Laravel's onEachSide method offers granular control over the pagination links displayed near the current page, enhancing navigation clarity. Instead of relying on the default link count, you can tailor the display to suit your application's specific needs.
This is especially beneficial for applications handling datasets of varying sizes. For larger datasets, you might want to show more navigation options; for smaller ones, a cleaner, less cluttered interface is preferable.
Here's how to implement adaptive pagination:
<?php namespace AppHttpControllers;
use AppModelsArticle;
use IlluminateHttpRequest;
class ArticleController extends Controller
{
public function index(Request $request)
{
$perPage = $this->determinePerPage($request);
$articles = Article::latest()
->withCount('comments')
->paginate($perPage);
$linksToShow = $this->calculateVisibleLinks($articles);
return view('articles.index', compact('articles', 'linksToShow'));
}
private function determinePerPage(Request $request): int
{
return $request->query('show', 10);
}
private function calculateVisibleLinks($paginator): int
{
$totalPages = $paginator->lastPage();
// Dynamically adjust visible links based on total pages
return match(true) {
$totalPages > 20 => 3,
$totalPages > 10 => 2,
default => 1
};
}
}
In your blade template (articles.index.blade.php):
{{ $articles->onEachSide($linksToShow)->links() }}
This results in a dynamic pagination display:
<code>// ~50 articles (5 pages) ? 1 2 3 4 5 ? // ~150 articles (15 pages) ? 1 ... 4 5 6 7 8 ... 15 ? // ~250 articles (25 pages) ? 1 ... 4 5 6 7 8 9 10 ... 25 ?</code>
The onEachSide method, combined with dynamic link calculation, creates a more user-friendly and adaptable pagination experience.

How can you handle file uploads securely in PHP?
Jun 19, 2025 am 01:05 AM
To safely handle file uploads in PHP, the core is to verify file types, rename files, and restrict permissions. 1. Use finfo_file() to check the real MIME type, and only specific types such as image/jpeg are allowed; 2. Use uniqid() to generate random file names and store them in non-Web root directory; 3. Limit file size through php.ini and HTML forms, and set directory permissions to 0755; 4. Use ClamAV to scan malware to enhance security. These steps effectively prevent security vulnerabilities and ensure that the file upload process is safe and reliable.
What are the differences between == (loose comparison) and === (strict comparison) in PHP?
Jun 19, 2025 am 01:07 AM
In PHP, the main difference between == and == is the strictness of type checking. ==Type conversion will be performed before comparison, for example, 5=="5" returns true, and ===Request that the value and type are the same before true will be returned, for example, 5==="5" returns false. In usage scenarios, === is more secure and should be used first, and == is only used when type conversion is required.
How can you interact with NoSQL databases (e.g., MongoDB, Redis) from PHP?
Jun 19, 2025 am 01:07 AM
Yes, PHP can interact with NoSQL databases like MongoDB and Redis through specific extensions or libraries. First, use the MongoDBPHP driver (installed through PECL or Composer) to create client instances and operate databases and collections, supporting insertion, query, aggregation and other operations; second, use the Predis library or phpredis extension to connect to Redis, perform key-value settings and acquisitions, and recommend phpredis for high-performance scenarios, while Predis is convenient for rapid deployment; both are suitable for production environments and are well-documented.
How do I perform arithmetic operations in PHP ( , -, *, /, %)?
Jun 19, 2025 pm 05:13 PM
The methods of using basic mathematical operations in PHP are as follows: 1. Addition signs support integers and floating-point numbers, and can also be used for variables. String numbers will be automatically converted but not recommended to dependencies; 2. Subtraction signs use - signs, variables are the same, and type conversion is also applicable; 3. Multiplication signs use * signs, which are suitable for numbers and similar strings; 4. Division uses / signs, which need to avoid dividing by zero, and note that the result may be floating-point numbers; 5. Taking the modulus signs can be used to judge odd and even numbers, and when processing negative numbers, the remainder signs are consistent with the dividend. The key to using these operators correctly is to ensure that the data types are clear and the boundary situation is handled well.
