an index with the <literal>=></literal> operator.

Syntax "index => values", separated by commas, define index
|
|
and values. index may be of type string or numeric. When index is
|
|
omitted, a integer index is automatically generated, starting
|
|
at 0. If index is an integer, next generated index will
|
|
be the biggest integer index + 1. Note that when two identical
|
|
index are defined, the last overwrite the first.

The following example demonstrates how to create a
|
|
two-dimensional array, how to specify keys for associative
|
|
arrays, and how to skip-and-continue numeric indices in normal
|
|
arrays.

Note that index '3' is defined twice, and keep its final value of 13.
|
|
Index 4 is defined after index 8, and next generated index (value 19)
|
|
is 9, since biggest index was 8.
