PHP 4.0 Bug #6002 Updated: array_diff / array_intersect returning wrong elements

ID: 6002 Updated by: waldschrott Reported By: hpdl@theexchangeproject.org Status: Analyzed Bug Type: Feature/Change Request Assigned To: Comments: both: array_diff() && array_intersect: not really sure whether it´s a documentation issue (unexpected behaviour) or a bug, if you try "var_dump($result);" you´ll receive array(2) { [1]=> string(5) "page2" [2]=> string(5) "page3" } that´s fine, it has preserved the keys too! (perhaps a nice feature) I think it´s like with comparing arrays with == and ===, I´d vote for a FLAG on array_diff() (and array_intersect()), indicating if it should perform an ordered _diff (_intersect)(preserving keys, usually equal or fewer matches then unordered _diff) or unordered _diff (_intersect)(flatten(resuling array begins at index 0), finds all similarities) Resumé: I think it should be transformed into a Feature/Request bug and if not changed, it should be documented.
