Continuous v. per-chapter/section numbering of figures, tables, and other document elements

I have written my thesis in document class 'article' (don't ask me why). Now I want to number my equations by sections, i.e. in section 1 they should go 1.1, 1.2, ..., in section 2 they should go 2.1, 2.2, ...

I don't want to change the document class (e.g. to 'report') because then I would have to change all sections to chapters, subsections to sections and because I fear a lot of other unintended consequences.

How can solve this?

Thanks for any help!
