There is a bug in Netbeans 8 PHP (maybe also in other languages?) that indents every line inserted using code completion. Maybe this problem isn't present in a fresh installation and on the contrary is the result of auto-updating from 8.0.1 to 8.0.2. I'm not sure about it.

In other words, if you use code completion you end up with something like this:

$db->connect();
  $db->connect();
    $db->connect();
      $db->connect();

Open the file ~/.netbeans/8.0.2/config/Editors/Preferences
(If you are using Windows it's you problem and not the worst! )

look for the line

<entry javaType="java.lang.String" name="code-template-on-expand-action" xml:space="preserve">
  <value><![CDATA[INDENT]]></value>
</entry>

and rem the entire block (or delete it).

Restart Netbeans and that's it!
