Question

I am looking to see if this is possible.

I am looking to post a an array of multiple values to a server using PHP as a middleware. I have a mobile app where the user will complete a questionnaire. I am wanting to post the question, answer and date for each question in one api call.

Is it possible to POST and deal with an array of values. Something like answers = [[question,answer,date],[question,answer,date],[question,answer,date],[question,answer,date]]

Any thoughts or best practices please do post below.

Update: if possible can you an example or link would be fab!

Answer 1

You can do this a couple of different ways. The first way would be to post an array and access it like so:

foreach($_POST['answers'] as $answer){

    $thisQuestion = $answer['question'];
    $thisAnswer =   $answer['answer'];
    $thisDate =     $answer['date'];

    // Do something with this current Question/Answer/Date combo
}

The second way would be to send a json string and to decode it in PHP:

$answers = json_decode($_POST['answer']);

The method you choose really comes down to which way it is easiest for you to send the data.
