How to properly convert an array to json?

Question

PHP

Hello. I have an array like:

Array
(
    [0] => [email protected]
    [1] => [email protected]
)

I need to convert it to json like this:

[
  {
    "email": "[email protected]",
  },
  {
    "email": "[email protected]",
  }
]

Please tell me how to do it. Regular json_encode() won't help here.
Thanks in advance to all who respond.

Answer 1

$data = array_map(function($email) {
  return ['email' => $email];
}, $data);
