toVector

Note

This is a point-in-time snapshot of the API documentation from January 2026. Going forward, we will not be maintaining a public copy of these references, and recommend users to refer to the built-in signature helpers available in the Hack LSP instead for complete and up-to-date information.

Returns a Vector with the values of the current Map

public function toVector(): Vector<Tv>;

Returns​

  • Vector<Tv> - a Vector that contains the values of the current Map.

Examples​

This example shows how toVector() returns a 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',
};

// Make a deep Vector copy of the values of $m
$v = $m->toVector();

// 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);
