How can PHP developers ensure efficient data extraction from CSV files?

PHP developers can ensure efficient data extraction from CSV files by using the built-in functions like fgetcsv() to read the file line by line and parse each row into an array. They can also utilize functions like str_getcsv() to parse a CSV string into an array. Additionally, developers can optimize the process by using proper error handling and memory management techniques. 

// Open the CSV file for reading
$handle = fopen('data.csv', 'r');

// Loop through each row and extract data
while (($data = fgetcsv($handle)) !== false) {
    // Process the data here
    print_r($data);
}

// Close the file
fclose($handle);
