Are there Russian resources for learning PHP 7?

Question

PHP

I would really like to know if there are resources or documentation in Russian for PHP 7. So far I have only found it in English. Perhaps someone has experience using it? If yes, is it really a good release? Are there significant performance differences?

Answer 1

Learning PHP7 is no different from PHP5. More precisely, learning PHP7, after PHP5 will be to read "what's new".
The release is successful. There is a performance boost. Significant.

Answer 2

Exclusively PHP7? PHP7 is not very different from PHP5.6 for 95% of the tasks. Concerning a resource - did not meet. The release is very successful. There are enough articles on Habrahabr describing the advantage of the 7th version.
Personally, I did a simple test with 100,000,000 empty for loops, the result is:
--PHP 5.2: 5.30796 seconds
--PHP 5.3: 6.42107 seconds
--PHP 5.4: 3.05346 seconds
--PHP 5.5: 3.21097 seconds
--PHP 5.6: 3.31220 seconds
--PHP 7.0: 1.59607 seconds
Also the speed depends on the number of connected libraries. So connecting xdebug increases the required execution time several times (usually 2-3 times).
