What are the advantages of using associative names for CSV column headers in PHP compared to numerical indexes?

When using associative names for CSV column headers in PHP, it becomes easier to reference specific columns by their names rather than numerical indexes. This makes the code more readable and maintainable, as it is clearer what each column represents. Additionally, associative names can help prevent errors when accessing specific columns, as it eliminates the risk of misinterpreting numerical indexes. 

// Using associative names for CSV column headers
$csvData = array_map('str_getcsv', file('data.csv'));
$headers = array_shift($csvData);

foreach ($csvData as $row) {
    $rowData = array_combine($headers, $row);
    
    // Accessing specific columns by their names
    $name = $rowData['Name'];
    $age = $rowData['Age'];
    
    // Process data...
}
