Hi all, Remember my question about ??= operator?
Forgive my rookieness and let me introduce my first RFC here: https://wiki.php.net/rfc/null_coalesce_equal_operator <https://wiki.php.net/rfc/null_coalesce_equal_operator> Let me also include here the introduction I wrote: Combined assignment operators are around since 1970's, appearing first in the C language. Consider the following code $x = $x + 3 that has the ability to be shortened into $x += 3. Hence PHP is a web focused language, ?? operator is used to check something's existence like $username = $_GET['user'] ?? 'nobody'; However due to common variable names are much longer than $username the use of ?? self assignment, creates repeated code. $this->request->data['comments']['user_id'] = $this->request->data['comments']['user_id'] ?? ‘value’; It is also intuitive to use combined assignment operator null coalesce checking for self assignment. I am sure there would be some language mistakes, please also forgive me for them too. Currently I created a working implementation here: https://github.com/php/php-src/pull/1795 <https://github.com/php/php-src/pull/1795> you can see a terminal working with my implementation also here: http://imgur.com/zLlVFup <http://imgur.com/zLlVFup> I hope I managed to write a simple and understandable RFC. Thank you all for your efforts. Best Wishes, Midori Kocak Computer Scientist & Engineer / ZCPE http://www.mynameismidori.com <http://www.mynameismidori.com/>
