如何将循环结果添加到 $_POST[] 数组？

Question

Good day all, i am working on an Exam app, i created a foreach loop that will pull all the questions from the database and place it in an h4 tag

foreach($questions as $key => $question) {
        echo "<div class=\"form-group\">";
        //html output for the questions
        echo "<h4 class='questions'> $question</h4>"."<ol>";//display the questions

what i want to do here it to pass the result of the loop $questions to a $_POST[] array eg $question = $_POST['question'];

i tried doing this:

foreach($questions as $id => $question) {
        echo "<div class=\"form-group\">";
        //html output for the questions
        $uQuestions = $question;
        $uQuestions = $_POST['uQuestions'];
        echo "<h4 class='questions'> $question</h4>"."<ol>";//display the questions

i got an error

Notice: Undefined index: uQuestions in C:\xampp\htdocs\app\exam.php on line 86

how do i go about it?

thanks in advance

Seems like you get the assignment wrong. This:

$_POST['uQuestions'] = $question;

will put $question in $_POST but without a unique identifier. When the loop ends $_POST['uQuestions'] will contains the last $question from the loop.

A solution might be:

 $_POST['uQuestions' . $id] = $question;

than you will put all questions in $POST
