Reflector Overview

Backend Connecting Reflector

These reflectors connect to a real database, infer types based on result-set/schema metadata and are able to detect errors within a given sql query. It is not mandatory to use the same database driver for phpstan-dba, as you use within your application code.

Reflector	Key Features
MysqliQueryReflector	- limited to mysql/mariadb databases - requires a active database connection - most feature complete reflector
PdoMysqlQueryReflector	- connects to a mysql/mariadb database - requires a active database connection
PdoPgSqlQueryReflector	- connects to a PGSQL database - requires a active database connection

Utility Reflectors

Utility reflectors will be used in combination with backend connecting reflectors to provide additional features.

Reflector	Key Features
ReplayAndRecordingQueryReflector	- wraps a backend connecting reflector, caches the reflected information into a local file and utilizes the cached information - will re-validate the cached information - will update local cache file information, even on external changes - will reduce database interactions to a minimum, but still requires a active database connection
RecordingQueryReflector	- wraps a backend connecting reflector and caches the reflected information into a local file - requires a active database connection
ReplayQueryReflector	- utilizes the cached information of a *RecordingQueryReflector - will not validate the cached information, therefore might return stale results - does not require a active database connection
ChainedReflector	- chain several backend connecting reflectors, so applications which use multiple database connections can be analyzed
