Thousands? No, many, many, millions. If you break PHP, you break Yahoo,
Wikipedia, Wordpress, Facebook.... many millions of sites. Maybe billions
at this point.
But changing default behavior does not break things? But this seems to be ok -
at least sometimes. So there are acceptable changes that break millions of
sites and then there are others.
How many of the big sites are actually using a stock build of PHP? I'm not talking about the privately run wordpress and jumla copies, but the core websites themselves? They forked PHP a long time ago?
I have complained in the past and been shouted down over the fact that while 'yes' one can configure a PHP5.4 installation to run PHP5.2 code, there is a much higher chance that it will simply give you a white screen. I'm not currently running 5.5 ... there are not enough hours in the day! But I believe that many of you now understand that anything not rewritten to be e_strict complaint can't safely be left on a modern PHP infrastructure? Ploughing on blindly ignoring or suppressing 'opposing' views is the censorship I am talking about. Be that on the main php.net controlled sites or on the newly promoted third party ones!
Where is the roadmap for PHP controlled from? It seems at present that there is simply no control at all over how the project is managed.
