I have problem with tab's. phpED inserts two tab's plus one space at code, when I hit tabulator once, so it would be like:

I except it would look like this:


Haven't found anythink helpful from settings.

It's how SmartTab feature works in PHPED 3.2.
In this case whenever you press TAB the editor adjusts cursor position according to the spaces/tabs in the line above. In your particular case it properly adjusted to f() because there is a space before.
If you need TAB to always get specified number of spaces or tab characters you have to turn Smart Tab off and check if you need Use Tab Character.

This issue is addressed in phped 3.3
