The C language is similar to most modern programming languages in that it allows the use of functions, self contained "modules" of code that take inputs, do a computation, and produce outputs. But in assembly data types may be DB(Data Byte) or DW (Data Word). PHP: Multidimensional Arrays Array does not have to be a simple list of keys and values; each array element can contain another array as a value, which in turn can hold other arrays as well.
