How can you optimize the code provided to efficiently read and process data from a .csv file in PHP?

The code can be optimized by using PHP's built-in functions like fgetcsv() to efficiently read and process data from a .csv file. By using these functions, we can avoid manually parsing the file line by line and handle the data in a more streamlined manner. 

<?php
// Open the CSV file for reading
$csvFile = fopen('data.csv', 'r');

// Read and process each row of the CSV file
while (($data = fgetcsv($csvFile)) !== false) {
    // Process the data from the current row
    // For example, you can access specific columns using $data[index]
    echo $data[0] . ', ' . $data[1] . "\n";
}

// Close the CSV file
fclose($csvFile);
?>
