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
