While loop stopping after one time - php

Question

Noob alert here. I'm just (trying to) teaching myself PHP because I need it on my internship job. Now I am creating a survey and I am trying to use while loops to show the questions and their respective answers onto my XAMPP. I am using this code:
<?php
mysqli_select_db($conn, "surveyordina");
//code hier schrijven
$sql = "SELECT questions_body FROM survey_questions where subthema_id = 1";
$sql2 = "SELECT answer_body FROM survey_answers where answer_id = 1 or answer_id = 2 or answer_id = 3";
$result = mysqli_query($conn, $sql);
$result2 = mysqli_query($conn, $sql2);
if(mysqli_num_rows($result2) > 0){
while($row = mysqli_fetch_assoc($result)) {
echo "<br>" ."Vraag: <br>" . $row["questions_body"]. "<br>";
while($row_answer = mysqli_fetch_assoc($result2)) {
echo $row_answer["answer_body"]. "<br>";
}
}
}
else{
echo "No results";
}
Now the returning part of this code looks like this:
Vraag:
Is the organization aware of where all the personal data is stored? Be it on-site or in the cloud, hosted by the company or by a third party?
Yes
No
I don't know
Vraag:
Is the organization able to locate and find personal data of a particular data subject?
Vraag:
Does the organization have technology in place to return all personal data on a given data subject, given a single search from personnel?
Vraag:

I am trying to get the Yes, No, and I don't know parts under each and every question but only seem to get it under one of the questions.
Is there a method to return the whole answer part under each question? If so, am I on the right path or am I doing something completely wrong?
Thanks in advance.

Answer 1

Once you hit the end of a result-set, mysqli_fetch_assoc() doesn't just keep cycling through. So you're hitting the end of the $result2 set within the first outer loop, and then that's it, there are no more results to fetch.
You should fetch all of the $result2 results outside of the $result loop, assign the results to a variable, and then loop through that array within the $result loop.
Something like:
if(mysqli_num_rows($result2) > 0){
$result2Set = mysqli_fetch_all($result2, MYSQLI_ASSOC);
while($row = mysqli_fetch_assoc($result)) {
echo "<br>" ."Vraag: <br>" . $row["questions_body"]. "<br>";
foreach($result2Set as $row_answer) {
echo $row_answer["answer_body"]. "<br>";
}
}
}
