Are there any best practices in PHP for handling CSV files and extracting specific data from them?

When handling CSV files in PHP, it is essential to use the built-in functions provided by PHP for efficient and reliable data extraction. One common approach is to use the fgetcsv() function to read each line of the CSV file as an array, allowing you to access specific columns or data elements easily. 

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

// Loop through each line of the CSV file
while (($data = fgetcsv($csvFile)) !== false) {
    // Extract specific data elements from the CSV row
    $column1 = $data[0]; // Accessing the first column
    $column2 = $data[1]; // Accessing the second column
    
    // Process or output the extracted data as needed
    echo "Data from column 1: $column1\n";
    echo "Data from column 2: $column2\n";
}

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