Bug #78799 [Opn->Nab]: Calling iterator_count() is killing the validity of RecursiveDirectoryIterator

Edit report at https://bugs.php.net/bug.php?id=78799&edit=1 ID: 78799 Updated by: requinix@php.net Reported by: k-gun at mail dot com Summary: Calling iterator_count() is killing the validity of RecursiveDirectoryIterator -Status: Open +Status: Not a bug Type: Bug Package: SPL related Operating System: Ubuntu PHP Version: 7.4.0RC4 Block user comment: N Private report: N New Comment: https://www.php.net/manual/en/function.iterator-count.php > iterator_count() is not guaranteed to retain the current position of the iterator. The only way to count how many items there are in an iterator is to run it to the end.

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
