Enable Vim Syntax Highlighting By Default

Also, to highlight the syntax of a Specific File TYPE (or programming language extension), you can use following commands, while file is already opened in Vim and you want to try syntax highlighting on the fly:

:set filetype=php

OR shortcut:

:se ft=php

Above commands will change the syntax-highlighting for currently opened file as it should be for PHP code.

Edit your $HOME/.vimrc (Unix/Linux/OSX) or $HOME/_vimrc (Windows) to include the following line:

syntax on

EDIT

If your syntax highlighting doesn't work when you start Vim, you probably don't have a $HOME/.vimrc or $HOME/_vimrc (known collectively as vimrc from now on). In that case, you have two options:

• Create an empty vimrc.
• Copy vimrc_example.vim as your vimrc (recommended, thanks @oyenamit). You can find vimrc_example.vim in the runtime directory.

The location of the runtime directory varies between operating systems:

• On my system (Arch Linux, and Mac, thanks @totophe), it's in /usr/share/vim/vim73.
• On Windows, it's in \Program Files\Vim\vim73.
