Comment from Tadashi Yoshimasa, Representative of Engineer Certification Corporation for PHP

PHP 7 is the first major version release in almost 10 years, and it improves and advances a lot of features. PHP 7 can now be used with the Ultrafast WordPress Execution Environment KUSANAGI to gain more speed, and I believe it will help expand the PHP scene and respond to the needs of PHP engineers. At the Engineer Certification Corporation for PHP, we want to continue working with Prime Strategy and contribute to the advancement of PHP engineers’ technological skill.
