Question

For example I have a menu item named Categories and under that I have 10 different sub categories. So the url currently would be something like this:

http://domain/categories
http://domain/categories/sub1
http://domain/categories/sub2
...etc

I want to do something if the url is on categories regardless of what sub categories it is in.
So instead of typing out each sub categories sub1, sub2…sub10..etc. How can I tell PHP to check if the URL is http://domain/categories/ and all sub after this…almost like an “ALL” wildcard…

Answer 1

The most simple (primitive) approach is:

if(substr_count($actual_url, 'http://domain/categories'))
{
    //do whatever you like
}
