> = .. PHP Laravel后的运算符

Just came by this code in Laravel Paginator.php today

$this->hasMore = $this->items->count() > $this->perPage;

I'm familiar with -> and > but not sure how this bigger than fits after an = . this is the full function :

protected function setItems($items)
{
    $this->items = $items instanceof Collection ? $items : Collection::make($items);

    $this->hasMore = $this->items->count() > $this->perPage;

    $this->items = $this->items->slice(0, $this->perPage);
}

    The right side is evaluated and the result is assigned to the left. This of it this way:

    $a = ($b > $c);
    

    Where this evaluates to a boolean:

    ($b > $c)
    

    Alternatively:

    $a = ($b > $c) ? true : false;
    

    Or:

    if ($b > $c) {
        $a = true;
    } else {
        $a = false;
    }
