Read multiple entries with a Where clause - select

Question

I tried to build a User search function but i ran into a problem a while ago. My function, which looks like this:
"Select id, username FROM users WHERE username LIKE '%search%'"
Is showing me only the user Janamaris ( userlist is a bit lower )
but as you see jns.drws has also a j in his username ( J = $search ).
So my Problem now i want to show all users with a J in his/her username
So how can i get all users with WHERE?
My Signed Users are [id, username]
Tolkosino
47, Janamaris
48, TheCrazyMan
49, jns.drws

Beispiel einer Foreach Schleife bzw. While Schleife Posten?
English: Can someone post an example of a foreach e.g. while loop?
The sql is fine and will get all rows you need:
"Select id, username FROM users WHERE username LIKE '%search%'"
If you have problems with upper/lower case then read this:

Example with while
if($result = $mysqli->query($sql)){
if(is_object($result)){
while($row = $result->fetch_assoc()){
echo "<div id=\"content-b\">";
echo "<p class=\"usrsrch\">User ID : " . $row['id'] . "";
echo "<br>";
echo "<p class=\"usrsrch\">Username : . $row['username'] . "";
echo "</div>";
}
} else {
echo 'nix gefunden';
}
}
