CSV Processing

CSV processing refers to handling CSV (Comma Separated Values) files in PHP, an operation significantly useful for managing tabular data. PHP provides a few key functions to handle CSV files effectively. For example, fgetcsv() allows you to read CSV file line by line, fputcsv() lets you write line by line into a CSV file, and str_getcsv() allows you to parse a CSV string into an array. A quick example of reading a CSV file:

if (($handle = fopen("sample.csv", "r")) !== FALSE) {
    while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
        print_r($data);
    }
    fclose($handle);
}

In this snippet, PHP reads through each line of the sample.csv file, converting each into an array with fgetcsv(). You can study more about CSV processing in PHP via the official PHP documentation.
