PHP in 2026: a still central language, behind the screens

According to W3Techs surveys on web server technologies, PHP remains widely used backend language on public sites, ahead of Node.js and Python. This position stems from the CMS ecosystem built on PHP (WordPress, Drupal, Joomla, Magento, PrestaShop, Symfony and Laravel) and from LAMP stack maturity. In French-speaking Switzerland, web agencies, e-commerce, media platforms, scale-ups and large organisations still extensively use PHP, either on custom Laravel or Symfony applications or around WordPress and Drupal for their sites.

The challenge for a PHP developer in 2026 is no longer the “PHP vs other language” debate but practice modernisation: PHP 8.x brings major evolutions (strict typing, attributes, enums, JIT performance), Composer has become widely adopted dependency management tool, frameworks (Laravel, Symfony) structure architectures, and the MySQL/MariaDB ecosystem remains the database most paired with PHP.

The ITTA catalogue: PHP/MySQL from fundamentals to advanced

PHP/MySQL Fundamentals

PHP MySQL Fundamentals covers PHP syntax (variables, types, operators, conditions, loops), functions and control structures, strings and arrays, form and HTTP request handling, MySQL database access with PDO, session and cookie management, file upload, email sending, and first code structuring best practices. This is the natural entry for any profile starting PHP.

PHP/MySQL Advanced

PHP MySQL – Advanced deepens object-oriented programming (classes, inheritance, interfaces, traits, namespaces), design patterns, MVC architecture, application security (SQL injection, XSS, CSRF, security headers), performance optimisation (cache, queries, profiling), Composer and dependency management, introduction to Laravel and Symfony frameworks, and testing and deployment best practices.

The typical path for a complete web developer is to follow both modules in order, leaving a few weeks between sessions to assimilate the Fundamentals block on a personal or professional project.

PHP/MySQL in the ITTA development ecosystem

PHP fits a broader catalogue. The programming languages sub-domain groups PHP, Python, Java, C#, JavaScript and C++ training. The database design and development sub-domain brings advanced SQL skills and modelling. For PHP developers moving towards modern architectures, the cross with DevOps, security and cloud sub-domains is common.

On the publisher side, PHP developers often cross paths with WordPress (site management, plugins, security) and Open Source (grouping libre technologies). PHP and MySQL/MariaDB being historically linked, the Fundamentals course includes the MySQL pillar.

Profiles training and career perspectives

Our PHP audience is varied. Most represented profile: junior to mid-level web developers structuring their practice. We also see web integrators moving to backend, system administrators wanting to understand and maintain existing PHP applications, WordPress CMS profiles wanting to customise beyond plugins, and IT career changers targeting a first developer role. More rarely, developers from other languages (Python, Java) intervening on legacy PHP applications.

Career perspectives are varied: backend web developer, full stack PHP+JavaScript developer, advanced WordPress integrator, Laravel or Symfony developer, PHP application architect. On the MySQL side, skills cover basic administration, query optimisation and modelling, complementing transverse SQL skills.

PHP trends in 2026

PHP 8.3 and the upcoming PHP 8.4 consolidate language modernisation: strict typing, enums, attributes, readonly properties, JIT performance. Laravel stands out as the major framework, followed by Symfony for enterprise applications. WordPress remains dominant on the CMS side, with rising headless WordPress (REST API and GraphQL). On the tooling side, Composer is universal, PHPStan and Psalm structure static analysis, PHPUnit and Pest dominate testing. On the database side, MySQL 8 and MariaDB 11 bring major evolutions (JSON, analytical windows, performance).

PHP/MySQL sessions in Geneva, Lausanne and virtual

Our PHP sessions are available in Geneva, Lausanne and interactive virtual classroom with an active PHP developer. Each session includes labs on a training LAMP environment, code to write from the first hours and a progressive thread project. Customised corporate training is common, especially for web agency teams and scale-ups looking to upskill together on Laravel or Symfony starting from a solid PHP/MySQL base.

PHP/MySQL FAQ

Do I need HTML/CSS/JavaScript before training on PHP?

An HTML/CSS base helps enormously, because PHP is traditionally used to generate HTML server-side. JavaScript is not a prerequisite for starting PHP but becomes indispensable to move to full stack. Our Fundamentals course assumes you have basic HTML exposure.

PHP or Node.js or Python for a new web project?

It depends on context. PHP remains the most pragmatic choice if you work around a CMS (WordPress, Drupal) or a mature PHP framework (Laravel, Symfony). Node.js suits real-time or very JavaScript-front-oriented applications. Python is preferred when there is a data, AI or scientific dimension. Our trainers help you objectify the choice based on your project.

Should I learn Laravel or Symfony, and in what order?

Laravel is generally perceived as more accessible to start a project, with a very large community and progressive ramp-up. Symfony is more structuring and more used on large enterprise applications. Many developers learn both. Our Advanced course introduces both frameworks and gives the basis to choose based on context.

MySQL or MariaDB, and how does PostgreSQL position?

MySQL and MariaDB are quasi-interchangeable for the vast majority of PHP applications. Linux distributions have mostly shifted to MariaDB. PostgreSQL is more advanced on certain SQL features and is preferred for complex applications. Our PHP/MySQL catalogue covers application use. To go further on databases, see the dedicated sub-domain.

What are the most frequent security risks in PHP?

SQL injection (poorly handled with mysqli without preparation), Cross-Site Scripting (XSS) on unescaped HTML output, CSRF on unprotected forms, session management, poorly validated file upload. Our Advanced course covers these points in depth, with attack and defence demonstrations. Security is a topic of its own for any PHP developer in production.

PHP in production: what our trainers see in the field

Beyond the official programme, our PHP trainers share in class the field observations that make the difference between a functional PHP developer and a solid one. First point: code base quality. Too many production PHP applications suffer from massive technical debt (procedural and object-oriented mix, no tests, obsolete dependencies, security not reviewed). The Advanced course emphasises modern practices (PSR, Composer, autoloading, PHPUnit or Pest tests, PHPStan static analysis) to regain control on an application.

Second point: performance management. PHP 8 is natively fast, but a poorly architected application brings it to problematic response times. Best practices (opcache enabled, optimised queries with EXPLAIN, Redis or Memcached caching, lazy loading of Eloquent or Doctrine relationships) are essential. The Advanced course covers these topics with concrete cases.

Third point: security. Beyond classics (SQL injection, XSS, CSRF), current topics involve secrets management (never in Git repo, always environment variable or secret manager), server-side input validation even when front already validates, fast Composer dependency updates for CVEs, and stack hardening (PHP-FPM, Nginx, MySQL, TLS configuration). These topics are systematically addressed in the Advanced course because they condition application robustness in production.
