Is it recommended to store images in a database or in a directory outside the document root in PHP applications?

Storing images in a database can lead to performance issues and increased database size. It is recommended to store images in a directory outside the document root to improve performance and reduce the load on the database. By storing images in a directory outside the document root, you can easily access and serve them through PHP without impacting the database. 

// Example code to store images in a directory outside the document root
$image = $_FILES['image']['name'];
$target_dir = "/path/to/image/directory/";
$target_file = $target_dir . basename($image);

if (move_uploaded_file($_FILES['image']['tmp_name'], $target_file)) {
    echo "Image uploaded successfully.";
} else {
    echo "Failed to upload image.";
}
