GET multiple variable separated from POST form?

I am new to PHP, I am making a Quiz page. The answers in FORM are sent to test-submit.php as follow:

question1-answer1; question2-answer2; question3-answer2...

http://localhost/tracy/test-submit.php?q1=a1&q2=a1&q3=a2&q4=a1

So I am confused how to get all the data separately to import to SQL database?

• q1 = a1
• q2 = a2
• q3 = a1
• ...

What if I have 1000 questions in URL? Iam looking for any help. Really appreciated!!!

I tried with $_GET[''] but I don't know what to get. is it:

• $_GET['q1'];
• $_GET['q2'];
• $_GET['q3'];
• $_GET['q4'];
• $_GET['q5'];
• ...

You can loop through all the query params and check if the value corresponding to the key exists

foreach($_GET as $key => $val) {
    if(!empty($val)) {
        $save[$key] = $val;
    }
}

Then you can process the final $save array as you want.

More importantly, if you have 1000 questions, means large form value and doing database operations, you should use POST method instead of GET. In that case the loop will be similar:

foreach($_POST as $key => $val) {
    if(!empty($val)) {
        $save[$key] = $val;
    }
}
