The PHP development team decided to use the backslash (\) as namespace separator in future releases of PHP (up from 5.3) The decision wasn’t very welcomed by the community and numerous people already started basing PHP again. i feel that some of the people involved are beeing very single minded on this. I think time will tell who was right and who wasn’t. I personally would liked to be :: instead of \ but i will live with this. This shouldn’t be a motive for anyone to spread the FUD (Fear Uncertainty Doubt) around about PHP.
