I need to get the PHP foreach , the question id , and the answer of each question answered.

I can only get the id of the question, how would I also get the answer typed?

My foreach

<?
 if (isset($_POST['resposta'])) {


 foreach ($_POST['id_pergunta'] as $value) {

     echo $value."<br><br>";


 }



 }
?>

I have the form like this:

<form role="form" action="" method="post">





                          <div class="row setup-content" id="step-1" style="display: block;">
        <div class="col-xs-12">
            <div class="col-md-12">
                <h3 style="color: #0093cf;text-transform: uppercase;">teste1</h3>
                <div class="form-group">

                </div>
                <div class="form-group">
                    <label class="control-label">Resposta</label>
                    <input maxlength="100" type="text" id="resposta[]" name="resposta[]" required="required" class="form-control" placeholder="Resposta da pergunta">

How to deal with 2 arrays can be done as follows:

foreach(array_combine($_POST['id_pergunta'], $_POST['resposta']) as $p => $r)
{

   echo $p." ".$r.PHP_EOL;

}

array_combine - Create an array using an array for keys and another array for values
