Worked on enhancing the developer experience for the microsoftgraph/msgraph-sdk-php repository by focusing on documentation improvements and sample reorganization. Leveraged PHP and Markdown to expand and clarify usage documentation, making integration with the Microsoft Graph PHP SDK more accessible for developers. Updated and reorganized sample files, including new examples for application, Drives, Groups, and SharePoint, while removing outdated materials to streamline guidance and reduce maintenance. Emphasized API integration and SDK usage best practices, ensuring documentation reflected the latest usage patterns. These efforts aimed to accelerate onboarding, reduce integration friction, and improve maintainability for developers working with the PHP SDK.
