Edit report at https://bugs.php.net/bug.php?id=79404&edit=1 ID: 79404 Updated by: nikic@php.net Reported by: vlad dot turchinskiy at yandex dot ru Summary: Referencing to SplFixedArray interrupts foreach loop Status: Closed Type: Bug Package: SPL related Operating System: all PHP Version: 5.4.0 - 7.4.4 Assigned To: cmb Block user comment: N Private report: N New Comment: (Correction: This is fixed in 8.0.0, rather than 8.1.0.) Previous Comments: ------------------------------------------------------------------------ [2021-01-08 15:17:48] cmb@php.net The fix for this issue has been committed[1], and will be available as of PHP 8.1.0 for BC reasons.

It's a pretty dubious idea. Still, I may push it to GH for review and comments. ------------------------------------------------------------------------ [2020-04-10 14:31:39] requinix@php.net > Nikita, I don't understand how SplFixedArray could possibly support multiple > parallel get_iterator()s while still following the contract of the Iterator > interface. Could you explain what you mean? To make sure that all the Traversables returned by multiple calls to getIterator() won't conflict with each other. ------------------------------------------------------------------------ [2020-04-10 08:41:30] alexinbeijing at gmail dot com > I do think we should ensure that multiple parallel get_iterator()s are supported independently > of that.
