How to set limit getstr by character?

Question

As I've been taught here, don't ever cut it off or mess with strings. decode the JSON and extract the relevant property

If you response is like that:

\"request_time":"2021-07-11 04:52:07\",\"elapsed_return_time_milliseconds\":26.65,\"access_ip\":null,\"error\":null,\"amount_sent\":1}

Means that you need decode with

$json = json_decode($string, true);

This is my updated code to get values, where $inicio contains the JSON response:

    $inicio = curl_exec($ch);
$json = json_decode($inicio, true);
$gettime = $json['header']['request_time'];

                echo json_encode(array("status" => 1, "msg" => "Error $number - Empty Response"));
            }else{
               echo json_encode(array("status" => 0, "msg" => "Ok $Number - $reqtime Response"));
            }

The output now is:

Ok 123456 - $2021-07-11 04:52:07 Response

So if I need get request_time value from this response:

 "header": {
    "api_version": "3.0.0",
    "type_connection": 1,
    "user": "",
    "request_time": "2021-07-11 05:46:24",
    "elapsed_return_time_milliseconds": 28.34,
    "access_ip": null,
    "error": null,
    "amount_sent": 1
  },

I can use this:

$gettime = $json['header']['request_time'];

Thank you very much! Please formulate the answer so I can mark as correctly

Don't cut it off or mess with strings. It looks like JSON so decode the JSON and extract the relevant property — ADyson, Jul 11 '21 at 08:10
Could you show me more with an short example? Please formulate an answer — Marcio, Jul 11 '21 at 08:13
Hang on, perhaps I misunderstood a little bit, are you saying it's a raw string before you json_encode it? It wasn't very clear what value you are starting off with? What is the original value of `$inicio`? — ADyson, Jul 11 '21 at 08:19
The value of `$inicio` is this json response `\"request_time":"2021-07-11 04:52:07\",\"elapsed_return_time_milliseconds\":26.65,\"access_ip\":null,\"error\":null,\"amount_sent\":1}` I need print only request_time and if `$reqtime` is empty send as json_encode with status 1, else if it's empty send as json_encode with status 0 — Marcio, Jul 11 '21 at 08:30
Inside `echo json_encode(array(` I need print the response previously stored in string `$reqtime` (it already occours but it print entire response and I need cutoff unecessary part, As you said I should decode JSON and extract but don't figure out how to do — Marcio, Jul 11 '21 at 08:39
Please add the full json object that you get to your question. The one you posted (My json response) seems to be truncated. — digijay, Jul 11 '21 at 08:42
`this json response`... But what you've shown us isn't valid JSON. Did you omit part of it? — ADyson, Jul 11 '21 at 08:47
Updated the question with full response, I shorten it because it was too big. About not being a JSON valid response maybe it was because this bars? \ \ If was it that you mean, I don't know why but the response appears like this with a lot \ \ \ when I print using the variable `$reqtime` Accessing the response by URL, I get the regular response (the same fully response that I've updated on question) Thank you all guys in advance It's really cool receive multiple supports like that — Marcio, Jul 11 '21 at 08:58
then you need to decode the JSON, extract the date value to a variable and then re-use it in your later output. Does this answer your question? [How do I extract data from JSON with PHP?](https://stackoverflow.com/questions/29308898/how-do-i-extract-data-from-json-with-php) — ADyson, Jul 11 '21 at 08:59
P.s. The backslashes ( \ ) were added by you when you tried to encode something to json which was contained double quotes to begin with. — ADyson, Jul 11 '21 at 09:01
@ADyson already tried a similar solution but it not worked when I try to print the response of $reqtime variable inside echo json_encode(array( Do you know if is possible decode the JSON and print the variable value inside an encode? — Marcio, Jul 11 '21 at 09:04
I will read this topic and try it again, probably I've missed something Really appreciate your help @ADyson Thank you! — Marcio, Jul 11 '21 at 09:06
Yes it's definitely possible to do what you described. Once you've decoded it it's just a PHP variable like any other. Maybe show us exactly what you tried already — ADyson, Jul 11 '21 at 09:09
I tried to get value of request_time from response like that: `$json = json_decode($inicio, true); $gettime = $json[0]['header']['request_time'];` the request_time value is inside header array, is this code correct ? If yes, I will update my question and you can formulate a answer since my problem must be solved decoding json but when I try print $gettime I get an empty value — Marcio, Jul 11 '21 at 09:14
`is this code correct `... No I don't think so because the original JSON is an object not an array so there won't be a [0] index. You can check the structure with var_dump — ADyson, Jul 11 '21 at 09:21
Oh my god, it worked!! I was trying with [0] that was the problem... I've updated my question, can you formalize the answer? so we done here after that, i believe i can do it alone i will try to learn more and more really thank you for your patience — Marcio, Jul 11 '21 at 09:48
Hello again @ADyson, I already finish all variables, is just pretty print and follow copying variables. Thanks to you. Just formulate a answer with `$json['header']['request_time'];` — Marcio, Jul 11 '21 at 12:22
