Re: [RFC] foreach_variable supporting T_LIST token

Hi: first of all, I am a guy whose english is poor, sorry for making you confuse. the feature request is here: https://bugs.php.net/bug.php?id=10203 and I think this can make php code more flexible, and more making sense. example: foreach (array( array(3, array(1, 2)), array(7, array(3, 4)), ) as list($sum, list($op1, $op2))) { printf("%d + %d = %d\n", $op1, $op2, $sum); } output: 1 + 2 = 3 3 + 4 = 7 plz read the RFC for more details. thanks 2011/7/6 Stefan Neufeind <neufeind@php.net>: > Hi, > > On 07/06/2011 03:06 PM, Hannes Magnusson wrote: >> 2011/7/6 Xinchen Hui <laruence@gmail.com>: >>> >>>   T_LIST is not allowed to used with foreach before. >>> >>>   and then there comes a freature request:  #10203  allow >>> foreach($array as list($a,$b) >> >> Ironically enough you managed to miss the last closing ), enforcing >> the point of this not being a natural syntax. >> >> Furthermore, without reading the RFC, is this the same as >> foreach($array as $a => $b) {} > > No, there $a would be the key.
