Are there any best practices for handling large file uploads in PHP?

Handling large file uploads in PHP can be challenging due to limitations such as server memory and execution time. One best practice is to increase the upload_max_filesize and post_max_size values in your php.ini file to allow for larger file uploads. Additionally, consider using chunked file uploads or third-party libraries like Dropzone.js to handle large file uploads more efficiently. 

// Increase upload_max_filesize and post_max_size values in php.ini
ini_set('upload_max_filesize', '20M');
ini_set('post_max_size', '25M');

// Handle large file uploads using PHP
if ($_SERVER['REQUEST_METHOD'] == 'POST' && !empty($_FILES['file'])) {
    $file = $_FILES['file'];
    
    if ($file['error'] === UPLOAD_ERR_OK) {
        $uploadDir = 'uploads/';
        $uploadFile = $uploadDir . basename($file['name']);

        if (move_uploaded_file($file['tmp_name'], $uploadFile)) {
            echo 'File uploaded successfully!';
        } else {
            echo 'Failed to upload file.';
        }
    } else {
        echo 'Error uploading file.';
    }
}
