By default, Netbeans is mostly configured to format code in the way that matches the WordPress Coding Standards, except for the spacing within parantheses. You can edit them under Tools → Options → Editor → Formatting → Language = PHP → Category = Spaces. Here’s a screenshot of the correct settings (click to enlarge):

You can also amend the PHP (and All Languages) tabs and indents to match the following, if it’s not already:

Now, any time you need to match the formatting, you can select all the text, then hit ALT-SHIFT-F (or right-click → Format). The only one it doesn’t seem to catch is the negation operator (!), so you’ll still manually need to turn:
if ( !foobar ) {
into:
if ( ! foobar ) {
