How to comma separate the values of an array for display

I have searched the PHP.net site and originally thought of some use for the

list()
function but doesn't seem to accomplish the goal:

I have an unknown number of values stored in a single array

$array1 = array(1,2,3,4,5);


or

$array1 = array(1,2,3);


I want to be able to echo (or
print_r
) the values contained within an array to screen and separated only by commas and spacing.

For example:

the 'idea' is to have echo
$array1
to display:

1,2,3

from the second example above.
