How to change array indexing?

Question

PHP

I get data from the database using PDO PHP in this form:

but this form does not suit me, since the task is: to sort through all key = value pairs, without knowing the names of the keys,
I need to get the data like this:

[
    ["name" => "name", "value" => "Иван"],
    ["name" => "surname", "value" => "Ургант"],
]

How to do it with PDO or json_encode or whatever?
