How do i loop through an $_GET array and display all variables except the current value. I have a search page that work with $_GET to filter. What i want to do is add buttons to exclude form the next search the current array value but still pass all the other values for example:

<h4>Filters Applied</h4> (click X to remove filters) 
foreach($_GET as $key => $value)
{
echo '<a href="binx/search_advanced.php?'. DISPLAY ALL EXCEPT CURRENT .'"> X - ' . $key . '</a>';
}

I am rather new to PHP so unsure if this is possible and how to achieve it if it is.

What I have tried:

I have tried searching on google but cant seem to find and answer that works in my case.

"display all variables except the current value"
How do you decide what is the current value?

It's pretty easy logic:

You need to know what you want to exclude.

- If it's an associative array, use a foreach() loop and when you find the match to the one you're wanting to exclude simply skip it and continue the loop.
- If it's an indexed loop (i.e., integers), you can do the same and, if order's important, you can use a for() loop and skip the index(s) you wish;

So: loop, test, act on item or continue. Testing the members of an array is very basic.

Now - as for "searching google" for an answer that works in your case, you should be trying to learn to code - not copy. You'll

What needs to happen is this should give me a link to exclude the current variable in the array. While looping through the array, so i need a loop inside of a loop ?

Let`s say I have an array to search for A, B, C, D. the link I need is to exclude each on their own to widen the search parameters all 4 should exclude the current value but keep the remainder:

so
link A will include parameters from the array B, C, D
link B will include parameters from the array A, C, D
link C will include parameters from the array A, B, D
link D will include parameters from the array A, B, C
