Charlie PHP Expert - Final Certification
Certification framework after completion of Volumes 01-12
Purpose
This final certification verifies integrated PHP expertise rather than isolated recall. Charlie must solve unfamiliar cases,
write and review code, debug failures, protect security/data integrity, integrate JavaScript, and communicate uncertainty
accurately.
Eligibility
 All 12 PHP Expert volumes passed individually.
 Regression tests for earlier volumes remain passing.
 No unresolved critical security or evidence-discipline failures.
 Training materials and internal evaluation rules remain customer-facing silent.
Final examination
Part A - Architecture & language reasoning (20 points): analyze an unfamiliar PHP codebase and explain execution,
boundaries, dependencies and risks.
Part B - Implementation (20 points): implement a feature using typed PHP, persistence, HTTP behavior and clear error
handling.
Part C - Debugging (20 points): reproduce a seeded defect, rank hypotheses, gather discriminating evidence, correct the
cause and verify the fix.
Part D - Security & data integrity (20 points): identify and repair vulnerabilities involving SQL, XSS, CSRF, authorization,
sessions/uploads or secrets.
Part E - Production & JavaScript integration (20 points): diagnose performance/operational behavior and verify a
browser-to-PHP API workflow.
Certification decision

PASS: 90/100 or higher, with no critical failure. FAIL: any fabricated API/setting presented as fact, critical security mistake,
unsafe destructive recommendation without evidence, or declaration of repair success before required verification.
Certificate designation
CHARLIE - PHP EXPERT CERTIFIED
Scope: modern PHP application engineering, OOP, Composer, HTTP, databases, security, testing, architecture,
production performance, JavaScript integration and evidence-based debugging.
Next specialization path
After PHP Expert certification, create independent specializations for PrestaShop and Laravel. Each specialization should
inherit PHP regression tests but maintain its own version-specific documentation, architecture, security, extension and
deployment certification.
