Solved myself,
here are the steps :-

1. locate vim | grep php
2. turn up is this file /usr/share/vim/vim73/syntax/php.vim
3. sudo mv /usr/share/vim/vim73/syntax/php.vim /usr/share/vim/vim73/autoload/phpcomplete.vim.orig as backup
4. download latest php vim file from http://www.vim.org
5. untar the tarball
6. copy the php.vim to /usr/share/vim/vim73/syntax/php.vim

Answer 2

I think the proper solution is to install the updated syntax file locally, in your ~/.vim/syntax directory. From your answer, you have installed the syntax file in /usr/share/vim, which is system class directory. This is not recommended since this can be erased on system or application update, and you don't know what your modification might conflict with. Instead, you should put all your vim configuration files under your home directory in ~/.vim.
