How can PHP JOIN be used to retrieve the group name based on the group ID in the database query?

To retrieve the group name based on the group ID in a database query using PHP JOIN, you can use a SQL query that joins the two tables on the group ID. This will allow you to fetch the group name associated with the group ID from the database. 

<?php
// Assuming you have a database connection established

$group_id = 1; // Example group ID

$query = "SELECT groups.group_name
          FROM groups
          JOIN users ON groups.group_id = users.group_id
          WHERE users.group_id = $group_id";

$result = mysqli_query($connection, $query);

if(mysqli_num_rows($result) > 0) {
    $row = mysqli_fetch_assoc($result);
    $group_name = $row['group_name'];
    echo "Group Name: " . $group_name;
} else {
    echo "Group not found";
}

mysqli_close($connection);
?>
