Learn how to reduce load times, improve scalability, and cache smartly using Symfony’s built-in HTTP caching tools, Edge Side Includes (ESI), and the Varnish reverse proxy.
HTTP caching sits between your users and your backend, serving popular pages directly from memory without hitting PHP. With proper caching headers, you can reduce server load and deliver content in milliseconds instead of seconds.
Symfony is built around a simple but powerful idea: everything is a bundle. A bundle is a self-contained package of code — controllers, entities, services, and templates — that can be reused across multiple projects.
In this guide, we’ll walk through how bundles work, how to create your own, and how they fit into a modern Symfony 7 application.
This will be an ongoing list of different Customer Relation Management system with short comments on each.
As artificial intelligence produces more and more online content, it’s becoming harder to tell what’s written by humans and what’s generated by machines. It’s convenient and efficient — but it also comes with a serious risk: the gradual loss of quality, depth, and diversity across the web.
When starting a new PHP project, Composer is the foundation of modern PHP development. It automates dependency management, handles autoloading, and ensures your codebase remains consistent across environments.
But with more than 350,000 packages on Packagist, it can be overwhelming to find the right tools. Below is a curated list of the 10 most useful Composer packages every developer should know in 2025.
If you come to Symfony from Laravel, Drupal, or Node.js, one of the first concepts you meet is the bundle. It looks a lot like a plugin or module — until you start working with it.
Bundles embody a design philosophy that’s distinctively Symfony: composition over inheritance, configuration over convention, and strict separation of concerns. Understanding this idea is key to grasping why Symfony applications remain maintainable at scale.
The PHP ecosystem has evolved dramatically over the last decade. Frameworks like Laravel, Slim, and CodeIgniter have matured, while newcomers such as Spiral and Hyperf are introducing async paradigms and reactive programming.
Yet, amidst all this change, Symfony continues to be the gold standard for modularity, stability, and architectural discipline. It’s not the most lightweight or trendy framework, but it remains the one that other frameworks borrow from — quite literally, in Laravel’s case.
Artificial Intelligence has become an integral part of the modern developer's workflow — from code suggestions to natural language search and data enrichment. But most of these tools come at a cost: constant internet connections, cloud-based APIs, and corporate monitoring of every token you generate.
Many developers (myself included) have started to ask: what if we could bring AI back under our own control? Luckily, in 2025, open source models and local inference engines are finally good enough to make that vision real.
I have started creating some projects in php with the Symfony framework. There are a great tool called thw webprofiler which helps you get all sorts of debug information about the current page you are viewing in you symfony app.
Recently I stumpled upon a problem where the toolbar didnt show up on my pages. It turned out that the reason was that my site run in a local https mode but the urls for the webprofiler was rendered as http only. This ofcourse prevented the urls to load proberbly.
