SQL query in PHP script keeps "losing" one row - php

Question

Let's assume I have a table like this:
+------+---------+--------------+-------------+---------------+
| id | tstamp | product_id | name | configuration |
+------+---------+--------------+-------------+---------------+
| 3 | 15 | 02 | bike | abc |
| 2 | 16 | 03 | car | dfg |
| 1 | 11 | 04 | tree | ehg |
+------+---------+--------------+-------------+---------------+
When I run a simple query like
SELECT id, tstamp, product_id, name, configuration
FROM tl_iso_product_collection_item
ORDER BY `id` DESC
It returns 3 rows. As expected. Works, right? BUT, if I implement this query into a PHP script and try to fetch rows, theres always ONE missing. Always. Even in the most simple query. Where did I make a mistake?
Script looks like this:
<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);
$connection = mysqli_connect('localhost', 'user', 'pw', 'db');
mysqli_set_charset($connection,"utf8");
$query = "SELECT id, tstamp, product_id, name, configuration
FROM table
ORDER BY `id` DESC "
$result = mysqli_query($connection, $query);
while ($row=mysqli_fetch_row($result)) {
echo $row[0];
echo $row[1];
echo $row[2];
echo $row[3];
echo $row[4];
}
mysqli_close($connection);
?>
This will result in displaying only 2 out of 3 rows. My question is, why tho? If I insert the query above directly into phpmyadmin it shows 3 results, not 2. What is wrong here? Am I missing something? Thanks in advance.

$fetch_allgemein = mysqli_fetch_array($result_allgemein);
$fetch_configuration = mysqli_fetch_array($result_configuration);
You are fetching the first record for each query result here already – so the internal “pointer” to the current record gets advanced to the second record in each result set, and therefor when you loop over the result using
while ($row=mysqli_fetch_row($result_allgemein)) {
later on, the first record is of course omitted.
You will need to reset the “pointer” using mysqli_result::data_seek if you want to get all records in your loops after you’ve already fetched the first record each.
