How do I print a selected list item from my MySQL database using php?

Question

Let's say I have a menu with a category called animals. I access the MySQL database like so for the animals.

include_once 'config.inc';
$mysqli=new mysqli($mysql_host, $user, $password, $database);
$query="select distinct name from animals";
$res=$mysqli->query($query);
while ($row=$res->fetch_assoc()) {
    print "{$row['name']}";
echo "</li>", "<li>";

I can get all the animals to print as list items with no problem. Now I want to use php to print out the animal that I click on. However, when I call this php file shown below, only the first list item will print properly. Please help

<?php
include_once 'config.inc';
$mysqli=new mysqli($mysql_host, $user, $password, $database);
$query="select distinct name from animals";
$res=$mysqli->query($query);
$row=$res->fetch_assoc(); 
echo "{$row['name']} selected";

Answer 1

Try like this :

if ($res = $mysqli->query($query)) {
   while ($row = mysqli_fetch_assoc($res)) {
        echo $row['name'];
    }
}

Answer 2

I am not sure whether my answer is true or not, I am new in PHP, too.

Could you please try this one?

$query = "SELECT distinct name FROM animals";
$query_result = $sqli->query($query);
$query_row = $query_result->fetch_assoc();
$new = $query_row['name'];
echo $new;
