: A security filter might only check the last extension ( .jpeg ) and assume the file is a safe image. However, if the web server (like Apache) is misconfigured, it might execute the file as a PHP script because it sees the .php part.
In standard web development, a PHP file can act as an image. By using the PHP GD Library , developers can create, resize, or watermark images on the fly.
Adaptive and formative, InQuizitive addresses the two primary challenges that most students face: vocabulary building and building a conceptual understanding of immunology.
88 new figures throughout the text highlight new research. Many of these figures are made assignable through InQuizitive.
For the first time, every copy of Janeway’s Immunobiology will include access to the full ebook of Case Studies in Immunology (Notorangelo and Geha).
