Can you “compile” PHP code and upload a binary-ish file, which will just be run by the byte code interpreter?
After this question was asked, Facebook launched HipHop for PHP which is probably the best-tested PHP compiler to date (seeing as it ran one of the world’s 10 biggest websites). However, Facebook discontinued it in favour of HHVM, which is a virtual machine, not a compiler. Beyond that, googling PHP compiler turns up a number of 3rd party solutions. … Read more
