Sublime text 2: auto format php

You can use the Edit / Line / Reindent from the edit menu. Or you could try adding this to your keybindings - Default file from preferences.

{ "keys": ["f12"], "command": "reindent"}

Add a comma at the end of the code if you use the Default file instead of the users. Don't forget to select what you want indented.

You could potentially just use Visual Studio to auto-indent more obscure data that SubT can't or doesn't do well.

Good luck && select the text you want to reindent.

As zoli's answer states, you can use snippets/completions to auto complete tags as you start typing them. But there should be some built into sublime. For example, as you start to type <div>, you should see a drop down box with matching snippets. Hit Tab or Enter to pick one and arrow keys to go up or down in the list. For html tags, it will automatically adds the closing tag and puts the cursor in between them.

Another option is: use Edit > Tag > Close Tag. The hotkeys are displayed in the file menu. It automatically adds the closing tag if you already added an opening tag.
