returns information about

: either an associative array or a string, depending on . pathinfo``path``flags

Opmerking: > For information on retrieving the current path info, read the section on . predefined reserved variables

Opmerking: > operates naively on the input string, and is not aware of the actual filesystem, or path components such as "". pathinfo``..

Opmerking: > On Windows systems only, the character will be interpreted as a directory separator. On other systems it will be treated like any other character. \

Let op: > is locale aware, so for it to parse a path containing multibyte characters correctly, the matching locale must be set using the function. pathinfo``setlocale

pathThe path to be parsed.

flags If present, specifies a specific element to be returned; one of , , or . PATHINFO_DIRNAME``PATHINFO_BASENAME``PATHINFO_EXTENSION``PATHINFO_FILENAME

If is not specified, returns all available elements. flags

If the parameter is not passed, an associative containing the following elements is returned: , , (if any), and . flags``array``dirname``basename``extension``filename

Opmerking: > If the has more than one extension, returns only the last one and only strips the last one. (see first example below). path``PATHINFO_EXTENSION``PATHINFO_FILENAME

Opmerking: > If the does not have an extension, no element will be returned (see second example below). path``extension

Opmerking: > If the of the starts with a dot, the following characters are interpreted as , and the is empty (see third example below). basename``path``extension``filename

If is present, returns a containing the requested element. flags``string

Voorbeeld: Example

<?php
$path_parts = pathinfo('/www/htdocs/inc/lib.inc.php');

echo $path_parts['dirname'], "\n";
echo $path_parts['basename'], "\n";
echo $path_parts['extension'], "\n";
echo $path_parts['filename'], "\n";
?>

/www/htdocs/inc
lib.inc.php
php
lib.inc

Voorbeeld: example showing difference between null and no extension

<?php
$path_parts = pathinfo('/path/emptyextension.');
var_dump($path_parts['extension']);

$path_parts = pathinfo('/path/noextension');
var_dump($path_parts['extension']);
?>

string(0) ""

Notice: Undefined index: extension in test.php on line 6
NULL

Voorbeeld: example for a dot-file

<?php
print_r(pathinfo('/some/path/.test'));
?>

Array
(
    [dirname] => /some/path
    [basename] => .test
    [extension] => test
    [filename] =>
)

Voorbeeld: example with array dereferencing

 The  parameter is not a bitmask. Only a single value
 may be provided.  To select only a limited set of parsed values, use array
 destructuring like so:
`flags`

<?php
['basename' => $basename, 'dirname' => $dirname] = pathinfo('/www/htdocs/inc/lib.inc.php');

var_dump($basename, $dirname);
?>

string(11) "lib.inc.php"
string(15) "/www/htdocs/inc"
