    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' )
