• Server-Side Request Parameter Accessors - Provides access to server-side request parameters as a core part of the PSR-7 server request interface.
• Body Streaming - Models message bodies as streamable objects for efficient processing of large payloads.
• Stream Interfaces - Provides the PSR-7 StreamInterface for efficient body handling without full memory loading.
• PHP Superglobal Abstractions - Abstracts PHP superglobals into structured request objects as a core part of the PSR-7 server request interface.

• Safe Uploaded File Movers - Provides safe file movement for uploaded files as a feature of the PSR-7 uploaded file interface.
• Uploaded File Tree Normalizers - Normalizes the PHP $_FILES array into a consistent tree structure as a feature of the PSR-7 uploaded file interface.
• HTTP Header Validations - Enforces standardized naming and value constraints on HTTP headers to prevent injection attacks.
• Header Name and Value Validations - Rejects malformed header names and values to prevent CRLF injection and parsing attacks.
• Request Target Overrides - Allows overriding the default request target to support specialized HTTP request forms.
• Request-Target Form Handlers - Supports all four forms of the HTTP request-target as a feature of the PSR-7 request interface.
• Request Target Representations - Defines the four standard forms of HTTP request targets for message representation.
