// Listing all the variables
List ($ drink, $ color, $ power) = $ info;
Echo "$ drink is $ color and $ power makes it special. n ";

// Listing some of them
List ($ drink, $ power) = $ info;
Echo "$ drink has $ power. n ";

// Or let's skip to only the third one
List (, $ power) = $ info;
Echo "I need $ power! N ";

// List () doesn' t work with strings
List ($ bar) = "abcde ";
Var_dump ($ bar); // NULL
