    Like this (but it still won’t work):

    wp_send_json(
   array('post_title' => $post->post_title, 'person_name' => user_address(),)
);

    The above example correctly calls the function, but the function doesn’t work correctly in that context. The user_address() function echoes out content. In order to pass values into an array or to other functions, the called function must return values, not echo them. What you could do is have your base function return a value, then write a wrapper function that echoes whatever the base function returns. Then when you need content echoed, as with action hooks, you call the wrapper function. When you need values returned, as with array declarations, call the base function. Example:

    function get_the_value() {
   return 'foo';
}
function the_value() {
   echo get_the_value();
}
add_action('show_values', 'the_value');
$json = wp_json_encode( array('value'=> get_the_value(),));
