array_values

The array_values() function in PHP takes an array and returns all it’s values as a numeric array.

PHP

$array = array('go' => 'green', 'stop' => 'red');
var_dump( array_values($array) );
/*
Array (
	[0] => green
	[1] => red
)
*/

To replicate this functionality in Ruby, we need to use a Hash object, since arrays in Ruby don’t use associative key/value pairs.

Ruby

array = { :go => 'green', :stop => 'red' };
puts array.values;
# => ["green", "red"]
