You can use the second parameter of json_decode to get a php array and work with php built-in functions.
$string = '[{"id":3},{"id":4,"children":[{"id":5,"children":[{"id":6}]}]}]';
$result = array_filter(json_decode($string, true), function($elem){return $elem['id']!=4;});
array_filter keeps only the elements for which the callback function returns true, so this keeps all elements where id is not 4
