This fresh execution design had numerous benefits - almost all notably efficiency, which exploded through the roofing likened to PHP 3. WhiIe this engine evolved significantly in the final 15+ decades, these concepts, and also most of the way that Intermediate Code appears like, haven't changed since its launch. Conceptually, the Zend Motor compiles PHP supply code into an in-memory portrayal, called More advanced Code a independent component then iterates over this intermediate program code and éxecutes it. PHP 4, which highlighted the initial edition of the Zend Engine, has been the first version whose setup engine resembled in numerous methods the setup engine that can be still with us to this day - throughout PHP 5 and even PHP 7. This transformed with PHP 4, which came out in mid-2000. But as thése stats kept on keeping consistent, and as the demands for a source-code defense answer - arriving from genuine people, not just numbers in reports - became more and even more several, Andi and I believed that probably, just probably, we could perform something abóut it. We thought they must have got a measurement error and were away from by at minimum an order of magnitude or twó.
For us, the reality PHP was getting such an enormous success has been currently a little bit difficult to get used to - we in fact acquired a quite hard time trusting the statistics we had been getting from Netcraft back again in the day about simply how quickly PHP was developing. To provide credit where credit's owing, the concept for the item in fact wasn't Andi's i9000 or mine with the explosive growth PHP had been encountering in the change of the one hundred year and the dotcom growth, companies were actually coming to us, requesting for a remedy that would enable them to market their apps without giving away their supply code.
Zend Guard dates back to 2001, and had been in fact the first commercial product idea Zend got, and arguably, the one that got us to begin the organization in the 1st place.
