PHP development is the design, build, upgrade and support of web software written in PHP, including portals, e-commerce stores, APIs, SaaS back ends and WordPress or Drupal sites. SynconAI builds new PHP applications, takes over existing ones, moves them to a supported PHP 8 release, and supplies PHP engineers who join client teams, for organizations in the United States, Australia and worldwide. - PHP is a server-side programming language for the web. It runs WordPress, Drupal and many stores, portals and SaaS back ends. - Each PHP release gets security fixes for a fixed window. PHP 8.1 ended on December 31, 2025 and PHP 8.2 ends on December 31, 2026. - Modern PHP is built with frameworks such as Laravel and Symfony, with Composer for packages and PHPUnit, Pest and PHPStan for quality. ## PHP development services - New PHP applications: Portals, SaaS back ends and internal tools on Laravel or Symfony. - APIs: Documented REST APIs for mobile apps, partners and front ends. - CMS and e-commerce: WordPress, Drupal, WooCommerce and Adobe Commerce builds and fixes. - PHP upgrades: PHP 7.4, 8.1 or 8.2 moved to 8.4 or 8.5, with libraries updated. - Performance and security: Slow pages, heavy queries and outdated plugins found and fixed. - Testing: PHPUnit or Pest tests and PHPStan checks in your pipeline. - Salesforce integration: Web forms, orders and portals connected through Salesforce APIs. - Team extension: PHP engineers who work in your repos, rituals and tools. ## Where are you with PHP? Question: What state is your PHP application in today? - Not built yet: A new PHP build. You need a portal, store, API or SaaS back end on a current PHP release. - Design agreed before code - Laravel or Symfony chosen for fit - Tests and static analysis from the first sprint - Built by an agency or a team that left: Taking over an application. A PHP site or app runs your business and nobody left knows it well. - Code, plugin and hosting review first - Deploy steps and backups written down - Fixes ranked by risk - Running on an old PHP: Upgrading or modernizing. It works, but runs on PHP 7.4, 8.1 or 8.2, or on a framework version that no longer gets fixes. - Code scanned for breaking changes - Upgrade done in tested steps - Framework and plugins upgraded too Outcome: A PHP application on a supported release, with tests, documentation and a team that can run it ## What do our PHP development services include? From custom applications to the CMS and stores your marketing team runs. - New PHP applications: Portals, SaaS back ends and internal tools on Laravel or Symfony. - APIs: Documented REST APIs for mobile apps, partners and front ends. - CMS and e-commerce: WordPress, Drupal, WooCommerce and Adobe Commerce builds and fixes. - PHP upgrades: PHP 7.4, 8.1 or 8.2 moved to 8.4 or 8.5, with libraries updated. - Performance and security: Slow pages, heavy queries and outdated plugins found and fixed. - Testing: PHPUnit or Pest tests and PHPStan checks in your pipeline. - Salesforce integration: Web forms, orders and portals connected through Salesforce APIs. - Team extension: PHP engineers who work in your repos, rituals and tools. ## The PHP stack we work with From the CMS your editors see to the checks that run on every change. - CMS and commerce (What the site runs on): WordPress, Drupal, WooCommerce, Adobe Commerce - Application frameworks (How custom code is built): Laravel, Symfony, Doctrine - Runtime and packages (What the code runs on): PHP 8.4, PHP 8.5, Composer - Testing and analysis (How each release is checked): PHPUnit, Pest, PHPStan ## Which PHP version should we upgrade to? PHP 7.4 ended in November 2022 and PHP 8.1 on December 31, 2025. PHP 8.2 stops getting security fixes on December 31, 2026. Today: PHP 7.4, 8.1 or 8.2 - PHP 8.5, Move to the current release: PHP 8.5, released November 2025, gets security fixes to December 2029. Best when your libraries and plugins already support it. - PHP 8.4, Move to PHP 8.4: Supported to December 2028, a steady target when an older library is not ready for 8.5. Best for large codebases with many dependencies. - Current framework, Upgrade the framework too: Laravel 11 ended in March 2026 and Laravel 12 security fixes end in February 2027. We plan PHP and framework upgrades together. Best when the framework is behind as well. ## How can we work together on PHP? Three ways to engage. Each starts with a written proposal agreed before work begins. - Fixed-scope project, A defined PHP deliverable, built and handed over. - We direct the work against agreed milestones - Priced per milestone in the proposal - Working code, tests and documentation - Fits a new build, an upgrade or a rescue - Dedicated team, A PHP team that runs your site or product with you. - Our lead runs delivery, you set priorities - Billed on a monthly plan - Engineers, a lead and testing as one unit - Fits ongoing work without an in-house team - Team extension, PHP engineers added to the team you already run. - Your managers direct the day-to-day work - Billed monthly for each engineer - Vetted engineers; we handle employment and replacement - Fits a backlog bigger than your current team ## How does a PHP engagement start? Five steps from the first call to delivery. - Brief: Free 60-minute review of your site or app; Goals, constraints and access agreed under NDA - Match or design: Engineers matched and interviewed by you; Or a scope and milestone plan written - Start: Hosting, repos and staging set up; Codebase walkthrough and a first task - Build and review: Sprints with code review on every change; Tests and a demo each sprint - Hand over or continue: Runbooks and handover sessions; Or a monthly plan for support ## Cost and timing The first step is a free 60-minute architecture review of your PHP application setup, with a written plan you keep. Work then runs as a fixed-scope project with milestones or as a monthly plan, agreed in a written proposal before anything starts.
