HH\Map::values

Returns a Vector containing the values of the current Map

public function values(): Vector<Tv>;

This method is interchangeable with toVector().

Returns

Vector<Tv> - a Vector containing the values of the current Map.

Examples

This example shows how values() is identical to toVector(). It returns a new Vector of $m's values, so mutating this new Vector doesn't affect the original Map.

$m = Map {
  'red' => '#ff0000',
  'green' => '#00ff00',
  'blue' => '#0000ff',
  'yellow' => '#ffff00',
};

// Get a Vector of $m's values
$v = $m->values();

// Modify $v by adding an element
$v->add('#663399');
\var_dump($v);

// The original Map $m doesn't include the value '#663399'
\var_dump($m);
