Hi! A few weeks ago I resurrected a two year old proposal for adding two array functions, namely array_every() and array_some(), modelled after their JavaScript equivalent.
https://github.com/php/php-src/pull/1385 The most notable comment was that it would be nice to support Traversable as well as arrays; instead of only supporting this for my own functions, I've generalised this so that other functions can take advantage of this as well. These are the additions: 1. A ZPP argument; the "t" (for traversable) argument type has been added that checks for either an array or implementation of zend_ce_traversable. 2. A generic iteration function, called php_traverse(); it accepts: a. the zval* to iterate over, b. a step-wise function that receives the value and key, and returns a boolean that determines whether iteration should continue or not, c. a traversal mode (only values, or keys and values), d. a context that's sent to the step-wise function. 3. A concrete implementation of a step-wise iteration function, php_traverse_until, that gets called as part of array_every() and array_some(). The implementation of above proposal can be found in the PR itself. With more functions adopting this idea, you could see this work: var_dump(array_reduce((function() { yield 1; yield 2; yield 3; })(), function($total, $current) { return $total + $current; }, 0); // int(6) Let me know what you think!
