I have an array $list that I'm trying to sort. I'm using a function that does that like so:

function sortNodes($a, $b) {
    return strcmp($a->$title, $b->$title);
}
usort($list, 'sortNodes');

but I need to pass an extra parameter to that function. Something like:

function sortNodes($a, $b, $node) {
   return strcmp($a->$node, $b->$node);
}
usort($list, 'sortNodes');

The $node parameter needs be fetch from URL with $_GET but this way it isn't functioning. How can i do this?

thanks in advance.

One way of providing extra information to a closure is to pass it via a _use_ clause? e.g. `function sortNodes($a, $b) use ($node) { `... – Ryan Vincent Feb 09 '18 at 16:16
