Are there best practices for handling large amounts of data in PHP, specifically with CSV files?

When handling large amounts of data in PHP, specifically with CSV files, it is important to use efficient techniques to prevent memory exhaustion and optimize performance. One common approach is to read and process the CSV file line by line instead of loading the entire file into memory at once. This can be achieved using PHP's built-in functions like fopen, fgetcsv, and fclose. 

$filename = 'large_data.csv';

if (($handle = fopen($filename, 'r')) !== false) {
    while (($data = fgetcsv($handle)) !== false) {
        // Process each row of data here
    }
    fclose($handle);
} else {
    echo "Error opening file";
}
