Php dirname, basename, pathinfo parsing directory path

A string containing a full path pointing to a file is provided. This function returns the basic file name. If the file name ends with suffix, this part will also be removed.

In Windows, both slash (/) and backslash () can be used as path separators. It is a slash (/) in other environments (/).

The code is as follows:

<? Php

$ Path = Web page creation tutorial http://www.111cn.net, keep this tag "/home/httpd/html/index. php ";
