A PHP request begins with server-populated inputs and ends when its response and request process finish. These lessons track a permit review from typed input through session authorization, a database transaction, and private document intake. The examples use PHP directly so framework abstractions can be evaluated against the same boundaries.
Topics in this track
- PHP Superglobal Input and Output Trust — Convert request globals into typed commands and escape only at the output context.
- PHP Session Rotation, Locking, and Logout — Treat the session cookie as an identity pointer with explicit rotation, release, and revocation.
- PHP PDO Transactions, Replay, and Query Identity — Bind query values and keep a replay key, version check, and outbox intent in one transaction.
- PHP Upload Tempfiles, Private Storage, and Lifecycle — Validate the upload error and actual bytes before moving a temporary file into private ownership.
Prerequisite paths
Sessions and CSRF: keep identity on the server; Laravel Policy, Query, and Queue Boundaries; Safe File Upload Pipeline.
