How can mismatched column counts between a CSV file and a MySQL database table be resolved during import?

When dealing with mismatched column counts between a CSV file and a MySQL database table during import, one solution is to manually map the columns from the CSV file to the corresponding columns in the database table. This can be done by specifying the columns to import and matching them with the appropriate database table columns. 

// Connect to MySQL database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Specify columns to import from CSV file and map them to corresponding database table columns
$csv_columns = array('column1', 'column2', 'column3');
$db_columns = array('db_column1', 'db_column2', 'db_column3');

// Import data from CSV file
if (($handle = fopen("data.csv", "r")) !== FALSE) {
    while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
        $sql = "INSERT INTO table_name (".implode(',', $db_columns).") VALUES ('".implode("','", $data)."')";
        if ($conn->query($sql) === TRUE) {
            echo "Record inserted successfully";
        } else {
            echo "Error: " . $sql . "<br>" . $conn->error;
        }
    }
    fclose($handle);
} else {
    echo "Error: Unable to open file";
}

// Close MySQL connection
$conn->close();
