What MySQL syntax is used in the code snippet to select entries with the same IP address?

To select entries with the same IP address in MySQL, you can use the GROUP BY clause along with the HAVING clause. The GROUP BY clause groups the rows that have the same IP address, and the HAVING clause filters the groups to only show those with more than one entry. This allows you to select entries with the same IP address.

// Assuming $db is your database connection

$query = "SELECT ip_address, COUNT(*) as count FROM your_table_name GROUP BY ip_address HAVING count > 1";
$result = mysqli_query($db, $query);

while($row = mysqli_fetch_assoc($result)){
    echo "IP Address: " . $row['ip_address'] . " has " . $row['count'] . " entries with the same IP address. <br>";
}
