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

$path_parts = pathinfo(__FILE__);
print_r($path_parts);
/*
Array
(
    [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.
