How can the PHP code snippet provided in the forum be optimized for better performance when handling large CSV files?

Large CSV files can cause performance issues when processing them in PHP due to memory constraints. One way to optimize the code is to read the file line by line instead of loading the entire file into memory at once. By using fopen and fgets functions, we can efficiently handle large CSV files without consuming excessive memory. 

$filename = 'large_file.csv';
if (($handle = fopen($filename, 'r')) !== false) {
    while (($data = fgetcsv($handle)) !== false) {
        // Process each row of data here
    }
    fclose($handle);
}
