A PHP directory is a structure used to catalog and keep our files. It's a part of an organizing system that lets us keep track of our projects and code files more easily.
PHP has a bunch of inbuilt functions that let us quickly fetch information about particular PHP files in the directory. Additionally, it is possible to retrieve data about a whole specific PHP directory. We can easily make PHP list files in directory, open specified handles, and perform other tasks.
