![]() ![]() So it goes for the paths in the computer world: given the absolute address, you can always get to the place, no matter from where you started. However, given the relative directions, like "keep three blocks this way and then and turn to the right" would work from the current location only, otherwise sending you astray. Given the absolute address, a postal one, like "7119 W Sunset Blvd West Hollywood, CA 90046" you can find the location from anywhere. It's exactly the same as with the real life directions. If the path is built starting from the current location, it is called relative (which makes sense, as it is relative to our present position).If the path is built starting from the system root, it is called absolute. ![]() The difference between absolute and relative paths The difference between the root of the web server and the filesystem root.The difference between absolute and relative paths.However, to sort these things out all you need is to grasp just two simple concepts: PHP users confuse these matters badly at first, doing things like being unable to locate an existing file, confusing hyperlinks with files, including local files via HTTP and such. So this dualism is the root of many problems. And your PHP script, while reading data files or including other scripts, is working with such real files that exist on the physical medium. ![]() All it needs to know is an address.įor the site developer, on the other hand, their site is a certain program running on a particular server, on the very real computer with HDD, files and directories. Your browser cannot know that, and don't need to. There could be or could be not a real file with such a name, but it doesn't matter. In the address like, file.html is not a file. I know, it's hard to believe at first, but it's a fact. Your site exists in two realms at once: the real and the virtual one.įor the site visitors it's entirely a virtual server, which in many ways is different from a real one. The difference between absolute and relative paths.In addition, relationships such as PeerOf and CanAlsoBe are defined to show similar weaknesses that the user may want to explore.Relative and absolute paths, in the file system and on the web server. These relationships are defined as ChildOf, ParentOf, MemberOf and give insight to similar items that may exist at higher and lower levels of abstraction. This table shows the weaknesses and high level categories that are related to this weakness. Improper Control of Generation of Code ('Code Injection') Variant level weaknesses typically describe issues in terms of 3 to 5 of the following dimensions: behavior, property, technology, language, and resource. That is linked to a certain type of product, typically involving a specific language or technology. Inclusion of Functionality from Untrusted Control Sphere Base level weaknesses typically describe issues in terms of 2 or 3 of the following dimensions: behavior, property, technology, language, and resource. That is still mostly independent of a resource or technology, but with sufficient details to provide specific methods for detection and prevention. Use of Incorrectly-Resolved Name or Reference Class level weaknesses typically describe issues in terms of 1 or 2 of the following dimensions: behavior, property, and resource. More specific than a Pillar Weakness, but more general than a Base Weakness. ![]() Class - a weakness that is described in a very abstract fashion, typically independent of any specific language or technology. ![]()
