Or you can use reject method   newColection    collection- gt reject function  element        return  item- gt selected    true        or pull method   selected        foreach   collection as  key   gt   item          if   item- gt selected    true               selected      collection- gt pull  key

You would want to use - gt forget     collection- gt forget  key     Link to the forget method documentation

I m not fine with solutions that iterates over a collection and inside the loop manipulating the content of even that collection  This can result in unexpected behaviour  See also here  https   stackoverflow com a 2304578 655224 and in a comment the given link http   php net manual en control-structures foreach php 88578 So  when using foreach if seems to be OK but IMHO the much more readable and simple solution is to filter your collection to a new one         Filter all  selected  items        link https   laravel com docs 7 x collections method-filter      selected    collection- gt filter function  value   key        return  value- gt selected    - gt toArray

Laravel Collection implements the PHP ArrayAccess interface  which is why using foreach is possible in the first place    If you have the key already you can just use PHP unset   I prefer this  because it clearly modifies the collection in place  and is easy to remember   foreach   collection as  key   gt   value        unset  collection  key

If you know the key which you unset then put directly by comma   separated   unset  attr  placeholder     attr  autocomplete
