Why does php7 performance improve?

Summary of reasons for PHP7 performance improvement:

1. The structure that stores variables becomes smaller, and try to make the members of the structure share memory space. Reduce references, thus reducing memory usage and improving variable operation speed.

2. Changes to the string structure. The string information and data itself were originally stored in two independent memory blocks. PHP7 tries to store them in the same memory block, which improves the CPU cache hit rate.

3. Changes in the array structure. Array elements and hash mapping tables will be stored in multiple memory blocks in php5. php7 tries to allocate them in the same block of memory, reducing memory usage and improving cpu cache. Hit rate.

4. The function calling mechanism has been improved. By optimizing the parameter transfer link, some instruction operations have been reduced and execution efficiency has been improved.
