Path and operation of PHP files

Relative path

Path relative to the directory where the current file resides

Current directory:.

Top level directory:.

Path delimiter:/

Absolute path

The root of the operating system or the location of the site's document roots Score
If the path is executed in the server (through a PHP file handler), then "root" refers to the root of the operating system
If the program is a downloaded client, and then access the files on the server, only through Apache access, "root" also refers to the document root directory

Functions related to file operations

Create a file Touch ("file name")
Delete File unlink ("File path");

Cut/Rename File rename ("Original path", "New Path")

Copy the file copy ("Current", "target");

The above describes the PHP file path and operation, including the aspects of the content, I hope the PHP tutorial interested in a friend helpful.
