From the birth of PHP to the current PHP 7, which version of PHP has undergone the changes? What are the important new features of each big version change?

Official documents are:
http://php.net/manual/zh/history.php
The most noticeable part of the PHP7 is the doubling of speed, half of memory, and a dramatic increase in performance.
I began to learn lamp technology from PHP5.
Note that:
linux:1991
apache:1995
mysql:1995
php:1995
Lamp members are the same, I am also a.

Why not go to see php.net?

The appendix to the official PHP manual will tell you all the answers.
