PHP Bug Type: SPL related
Bug description: RecursiveDirectoryIterator::current() always returns
SplFileInfo
Description:
------------
The return value for RecursiveDirectoryIterator::current() is _always_
SplFileInfo, which isn't as expected and is less useful than the behavior
in previous versions within the 5.2.x branch. At least one other programmer
has submitted this as a bug, as well (see #37530), however he was dismissed
with the standard RTFM boilerplate.
This is a flaw in the behavior of the class, IMO, however, since there's
no way to _disable_ the class from returning SplFileInfo. The SPL
documentation briefly refers to a flag that can be passed to __construct()
named "CURRENT_AS_FILEINFO", which would indicate to me that the default
behavior for the class is to return something _other_ than SplFileInfo for
current().
The docs seem to back that up, listing the variable behavior of current()
to alternate between getFilename() and getFileInfo(). However, the class
consistently returns SplFileInfo, regardless of the flags provided to the
constructor.
Reproduce code:
---------------
<?php
function testReturnTypeOfCurrent ( $Directory, $assertion )
{
$assertion = sprintf($assertion, '$Node');
echo 'Asserting: ' . $assertion, "\n";
foreach ( $Directory as $Node )
{
echo ( @assert($assertion) ?
'Assertion Passed!' : 'Assertion Failed!' ), "\n";
}
} // END testReturnTypeOfCurrent
testReturnTypeOfCurrent(
new RecursiveDirectoryIterator('/path/to/walk'),
'gettype(%s) == "string"'
);
testReturnTypeOfCurrent(
new RecursiveDirectoryIterator(
'/path/to/walk'
RecursiveDirectoryIterator::CURRENT_AS_FILE
),
'%s instanceof SplFileInfo'
);
Expected result:
----------------
Asserting: gettype($Node) == 'string'
Assertion Passed! x number of items in /path/to/walk
Asserting: $Node instanceof SplFileInfo
Assertion Passed! x number of items in /path/to/walk
Actual result:
--------------
Asserting: gettype($Node) == 'string'
Assertion Failed! x number of items in /path/to/walk
Asserting: $Node instanceof SplFileInfo
Assertion Passed! x number of items in /path/to/walk
