I haven't made any thorough analysis of which implementation of PHP is the best and I haven't found anyone either on the Internet. So, If someone out there just can point out some benefits and flaws regarding each language compared to the other, than I would really appreciate it. Which one compiles the fastest?
A follow up question:
Is all programming langauge(languauge that needs to be compiled first) equally fast?
HipHop was developed by Facebook to boost the performance on their application. You might know it ;) HipHop is definetly really fast and it is faster then cgi. But there some minor drwabacks, you have to avoid some functions. See this article on sitepoint. http://www.sitepoint.com/boost-php-performance-with-hiphop/
