How can I increase the json_encode depth limit

Question

How can I set the maximum depth limit to unlimited for json_encode function in PHP?

My problem is;

$array = 
[
    [
       [
          ['hello'],
       ],
    ],
];

Json_encode function returns false when I add more than 3 arrays multidimensionally. I wanna remove this limit. How can I do it?

Thanks.

Does [this code](http://sandbox.onlinephpfunctions.com/code/566f4af4ef99c08289f2d8b4118a56d103dca2ee) work for you on your own PHP installation? Because it works fine on a normal PHP installation — apokryfos, Jan 14 '21 at 21:12
I don't run into a depth limit. I increased it to 6 levels and it still works. — Barmar, Jan 14 '21 at 21:12
I can run this script my localhost. But I can't use on hosting. — Kaan Yılmaz, Jan 14 '21 at 21:13
`json_encode()` has a 3rd argument `$depth` that specifies the depth limit. It defaults to 512. — Barmar, Jan 14 '21 at 21:14
@Barmar "Malformed UTF-8 characters, possibly incorrectly encoded" — Kaan Yılmaz, Jan 14 '21 at 21:15
That has nothing to do with depth, it means there are invalid characters in the string. — Barmar, Jan 14 '21 at 21:16
Use the `JSON_INVALID_UTF8_IGNORE` or `JSON_INVALID_UTF8_SUBSTITUTE` flags. — Barmar, Jan 14 '21 at 21:17

The json_encode function accepts a depth parameter: https://www.php.net/manual/en/function.json-encode

<?php
$array = 
[
    [
       [
          ['hello'],
       ],
    ],
];

$text = json_encode($array, 8);
?>

Since the default is 512, this won't fix the problem. And the error message is not about the depth. – Barmar Jan 14 '21 at 21:16
@Barmar This answers the question being asked. I see the discussion in the comments, the question should be updated accordingly. – pyb Jan 14 '21 at 21:19
It would only answer the question being asked if his arrays were nested more than 512 levels. – Barmar Jan 14 '21 at 21:20
That is a good idea. That was not obvious to me however. OP said "I can run this script my localhost. But I can't use on hosting." so it could have been a limitation on the host behalf. – pyb Jan 14 '21 at 21:38
