In the context of PHP web development, what are the advantages and disadvantages of storing image files in a database versus a file system?

Storing image files in a database can simplify data management and ensure data integrity, but it can also lead to slower performance and increased database size. On the other hand, storing image files in a file system can improve performance and scalability, but it may require additional effort to manage and synchronize with the database.

// Storing image files in a file system example
$targetDirectory = "uploads/";
$targetFile = $targetDirectory . basename($_FILES["fileToUpload"]["name"]);

if (move_uploaded_file($_FILES["fileToUpload"]["tmp_name"], $targetFile)) {
    echo "The file ". basename( $_FILES["fileToUpload"]["name"]). " has been uploaded.";
} else {
    echo "Sorry, there was an error uploading your file.";
}
