Yesterday the PHP team released PHP 7.3.0 for general availability (GA) and marked the third feature update to PHP 7. You can download the latest version from the official PHP downloads page. You can also get all the nitty-gritty details about PHP 7.3 by reading the PHP 7 changelog on the official site.

While today marks the day of the stable release, you will have to wait a bit longer for the migration guide, which should be available shortly.

If you haven’t read much on PHP 7.3 yet, here are the highlight features coming to PHP 7.3:

Trailing Commas in function calls
JSON_THROW_ON_ERROR flag for json_encode() and json_decode()
Flexible Heredoc and Nowdoc syntax
An is_countable() function
list() reference assignment
Besides the flagship PHP 7.3 announcement, December 6th included five total PHP releases:
