    Default usage example.

    Let’s assume the current post has 3 values associated with the (custom) field my_key.

    You could show them through:

    $mykey_values = get_post_custom_values( 'my_key' );

foreach ( $mykey_values as $key => $value ) {
	echo "$key => $value ( 'my_key' )<br />"; 
}

    The above example will output:

    0 => First value ( 'my_key' )
1 => Second value ( 'my_key' )
2 => Third value ( 'my_key' )
