if statement multiple conditions for id - php

Question

I have a database table that is called roles. and it contains 5 roles and has id from 1 to 5, I have gotten the code below to work with 1 id only but want to add more without re using the entire block. so if id equals 3,4,5 show the link. can I add multiple id's in the if?
while ($row = mysqli_fetch_assoc($result)) {
$RoleID = $row['RoleID'];
if ($RoleID == 3) {
echo '<li><span>Admin Area</span></li>';
}
}

Answer 1

I guess you can use in_array:
$admin_array = [3,4,5];
while ($row = mysqli_fetch_assoc($result)) {
if (in_array($row['RoleID'], $admin_array) {
echo '<li><span>Admin Area</span></li>';
}
}

Answer 2

Hope below code will help you
I have used in_array() function
while ($row = mysqli_fetch_assoc($result)) {
$RoleID = $row['RoleID'];
if (in_array($RoleID,array(3,4,5))) {
echo '<li><span>Admin Area</span></li>';
}
}

Something that will give some added flexibility when say you want an id to do something similar but maybe end in the same way is to use a switch case.
while ($row = mysqli_fetch_assoc($result)) {
switch($row['RoleID']) {
case 1:
//Id 1 logic only
break;
case 2:
//Id 2 logic only
break;
case 3:
//Without a break it will fall through.
//Nice because if for some reason you need
//custom for individual id do it with no break
case 4:
case 5:
echo '<li><span>Admin Area</span></li>';
break;
default:
//Do something here for instances when a ROLE ID is not found
}
}
