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.php
