What are the best practices for creating and managing file uploads in PHP to prevent errors like displaying only "Array"?

When handling file uploads in PHP, the issue of displaying only "Array" typically occurs when trying to directly output an array variable. To prevent this error, you should ensure that you are accessing the correct array key that contains the file information, such as the file name or file size. By properly referencing the array key, you can display the desired file upload information without encountering the "Array" display issue. 

// Example code snippet to handle file uploads and prevent displaying only "Array"

if ($_FILES['file']['error'] === UPLOAD_ERR_OK) {
    $file_name = $_FILES['file']['name'];
    $file_size = $_FILES['file']['size'];
    
    // Process the file upload further or display the file information
    echo "File Name: " . $file_name . "<br>";
    echo "File Size: " . $file_size . " bytes";
} else {
    echo "Error uploading file. Please try again.";
}
