How to generate {0} json string by PHP?

Question

There is a json string and it's

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

I don't how to generate the '{}' by json_encode($data, JSON_UNESCAPED_SLASHES); I try several sample codes like:

$data = ["email", null, "text", "[email protected]"];  // the output is ["email",null,"text","[email protected]"]
$data = ["email", "", "text", "[email protected]"]; // the output is ["email","","text","[email protected]"]
$data = ["email", [], "text", "[email protected]"]; // the output is ["email",[],"text","[email protected]"]

Does anyone know how to do? Thank you. Regards.

echo json_encode($data);

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