Refactor the code in to be more concise in WordPress context

// Assume $map looks like this: 
$map = array( 
	array( 'name' => 'Name 1', 'something else' => 'whatever' ), 
	array( 'name' => 'Name 2', 'something else' => 'whatever' ), 
	array( 'name' => 'Name 3', 'something else' => 'whatever' ), 
	array( 'name' => 'Name 4', 'something else' => 'whatever' ), 
	array( 'name' => 'Name 5', 'something else' => 'whatever' ), 
	array( 'name' => 'Name 6', 'something else' => 'whatever' ), 
	array( 'name' => 'Name 7', 'something else' => 'whatever' ), 
	array( 'name' => 'Name 8', 'something else' => 'whatever' ), 
	array( 'name' => 'Name 9', 'something else' => 'whatever' ), 
); 

$names = array(); 

foreach ( $map as $data ) {
	$names[] = $data['name']; 
}
