                                     array

   (PHP 3, PHP 4 )
   array --  Create an array

Description

   array array ( [mixed ...])

   Returns an array of the parameters. The parameters can be given an
   index with the => operator. Read the section on the array type for
   more information on what an array is.

     Note: array() is a language construct used to represent literal
     arrays, and not a regular function.

   Syntax "index => values", separated by commas, define index and
   values. index may be of type string or numeric. When index is omitted,
   an 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.

   Example 1. array() example
   <?php
   $fruits = array (
       "fruits"  => array("a" => "orange", "b" => "banana", "c" =>
   "apple"),
       "numbers" => array(1, 2, 3, 4, 5, 6),
       "holes"   => array("first", 5 => "second", "third")
   )
   ?>

   Example 2. Automatic index with array()
   <?php
   $array = array(1, 1, 1, 1,  1, 8 => 1,  4 => 1, 19, 3 => 13);
   print_r($array);
   ?>

   will display:
   Array
   (
       [0] => 1
       [1] => 1
       [2] => 1
       [3] => 13
       [4] => 1
       [8] => 1
       [9] => 19
   )

   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.

   This example creates a 1-based array.

   Example 3. 1-based index with array()
   <?php
   $firstquarter = array(1 => 'January', 'February', 'March');
   print_r($firstquarter);
   ?>

   will display:
Array
(
    [1] => January
    [2] => February
    [3] => March
)
