How do I remove html from explode?

[Yosho]

FYI New to PHP.

$tree = explode('</div>',$q->getCategories());

getCategories shows me a breadcrumb that is already wrapped in html

What I am trying to do is remove some html tags such as </div> and <hr />
The code that is shown above already removes </div> successfully but i can't remove <hr />

I already tried this

$tree = explode('</div>',$q->getCategories());
$tree1 = explode('<hr />',$tree[1]);

or this

$tree = explode('<hr />','</div>',$q->getCategories());

I don't know how to remove two specific html tags from one variable or string.... my lack of php vocabulary shows that I am new to PHP.

Would [man]strip_tags/man be useful for you here? Unfortunately, it removes all tags except for those allowed, rather than removing only those not allowed (though for its normal use case, this is a Good Thing).

Thank you very much this is exactly what I needed!
