PHP: Remove url parameters on click

Question

I have a url that in the worst case scenario looks like this website.com/clothes/women/type/tshirts/brand/nike/color/red/size/s/price/0-29

This is created by clicking on links that will filter the results starting from website.com/clothes/women. The problem is how can I reverse it ? I show all the filters clicked with a X near it, so when clicked, a certain filter will be deleted and the page refreshes. If I delete the color filter, /color/red or color/red/ must be deleted from the url.

How can this be done ? I tried with str_replace() but with no luck.

Just an input and I will find the way.

Thank you.

@meagar: what is the difference actually? Why is it worse than ?type=tshirts&...? — zerkms

@meagar I don't know what you mean, this is a query string, it's just formatted with .htaccess so it does not look like ?type=tshirts&brand=nike&... Can you suggest a better one ? — C. Ovidiu

@C.Ovidiu use POST and session data with cookies like every other site on the planet. — Deryck

@Deryck: it's actually the terrible advice (not to say it's silly). Check amazon and ebay — zerkms

@zerkms I didn't look closely enough; I thought it was just an arbitrary series of key1/value1/key2/value2/key3/value3... but you're right, it specifically looks like it gets progressively more specific. — user229044

I think str_replace() should work:

function remove_filter($url, $type, $value) {
    return str_replace("/$type/$value", "", $url);
}

This is not a job for str_replace or regexes.

Use explode to put the components of the path into an array. Manipulate the array. Reassemble the path with join.
