Print out array keys only

[undbund]

Hi, there are lots of examples that show you how to print array values
given a key. Do you know how to print keys for a given array.

example

$myArray = array('a'=>1, 'b'=>2, 'c'=>3, 'd'=>4);

How do you print 'a', 'b', 'c','d' only without using any loops?

Thanks in advance for all your help
