Previous Comments: ------------------------------------------------------------------------ [2019-11-09 01:46:22] k-gun at mail dot com Description: ------------ Hi, Calling iterator_count() is affecting RecursiveDirectoryIterator::valid() and RecursiveDirectoryIterator::valid() is returning false after iterator_count() call. I am not sure that is a bug or just a behavior of PHP, but simply looks weird invalidating it without any iteration act such as while or foreach. Test script: --------------- $iter = new RecursiveDirectoryIterator("/tmp/", RecursiveDirectoryIterator::SKIP_DOTS); var_dump($iter->valid()); var_dump(iterator_count($iter)); var_dump($iter->valid()); Expected result: ---------------- bool(true) int(24) bool(true) Actual result: -------------- bool(true) int(24) bool(false) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=78799&edit=1
