Message:

I have a function that needs to return a simple json response.

        public function index(){



            $users = [

                [

                    "name" => "adam",

                    "age" => 20

                ]

            ];



            echo json_encode($users, JSON_PRETTY_PRINT);



        }

I have also have header for content type in my index.php file

    header("Content-Type: application/json");

But when I have a simple get request, the server also sends all the comments with <!-- --> with the json response. If I make a request so that the above index function gets invoked, the response will look something like this:

<!-- 

    It looks at the url and pulls out information to create a array and decides what to load

 -->



 <!-- 

    Super class for every other controllers

    Base controller

    Loads modals and views

-->



<!--

    PDO database class

    Model is going to use this class to interact with the database

 -->



[

    {

        "name": "samman",

        "age": 20

    }

]

How can I resolve this issue?

My Answer:
To fix the issue with PHP sending comments along with the JSON response, you can try the following solutions:

1. Remove the comments from your PHP files: Make sure to remove any unnecessary comments from your PHP files, especially those that are outside of PHP tags. Comments outside of PHP tags will be sent along with the JSON response.

2. Check for any whitespace or new lines before or after the PHP tags: Make sure there are no extra whitespace or new lines before or after the PHP tags in your PHP files. These can also be sent along with the JSON response.

3. Use output buffering: You can use output buffering to capture the output of your PHP script and then send only the JSON response without any additional content. Here's an example of how you can use output buffering:

php
ob_start();

// Your PHP code here

$users = [
[
"name" => "adam",
"age" => 20
]
];

echo json_encode($users, JSON_PRETTY_PRINT);

$output = ob_get_clean();
echo $output;


By using output buffering, you can capture the JSON response and send it without any additional content.

4. Check for any include or require statements: Make sure that any included or required files do not have any comments or output that could be sent along with the JSON response.

By following these steps, you should be able to resolve the issue with PHP sending comments along with the JSON response.
