How can PHP code be optimized to prevent errors and improve efficiency when checking and processing CSV files for database import?

To optimize PHP code for checking and processing CSV files for database import, it is important to handle errors gracefully and efficiently. This can be achieved by implementing proper error handling, using efficient CSV parsing functions, and optimizing database queries for bulk inserts to improve performance. 

<?php

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

// Check if the file was opened successfully
if ($file === false) {
    die('Error opening file');
}

// Read and process each row from the CSV file
while (($data = fgetcsv($file)) !== false) {
    // Process the data and insert into the database
    // Perform necessary validations and sanitization
}

// Close the file after processing
fclose($file);

?>
