Forbidden Namespaces Rule

Enforces that certain namespaces cannot be declared in your codebase. This rule checks the namespace keyword and prevents the declaration of namespaces matching specified regex patterns, helping to enforce architectural constraints.

        arguments:
            forbiddenNamespaces: [
                '/^App\\Legacy\\.*/',
                '/^App\\Deprecated\\.*/'
            ]
        tags:
            - phpstan.rules.rule

Parameters

• forbiddenNamespaces: Array of regex patterns matching namespaces that are not allowed to be declared.
