What are the potential risks of using keywords like "key" as field names in MySQL databases when working with PHP?

Using keywords like "key" as field names in MySQL databases can lead to conflicts and errors in PHP code when querying the database. To avoid this issue, it is recommended to use backticks (`) around the field names in MySQL queries to ensure they are treated as identifiers rather than keywords. 

$query = "SELECT `key` FROM table_name";
$result = mysqli_query($connection, $query);

if ($result) {
    // Process the query result
} else {
    // Handle the error
}
