Doc->Req #76024 [Fbk->Opn]: Elements disappear After Interaction with SplHeap

Edit report at https://bugs.php.net/bug.php?id=76024&edit=1 ID: 76024 User updated by: mt at mfmello dot com Reported by: mt at mfmello dot com Summary: Elements disappear After Interaction with SplHeap -Status: Feedback +Status: Open -Type: Documentation Problem +Type: Feature/Change Request Package: SPL related Operating System: Linux Mint 18.1 64bits PHP Version: 7.0.27 Block user comment: N Private report: N New Comment: Yes, I made the change. This issue could be extended to any looping interaction in the spline data structures that come by default by removing the current element after advancing to the next key in the array. So the community would have more control over their data. Original (pt-br): Sim, fiz a alteração. Essa questão poderia ser estendida para toda interação em loop nas estruturas de dados da biblioteca Spl que venham por padrão removendo o elemento atual após avançar para a próxima chave da matriz. Assim a comunidade teria mais poder de controle sobre seus dados.

Using the SplHeap::next method does not deduce that the object will be removed, but rather that the array will simply be advanced one position forward. Even if this action were expected for the programmers it would be very useful to be able to configure this as it does in the SplDoublyLinkedList that we can change the mode of the Interator.

Mesmo que essa ação fosse esperada para os programadores seria muito útil poder configurar isso assim como ocorre no SplDoublyLinkedList que podemos alterar o modo do interador. ------------------------------------------------------------------------ [2018-02-28 12:50:51] salathe@php.net SplHeap::next() already documents that calling this method (which happens implicitly using foreach) will delete the top node of the heap. -- http://php.net/manual/en/splheap.next.php ------------------------------------------------------------------------ [2018-02-28 10:18:30] cmb@php.net This behavior is by design[1].
