Extend ArrayObject class

> The ArrayObject class is only rarely used at the moment due to a lack > for almost all array_* functions beside the sort functions. > > Currently implemented by ArrayObject: > https://www.php.net/manual/en/class.arrayobject.php > > Missing methods that would be most useful: > array_​chunk > array_​column > array_​diff_​assoc > array_​diff_​key > array_​diff_​uassoc > array_​diff_​ukey > array_​diff > array_​filter > array_​flip > array_​intersect_​assoc > array_​intersect_​key > array_​intersect_​uassoc > array_​intersect_​ukey > array_​intersect > array_​key_​first > array_​key_​last > array_​keys > array_​map > array_​merge > array_​pop > array_​push > array_​rand > array_​reduce > array_​replace_​recursive > array_​replace > array_​reverse > array_​search > array_​shift > array_​slice > array_​splice > array_​unique > array_​unshift > array_​values > shuffle > > > Furthermore, the already existing sort functions return VOID, which > isn't best for an object. Instead, returning the ArrayObject itself to > support a fluid interface would be much better, i.e.: > > $ao = new \ArrayObject([null, 'a' => 2, 'b' => 1]); > $ao->filter()->sort()->flip(); > > This change wouldn't break any existing code already using the ArrayObject. > > > It should be possible to extend from ArrayObject too and have access to > the internal array. Therefore, a new method would be required: > > protected getArrayRef() : array > > The method is similar to the existing getArrayCopy() method but returns > a reference to the internal array instead of a copy. Thus, classes > extending ArrayObject will be able to implement additional methods > efficiently without the need to create copies of the internal array first. > > -- > PHP Internals - PHP Runtime Development Mailing List > To unsubscribe, visit: http://www.php.net/unsub.ph > <http://www.php.net/unsub.php>
