Multi dimensional Arrays

In a multi dimensional array, each element in the main array can also be an array. And each element in the sub-array can be an array, and so on.

Example

In this example we create a multidimensional array, with automatically assigned ID keys:

$families = array("Griffin"=>array("Peter","Louis","Maya"),"Mary"=>array
  ("Glenn"),"Brown"=>array("New Zealand","Lora","John")); 

The array above would look like this if written to the output:

Array(
[Griffin] => Array([0] => Peter  [1] => Louis  [2] => Maya  )
[Mary] => Array([0] => Glenn)
[Brown] => Array([0] => New Zealand [1] => Lora [2] => John)		)
