Path Information

Split filename infos: pathinfo()

The function pathinfo() is useful when you have a filename and you want to obtain:

  • dirname: the directory
  • basename: the filename with extension
  • extension: the extension
  • filename: the filename without extension
$path_parts = pathinfo(__FILE__);
[dirname] => /Users/user/project/BOOKS/50-drops-of-php/examples
[basename] => 503_fil_pathinfo.php
[extension] => php
[filename] => 503_fil_pathinfo

The input is a string with the filename, the result is an associative array with dirname, basename, extension, filename attributes.
