But what makes it unique is a Just in Time engine, that allows compilation of the code during the execution of the program. This principle is also known as dynamic translation.

I mean, I guess this weird explanation is fine for a php consultant, but honestly I wouldn't trust any results presented next a description this wrong.

The first part is kind of baffling. I'm not even sure what is trying to be said there. English as a second language?

The second one if actually wrong unless something changed very recently, PHP is not JIT compiled (at least not to machine code). It is a bytecode VM. I remember the discussion came up and optimizing the byte code was actually improved performance more than proof of concept JIT did for common PHP use cases.

PHP 8 is supposed to have a JIT I believe.
