Bug description:RecursiveIteratorIterator breaks after removing directories on disk
Description:
------------
I think this is similar to this bug -
https://bugs.php.net/bug.php?id=55468 except
I'm trying to delete
directories but not sure why this happens. If i remove the line
"rmdir(...)" then script completes successfully printing all empty
directory names to output. Once the line "rmdir(...)" is added back, it
breaks with the below stack trace.
I worked around this by saving all directory names, then removing
directories after the foreach loop completed.
Test script:
---------------
function deleteAllEmptyUserDirectories($path){
$iterator = new RecursiveDirectoryIterator($path);
$iterator->setFlags(RecursiveDirectoryIterator::SKIP_DOTS);
// Get directories only
$directories = new ParentIterator($iterator);
// Loop over directories and remove empty ones
foreach (new RecursiveIteratorIterator($directories,
RecursiveIteratorIterator::SELF_FIRST) as $dir) {
// Count the number of "children" from the main directory iterator
if (iterator_count($iterator->getChildren()) === 0) {
rmdir($dir->getPathname());
echo "[ DELETE ] " . $dir->getPathname() . "\n";
}
}
}
deleteAllEmptyUserDirectories("/home/me/somedir/content");
Expected result:
----------------
[ DELETE ] 0 | /home/me/somedir/content/test
[ DELETE ] 0 | /home/me/somedir/content/test2
Actual result:
--------------
[ DELETE ] 0 | /home/me/somedir/content/test
PHP Fatal error: Uncaught exception 'UnexpectedValueException' with
message
