High score please instruct stdClassObject to convert array

For high scores, please kindly advise stdClassObject to convert the array and ask your eldest brother to give me some advice. if Google doesn't get the answer, I will post it to you. for high scores!
Problem:
The format of an array $ array obtained from json is as follows:

Array(    [0] => stdClass Object        (            [num_iid] => 6000026492        )     [1] => stdClass Object        (            [num] => 6000026308        )     [2] => stdClass Object        (            [num] => 6000025528        )     [3] => stdClass Object        (            [num] => 6000025650        )     [4] => stdClass Object        (            [num] => 6000027082

The array I want to get is
$ Array [0] = 6000026492
$ Array [1] = 6000026308
.................
How to Convert
Do not use for as much as possible, because there is a lot of data and frequent calls, there is no best way to convert.

Reply to discussion (solution)

After the conversion, I can use implode ("," $ array) to get the final result string: 6000026492,600 0026308 .....
Is there a one-step method for direct conversion?

Array(    [0] => stdClass Object        (            [num_iid] => 6000026492        )     [1] => stdClass Object.........

To 6000026492,600 0026308 .....

Nobody answered?
No one answered. another sleep night tonight

Provide an idea: you can send the json string. we recommend that you process the json string directly. For example, use a regular expression or str_replace.

Thank you.

// What you receive should be json data like this
$ S = '[{"num": 123 },{ "num": 456}]';
$ T = json_decode ($ s, 1); // The decoded struct is forcibly converted to an array.
// Then dimension the array
$ P = array_map ('stream', $ t );
// Connect to the string
Echo implode (',', $ p );

Is it difficult to decode the object directly as a JSON object...
