How can you ensure that mysql_fetch_array only returns one record?

To ensure that mysql_fetch_array only returns one record, you can limit the result set using the LIMIT clause in your SQL query. This will restrict the query to only return a single record from the database. Additionally, you can use a WHERE clause to specify specific criteria for fetching the record. 

$query = "SELECT * FROM table_name WHERE condition_column = 'condition_value' LIMIT 1";
$result = mysql_query($query);

if ($row = mysql_fetch_array($result)) {
    // Process the fetched record here
} else {
    // No record found
}
