What are some best practices for efficiently searching and processing data in CSV files using PHP?

Searching and processing data in CSV files efficiently in PHP involves using the built-in functions like fgetcsv() to read the file line by line, and then applying filters or operations on the data. It is important to optimize the search and processing algorithms to handle large CSV files efficiently. 

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

// Loop through each row in the CSV file
while (($data = fgetcsv($csvFile)) !== false) {
    // Process the data here, for example:
    $name = $data[0];
    $email = $data[1];
    
    // Perform search or processing operations here
}

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