How does the concept of treemaps in PHP differ from other programming languages, such as Java?

In PHP, the concept of treemaps is not natively supported in the standard library. However, you can implement treemaps using arrays and custom functions to mimic the functionality of treemaps. 

class TreeMap {
    private $map = [];

    public function put($key, $value) {
        $this->map[$key] = $value;
    }

    public function get($key) {
        return $this->map[$key] ?? null;
    }

    public function remove($key) {
        unset($this->map[$key]);
    }

    public function size() {
        return count($this->map);
    }

    public function clear() {
        $this->map = [];
    }
}

// Example usage
$treeMap = new TreeMap();
$treeMap->put('key1', 'value1');
$treeMap->put('key2', 'value2');

echo $treeMap->get('key1'); // Output: value1
