Extend legacy

PHP Secondary Development

Secondary work fails when you dig without knowing where the mines are.

Add features, fix defects and limited refactors on existing PHP systems.

Handover-ready code Clear layout, naming and config so your team can continue.
Frameworks for fit Laravel/ThinkPHP chosen by scenario—not fashion.
Data layer included Schema and query paths designed with the app.

Secondary risks

These usually show up before a project starts—or right after a rushed launch.

01

No tests—one change breaks many—teams then argue across ownership lines.

02

Deps won't install; envs unreproducible—it often surfaces only after production impact.

03

No DB migrations—iteration and local integration slow down.

04

Author gone—knowledge gap—users feel it as inconsistent data or UX.

Health-check-driven increments

Reproduce env and critical paths; add minimal tests or manual checklists; localize changes; fill doc gaps. Health-check first: deps, entrypoints, DB and deploy. Risk-ordered changes—avoid big-bang rewrites unless required.
