Regex - match URL, but not deeper levels

I'm updating site where I have little control over the content structure or engine, so I must conditionally render a widget depending on URL match.

I need my code to execute when Regex match 

www.example.com/index.php/category

but NOT when it matches

www.example.com/index.php/category/subcategory

I've made this far by far: www\.example\.[^.]+/category, but unfortunatly this also matches both aformentioned cases, while I need it to match only a second one. Can you please suggest, how to stop Regex at first /category, instead of matching further URLs?

My guess is that this expression might likely work:

^(?:https?:\/\/)?(?:www\.)?[^.]+\.[^\/]+\/[^\/]+\/[^\/]+(?:\/)?$

We can also explicitly define the example.com:

^(?:https?:\/\/)?(?:www\.)?example\.com\/[^\/]+\/[^\/]+(?:\/)?$

DEMO

The expression is explained on the top right panel of regex101.com, if you wish to explore/simplify/modify it, and in this link, you can watch how it would match against some sample inputs, if you like.

You can use the follow pattern to match your Url string upto category

^www.example.com\/\S+\/category$

You can check here for further explanation and experiment on how it works.

Your regex won't match any of the cases since you are looking for characters except . in between www.example. and /category but clearly index.php has a . in it.

Use the following instead:

www\.example\.\S+\/category$

Here I am anchoring the end of the search string via $, and looking for at least one non-whitespace character in between www.example. and /category.
