Benchmarking execution times of PHP from 7.1 to 7.4

Benchmarking execution time of PHP from 7.1 to 7.4

In this experiment, I tested the execution time of the script Zend\bench.php available in the PHP socurce code. I tested the latest PHP versions available, as follows:

  • PHP 7.1.32
  • PHP 7.2.22
  • PHP 7.3.9
  • PHP 7.4RC1

I executed the experiment using an Intel(R) Core(TM) i9-8950HK CPU @ 2.90GHz, with 32GB RAM, HD SSD running Linux Ubuntu 18.04.3 LTS.
