How can developers optimize their PHP code to efficiently handle file uploads and storage, considering factors like database size limits and server configurations?

Developers can optimize their PHP code for file uploads and storage by implementing proper file validation, limiting file sizes, and utilizing efficient storage methods. They can also consider using external storage solutions like Amazon S3 or Google Cloud Storage to offload file storage from the server. Additionally, developers should regularly clean up old or unused files to prevent database size limits from being reached. 

// Example code snippet for optimizing file uploads and storage in PHP

// Set maximum file size limit
$maxFileSize = 10 * 1024 * 1024; // 10MB

// Validate file type and size before uploading
if ($_FILES['file']['size'] <= $maxFileSize && in_array($_FILES['file']['type'], ['image/jpeg', 'image/png'])) {
    // Move uploaded file to storage location
    move_uploaded_file($_FILES['file']['tmp_name'], 'uploads/' . $_FILES['file']['name']);
    echo 'File uploaded successfully!';
} else {
    echo 'Invalid file type or size.';
}
