What is the best way to process CSV data from a form using PHP?

When processing CSV data from a form using PHP, it is best to first upload the CSV file using a form input of type file, then use PHP functions like fopen, fgetcsv, and fclose to read and parse the CSV data. Once the data is parsed, you can perform any necessary validation, manipulation, or storage operations. 

if(isset($_FILES['csv_file'])){
    $file = $_FILES['csv_file']['tmp_name'];
    $handle = fopen($file, "r");

    while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
        // Process each row of CSV data here
        // Example: echo $data[0]; // Access first column of each row
    }

    fclose($handle);
}
