处理响应“ 4”，这是json_decode抛出错误的情况： PHP json_decode return error code 4
但是，我无法在Internet上找到任何将这些数字响应解析为任何其他有意义的错误代码或消息的来源，因此我无法解密我的代码xD
有人可以帮我吗？^^
编辑： 因此，我发现由于有了nigelRen和aynber，我们有了JSON_SYNTAX_ERROR。
我检查了一个在线编码器，以了解发生了什么。奇怪的事情： 数组可以被编码！ 然后，我将JSON字符串输入到JSONLint中以对其进行验证，然后它起作用了！ 我什至将其输入到在线解码器中，而且可以正常工作！
那么为什么它在我的程序中不起作用？ 我在最新的XAMPP环境中使用了lumen（laravel 6.2）和最新的php（7.3.1ish）。
EDIT2： 这是匿名数据：
