Features

• Static Analysis Engines - Examines files and directories to identify bugs and type errors without executing the code, returning a status code based on findings.
• Static Analysis - Identifies potential bugs, type mismatches, and logic errors by scanning source code without execution.

• Framework Integration - Recognizes and validates framework-specific patterns, dependency injection, and dynamic class behaviors in PHP projects.
• PHP Type Checkers - Enforces strict type safety and validates complex data structures using advanced type inference and annotations.
• Type Inference Engines - Calculates and propagates variable types through the codebase by evaluating expressions, assertions, and annotations.
• Static Code Analysis Tools - Identifies bugs, type mismatches, and logic errors by scanning source code without executing the application.
• Static Type Inference Engines - The static analysis tool infers variable, return, or expression types dynamically based on arguments, context, or custom logic to improve analysis accuracy.
• PHP Development Tools - Provides a framework-agnostic platform for maintaining code quality through incremental analysis and custom validation rules.
• Baseline Management - Creates configuration files containing existing errors to ignore them in future runs, allowing for incremental adoption of stricter rules.
• Custom Rule Development - Implements bespoke validation logic and architectural constraints to enforce project-specific coding standards.
• Technical Debt Management - Tracks and suppresses existing code issues through baselines to allow for the incremental adoption of stricter quality standards.
• Static Analysis Rules - The static analysis tool configures specific methods or functions as execution-terminating to prevent false reports of undefined variables in subsequent code paths.
• Static Code Analysis - Scans source code to identify potential runtime errors, dead code, and violations of project-specific coding standards.
• Type Inference Refinement - Analyzes conditional logic and assertions to narrow down variable types for more precise error detection.
• Static Analysis Modeling - The static analysis tool exposes dynamically generated properties and methods to the static analyzer to ensure correct type checking for magic behavior.

• Static Analysis Extensions - Integrates framework-specific rules and plugins to extend the core analysis engine's capabilities.
• Static Analysis - Detects errors without executing the code.
• Static Analysis Rules - Customizes the strictness of code checks by defining rule levels, enabling preview features, or creating bespoke rulesets.
• Analysis Suppression Mechanisms - Excludes particular code issues from the reporting process by referencing their unique identifiers within configuration files or inline source code comments.
• State Tracking - The static analysis tool updates the inferred type of an object instance after specific methods are called to support mutable generic objects.
• Local Variable - Refines inferred variable types within function bodies using assertions and inline annotations.
• Static Analysis Declarations - The static analysis tool declares properties and methods that are handled dynamically via magic methods to ensure static analysis recognizes them as valid members.
• Advanced Type Annotation Support - Provides complex type information to the analysis engine using prefixed tags while maintaining IDE compatibility.
• Custom Validation Rules - Executes modular rules against the code tree to identify violations and enforce project-specific coding standards.
• Object Shape Validation - Enforces specific property requirements on objects to ensure they contain the expected data fields and types.
• Array Shape Validation - Defines strict structures for arrays by specifying required keys, optional keys, and value types for each element.
• Strictness Levels - Adjusts the depth of static code analysis by selecting from multiple cumulative levels to incrementally enforce type safety.
• Architectural Constraints - Enforces architectural requirements by mandating specific class inheritance or interface implementation patterns.
• Control Flow Analysis - The static analysis tool marks functions that never return, such as those throwing exceptions or terminating the script, to help the analyzer track code paths.
• Regression Analysis Tools - Performs binary search across tool versions to identify the specific commit that introduced a regression in analysis behavior.
• Type Narrowing Assertion - Informs the analysis engine about conditional type changes that occur after specific function or method calls.
• Custom Type Constraint Enforcement - Enforces specific type requirements across function boundaries using documentation annotations.
• Symbol Type Overriding - Refines inferred types for variables, properties, and methods when native typehints are insufficient.
• Custom Analysis Rules - Implements bespoke validation logic using abstract syntax trees and type inference to enforce project-specific coding standards.
• Extensible Plugin Architectures - Allows developers to register custom logic and plugins that hook into the analysis pipeline to support framework-specific patterns.
• Generic Type Definitions - The static analysis tool uses type parameters to create flexible, reusable components that maintain strict type safety across different data inputs.
• Purity Annotations - The static analysis tool labels functions as pure or impure to control how the analysis engine handles repeated calls and global state dependencies.
• Type-Aware Inspection Engines - Performs deep code inspection by accessing compiler type information to assist in debugging complex type resolution issues.
• Analysis Result Dashboards - Launches an interactive web interface to browse and manage identified code errors and ignored issues.
• Dynamic Behavior Validation - The static analysis tool interprets and validates magic properties and methods created via dynamic class magic to ensure code correctness despite unconventional implementation patterns.
• Analysis Result Caches - Stores intermediate results of processed files to skip redundant computations and accelerate subsequent analysis runs.
• Codebase Data Aggregation - Collects and processes information across multiple files to support complex analysis rules that require global context.
• Custom Type Assertion Mapping - Maps complex validation logic or external assertion libraries to type-narrowing rules for the analysis engine.
• Analysis Result Exporters - Exports findings into various machine-readable or human-friendly formats including JSON, XML, and CI-specific schemas.
• Usage Policy Enforcement - Prevents unauthorized access to symbols by marking code as deprecated, internal, or restricted.
• Callable Behavior Descriptions - Specifies the execution timing and scope of closure arguments to ensure accurate analysis of callbacks.
• External Type Definition Overrides - Corrects imprecise type information in third-party code using custom documentation annotations.
• Type Aliasing - Creates reusable shorthand names for complex type definitions to simplify documentation and improve consistency.
• Collection Type Refinement - Supplements native typehints with detailed information about array contents, key types, and object instances.
• Function Signature Enforcement - Enforces exact parameter and return types for callback functions to ensure they receive the correct data structures.
• Conditional Types - The static analysis tool infers function return types dynamically based on the provided input arguments or logical conditions within the code.
