Php obtains the file name and extension.

1. basename ()-returned path file name

See the following php code:

 "; // If suffix is selected, the echo basename ($ path,". php ") extension is ignored.?>

Running result:

Index. php

Index

2. dirname ()-returns the file path of the current script!

Php code:

Running result:

F: \ web \ zend \ exercise

3. pathinfo () returns an associated array containing path information.

It includes the following array units: path name dirname, file name basename, and extension name extension.

See the following simple code demonstration:

 "; Echo" File name: $ pathinfo [basename]
"; Echo" extension: $ pathinfo [extension] ";?>

Running result:

Directory name:/usr/www/html

File name: index. php

Extension: php

4. realpath -- returns the normalized absolute path name.

The php code is as follows:

Note the following tips: file path operators in different paths may be different. in windows, "/" and "\" can be used "\",

Only "/" can be used in linux, so we recommend that you use "/" during development, such as the file path above!
