What are the advantages of using foreach loops in PHP for iterating over CSV data compared to traditional for loops?

When iterating over CSV data in PHP, using foreach loops can offer a more concise and readable way of accessing each row of data compared to traditional for loops. Foreach loops automatically handle the iteration over the array of data, making it easier to work with the individual rows without needing to manage an index variable manually. Additionally, foreach loops can be more efficient as they only iterate over the elements in the array, rather than needing to calculate the array length and incrementing an index variable. 

// Read CSV file into an array
$csvData = array_map('str_getcsv', file('data.csv'));

// Using foreach loop to iterate over each row of CSV data
foreach ($csvData as $row) {
    // Process each row of data
    echo implode(', ', $row) . "\n";
}
