PHP7 is most notable because it doubles the speed and halved the memory, greatly improving the performance.
I learned LAMP technology from PHP5.
Note:
For Linux: 1991
Apache: 1995
MySQL: 1995.
PHP 1995
LAMP members are both post-90s and post-90s.

Why not go to PHP.net?

All the answers can be found in the appendix of the PHP official manual.
