Keep business workflows working." image: "https://wavect.io/img/general/bak/open_graph_preview.jpg" --- PHP & Symfony Development # Change the PHP workflow without losing the rules it carries. The difficult part of an established PHP application is often a rule scattered across controllers, forms and scheduled jobs. We make the affected workflow understandable, then change it in a sequence the team can review and release. THE ENGAGEMENT ## Trace the workflow before changing its structure. 1. **Reproduce the behavior** Identify routes, jobs, dependencies and data touched by the change. 2. **Separate the responsibilities** Make validation, authorization and business effects reviewable. 3. **Prove the release path** Exercise retries, compatibility and recovery with representative inputs. DIRECT ANSWER Wavect extends and improves existing PHP/Symfony applications, including business logic, dependency compatibility and asynchronous work. We start with the running workflow and agree what must remain stable before implementing changes. Best for - Businesses maintaining a PHP or Symfony application with important operational workflows - Teams needing a bounded feature, upgrade or reliability improvement Consider another approach - A standard content website that can be handled through the website service - An assumption that every PHP project needs Symfony or a full rewrite ## Start with the operation people cannot afford to lose Bring a concrete flow: an approval, invoice, account change or scheduled export. We inspect its PHP version, Composer dependencies, framework conventions and deployment setup. Existing tests and representative records help distinguish intentional behavior from accidental coupling. If the main problem is changing suppliers or recovering access, [Software Takeover](/services/software-takeover/) owns that first decision. ## Make the Symfony or PHP boundary explicit In Symfony, work may involve controllers, services, validation, authorization and persistence. In a smaller PHP application, those responsibilities still need identifiable owners, without adding a framework by default. We keep request handling separate from business effects where the change benefits from it. Security checks must cover the particular record and action, not merely whether somebody has logged in. ## A retried job must have an agreed business effect We inspect message identifiers, transaction timing, retry limits and the way operators see a failed job. For applications using [Symfony Messenger](https://symfony.com/doc/current/messenger.html), the transport and handler behavior are reviewed together. A payment call, notification and database update may need different recovery paths. Re-running a worker is not enough evidence that an external action happened only once. ## An invoice export recovers from a remote timeout Illustrative acceptance scenario: a worker sends an invoice to another system and times out before receiving confirmation. The scope changes the existing PHP application’s export worker and business state while retaining the established external API contract. The workflow records the uncertainty, applies the agreed deduplication or reconciliation rule and exposes unresolved work to an operator. The test also exercises invalid input and a permission failure. We define the external system assumptions first. This is an acceptance example, not a claim about a completed customer project. ## Upgrade dependencies around a verified business path The output includes source changes, relevant regression tests, compatibility findings and release instructions. We review deprecations and third-party constraints before selecting the upgrade sequence, with explicit handling for schema changes and worker restarts. A whole-system replacement remains [Legacy Modernization](/services/legacy-modernization/). Connections whose core purpose is exchanging records between existing tools belong to [API Integration](/services/api-integration/). ## Questions before you start ### Do we have to adopt Symfony? No. The current application and the intended change determine the approach. We can improve a bounded PHP workflow without introducing a framework that your team then has to maintain. ### Can you extend the application while preparing an upgrade? Yes, when the compatibility and release plan supports it. We separate the feature from unrelated cleanup and agree the regression checks for both the current and target environment. ### Does this page cover WordPress and every PHP CMS? No blanket CMS or plugin capability is implied. Describe the actual product and extension stack first; a publishing-site engagement belongs with Website Development. ### Will moving work to a queue make it reliable? A queue changes when work runs; it does not settle duplicate effects, missing permissions or external failures. We agree those rules and test the recovery paths as part of the job scope. ## Choose your next step - [Assess an inherited application](/services/software-takeover/) - [Choose the wider modernization strategy](/services/legacy-modernization/) - [Define a cross-system integration](/services/api-integration/) ## Structured Data ```json { "@context": "https://schema.org", "@graph": [ { "@id": "https://wavect.io/#organization", "@type": [ "Organization", "ProfessionalService", "LocalBusiness" ], "employee": [ { "@id": "https://wavect.io/team/kevin-riedl/#person", "@type": "Person", "jobTitle": "Managing Director", "name": "Kevin Riedl", "url": "https://wavect.io/team/kevin-riedl/", "worksFor": { "@id": "https://wavect.io/#organization", "@type": [ "Organization", "ProfessionalService", "LocalBusiness" ] } }, { "@id": "https://wavect.io/team/christof-jori/#person", "@type": "Person", "jobTitle": "Managing Director", "name": "Christof Jori", "url": "https://wavect.io/team/christof-jori/", "worksFor": { "@id": "https://wavect.io/#organization", "@type": [ "Organization", "ProfessionalService", "LocalBusiness" ] } } ], "founder": [ { "@id": "https://wavect.io/team/kevin-riedl/#person", "@type": "Person", "jobTitle": "Managing Director", "name": "Kevin Riedl", "url": "https://wavect.io/team/kevin-riedl/", "worksFor": { "@id": "https://wavect.io/#organization", "@type": [ "Organization", "ProfessionalService", "LocalBusiness" ] } }, { "@id": "https://wavect.io/team/christof-jori/#person", "@type": "Person", "jobTitle": "Managing Director", "name": "Christof Jori", "url": "https://wavect.io/team/christof-jori/", "worksFor": { "@id": "https://wavect.io/#organization", "@type": [ "Organization", "ProfessionalService", "LocalBusiness" ] } } ], "legalRepresentative": [ { "@id": "https://wavect.io/team/kevin-riedl/#person", "@type": "Person", "jobTitle": "Managing Director", "name": "Kevin Riedl", "url": "https://wavect.io/team/kevin-riedl/", "worksFor": { "@id": "https://wavect.io/#organization", "@type": [ "Organization", "ProfessionalService", "LocalBusiness" ] } }, { "@id": "https://wavect.io/team/christof-jori/#person", "@type": "Person", "jobTitle": "Managing Director", "name": "Christof Jori", "url": "https://wavect.io/team/christof-jori/", "worksFor": { "@id": "https://wavect.io/#organization", "@type": [ "Organization", "ProfessionalService", "LocalBusiness" ] } } ], "name": "Wavect GmbH", "subjectOf": { "@id": "https://wavect.io/verified-claims.json#dataset", "@type": "Dataset", "creator": { "@id": "https://wavect.io/#organization", "@type": [ "Organization", "ProfessionalService", "LocalBusiness" ] }, "description": "A machine-readable registry of quantitative and qualitative claims published by Wavect, with review dates, localized page appearances and public third-party citations where available.", "inLanguage": "en", "isAccessibleForFree": true, "license": "https://creativecommons.org/licenses/by/4.0/", "name": "Wavect verified publication claims", "url": "https://wavect.io/verified-claims.json" }, "url": "https://wavect.io/" }, { "@id": "https://wavect.io/team/kevin-riedl/#person", "@type": "Person", "jobTitle": "Managing Director", "name": "Kevin Riedl", "sameAs": [ "https://www.wikidata.org/wiki/Q139796365", "https://www.linkedin.com/in/wsdt", "https://github.com/wsdt" ], "url": "https://wavect.io/team/kevin-riedl/", "worksFor": { "@id": "https://wavect.io/#organization", "@type": [ "Organization", "ProfessionalService", "LocalBusiness" ] } }, { "@id": "https://wavect.io/team/christof-jori/#person", "@type": "Person", "jobTitle": "Managing Director", "name": "Christof Jori", "sameAs": [ "https://www.wikidata.org/wiki/Q139796367", "https://www.linkedin.com/in/jocr77/", "https://github.com/jo-chris" ], "url": "https://wavect.io/team/christof-jori/", "worksFor": { "@id": "https://wavect.io/#organization", "@type": [ "Organization", "ProfessionalService", "LocalBusiness" ] } }, { "@id": "https://wavect.io/#website", "@type": "WebSite", "inLanguage": [ "en", "de", "es", "zh" ], "name": "Wavect", "potentialAction": { "@type": "SearchAction", "query-input": "required name=search_term_string", "target": { "@type": "EntryPoint", "urlTemplate": "https://wavect.io/search/?q={search_term_string}" } }, "publisher": { "@id": "https://wavect.io/#organization", "@type": [ "Organization", "ProfessionalService", "LocalBusiness" ] }, "url": "https://wavect.io/" } ] } ``` ```json { "@context": "https://schema.org", "@graph": [ { "@id": "https://wavect.io/services/php-symfony-development/#service", "@type": "Service", "areaServed": [ { "@type": "Country", "name": "Austria" }, { "@type": "Place", "name": "Worldwide" } ], "category": "Languages & Frameworks", "dateModified": "2026-10-31", "description": "Improve existing PHP and Symfony applications with scoped feature work, dependency upgrades, reliable job handling and regression checks.
