PHP & Symfony Expertise
Why PHP remains strategic in 2026
PHP powers more than 75% of the application web worldwide, from WordPress up to French banking platforms. Version 8.3, released in November 2023, and 8.4 in November 2024, radically shifted the perception of the language: performance doubled compared to PHP 7, strict typing, readonly properties, enums, async through Fibers, and a Composer ecosystem that remains one of the most mature on the market.
In 2026, the real question is no longer "should I pick PHP", but "how do I leverage PHP correctly". A Symfony 7 application with Doctrine ORM, API Platform 4, PHPStan level 9 and a serious GitHub Actions CI has nothing to envy to a Node or Go stack. Our team operates on business applications where robustness, ten-year maintainability and regulatory compliance take precedence over technological hype.
Our approach
Our boutique applies an industrial methodology to PHP development, not an artisanal one.
- Strict typing everywhere. Systematic
declare(strict_types=1), PHPStan level 9 from the very first commit, no tolerance for unjustifiedmixed. Type errors are bugs, not a lifestyle. - DDD architecture with bounded contexts. Clear separation between domain, application, infrastructure. Dependencies point inward. Doctrine remains an implementation detail, not a backbone.
- Non-negotiable automated tests. PHPUnit for the domain, Behat for business scenarios, Pest when the BDD style helps. Target coverage above 70% on the business layer, 100% on critical invariants.
- CI/CD operational from day 1. GitHub Actions or GitLab CI, four-stage pipeline (lint, static analysis, tests, build), no merge without green light. Pipeline runtime under 10 minutes maintained as an SLI.
- Short pull requests, reviewed within 24 hours. Any PR exceeding 400 lines is split. Reviewing is a knowledge transfer moment, not a formality.
- Documentation through ADRs. Every structural decision (ORM, queue, authentication) is logged in an Architectural Decision Record versioned alongside the code.

PHP-specific FAQ
Is PHP 8.3 really comparable to Node.js or Go in performance? On classic web applications (I/O bound, with OPcache and JIT enabled), PHP 8.3 holds the load of Node for the majority of cases. Beyond 10,000 requests per second on a CPU-bound endpoint, Go or Rust become relevant. For 95% of back-offices and business platforms, PHP remains the best ratio of development velocity to robustness.
Symfony or Laravel: how to choose? Symfony wins as soon as the team practices DDD, the project will exceed 5 years of life, or contractual rigor prevails (banking, insurance, healthcare). Laravel wins for tight time-to-market, a more junior team, or a product with high functional turnover. Our team masters both with no ideological preference.
Is it still worth maintaining PHP 7 in 2026? PHP 7.4 has been end of life since November 2022, with no official security patches. Keeping a PHP 7 application in production exposes you to uncorrected CVEs on zlib, openssl, ICU. Our recommendation is to plan migration within 12 months at most. See our migration service.
Is PHPStan level 9 or 10 achievable on a legacy project? Yes, through staged progress. We start at the level actually supported by the code, then raise one notch each sprint. Rector automates the typing transformations. On a 200,000-line codebase, going from level 0 to level 8 takes 3 to 6 months depending on initial quality.
What is your position on API Platform versus plain Symfony? API Platform dramatically accelerates CRUD and standardization (JSON-LD, OpenAPI, pagination). For a domain-oriented API with rich business logic, we combine API Platform as a façade and pure business handlers, unit tested. We avoid "magical State Providers" on critical flows.
