How can PHP developers ensure that only the name of the other user is displayed in a messaging system template?

To ensure that only the name of the other user is displayed in a messaging system template, PHP developers can use a conditional statement to check if the user is the current user or the other user before displaying the name. This can be achieved by comparing the user IDs or usernames in the database to determine whose name should be displayed. 

<?php
// Assuming $currentUserId is the ID of the current user and $otherUserId is the ID of the other user
if ($message['sender_id'] == $currentUserId) {
    echo "You";
} else {
    echo $otherUser['name'];
}
?>
