What is the best method to upload a CSV file in PHP and extract its contents for further processing?

To upload a CSV file in PHP and extract its contents for further processing, you can use the built-in functions like move_uploaded_file() to upload the file and fopen() to open and read the file. Then, you can use fgetcsv() function to read each row of the CSV file and process its contents as needed. 

<?php
if(isset($_FILES['file'])){
    $file = $_FILES['file'];

    // Upload the file
    $uploadDir = 'uploads/';
    $uploadFile = $uploadDir . basename($file['name']);
    move_uploaded_file($file['tmp_name'], $uploadFile);

    // Open the file
    $handle = fopen($uploadFile, 'r');

    // Read and process the CSV file
    while (($data = fgetcsv($handle, 1000, ',')) !== FALSE) {
        // Process each row of the CSV file
        print_r($data);
    }

    // Close the file
    fclose($handle);
}
?>
