Issue in displaying selecting data - php

Question

My issue is to display the data. It repeats the same id in it several times.
<?php
$check_shared_section = mysqli_query($MYSQLi,"select * from `vp_wall_post` where `type` = 'section' and `username` = '".mysqli_real_escape_string($MYSQLi,$poster_username)."' ");
$get_section = mysqli_fetch_array($check_shared_section);
$section_post = trim(strip_tags($get_section["post"]));
$section_page = trim(strip_tags($get_section["page_id"]));
$section_id = trim(strip_tags($get_section["pid"]));
echo $section_id;
?>
These are the issues that I am facing. Please help me to solve this problem.
It shows the output id
e4zDFOL3jBgcH8YRfkzJ
e4zDFOL3jBgcH8YRfkzJ
e4zDFOL3jBgcH8YRfkzJ
I want to show different id

I'm not sure why you are seeing the same pid value multiple times as you don't have any looping in your code at all. However the reason you are not getting all the different pid values is that you're not looping the results of the query. You need to use a while loop on the result of mysqli_fetch_array e.g.
while ($get_section = mysqli_fetch_array($check_shared_section)) {
$section_post = trim(strip_tags($get_section["post"]));
$section_page = trim(strip_tags($get_section["page_id"]));
$section_id = trim(strip_tags($get_section["pid"]));
echo $section_id;
// do other stuff with the values
}
Note that if you want to further process the results outside the while loop, you will need to save the values into arrays e.g.
$section_posts = array();
$section_pages = array();
$section_ids = array();
while ($get_section = mysqli_fetch_array($check_shared_section)) {
$section_posts[] = $section_post = trim(strip_tags($get_section["post"]));
$section_pages[] = $section_page = trim(strip_tags($get_section["page_id"]));
$section_ids[] = $section_id = trim(strip_tags($get_section["pid"]));
echo $section_id;
// do other stuff with the values
}
// you can use other loops to further process the values here
// e.g. foreach ($section_posts as $index => $section_post) {
// you can use $index to access the corresponding values from
// the $section_pages and $section_ids arrays e.g.
// $section_page = $section_pages[$index]
