realpath

Definition and usage

realpath() function returns an absolute path.

This function deletes all symbolic connections (such as '/./', '/../' and redundant '/') and returns the absolute pathname.

If it fails, return false. For example, if the file does not exist.

Example

 <?php
echo realpath ( "test.txt" ) ;
?>

Output:

 C:\Inetpub\testweb\test.txt

grammar

 readlink ( linkpath )

illustrate

On BSD systems, if linkpaths are just not present, PHP does not return false like other systems.
