This section provides a tutorial example on how to create arrays in different ways.

Here is a tutorial example PHP script to show you some of array rules described in the previous section:

<?php # ArrayTest.php
# Copyright (c) 2003 by Dr. Herong Yang, http://www.herongyang.com/
# 
   print "\nLibrary hours:\n";
   $libraryHours = array(
      'Monday - Friday'=>'09:00 - 21:00', 
      'Saturday'=>'09:00 - 17:00', 
      'Sunday'=>'closed');
   print_r($libraryHours);
#
   print "\nPrime numbers:\n";
   $primeNumbers = array(3, 5, 7, 11);
   $primeNumbers[] = 13;
   print_r($primeNumbers);
#
   print "\nFruits:\n";
   $fruits[] = 'Apple';
   $fruits[] = 'Orange';
   $fruits[''] = 'Peach';
   $fruits[''] = 'Banana';
   $fruits['G'] = 'Grape';
   $fruits['7'] = 'Pear';
   $fruits[] = 'Fig';
   print_r($fruits);
#
   print "\nFruits array modified:\n";
   unset($fruits[1]);
   $fruits[1] = 'Orange';
   print_r($fruits);
?>

If you run this sample script, you should get:

Library hours:
Array
(
    [Monday - Friday] => 09:00 - 21:00
    [Saturday] => 09:00 - 17:00
    [Sunday] => closed
)

Prime numbers:
Array
(
    [0] => 3
    [1] => 5
    [2] => 7
    [3] => 11
    [4] => 13
)

Fruits:
Array
(
    [0] => Apple
    [1] => Orange
    [] => Banana
    [G] => Grape
    [7] => Pear
    [8] => Fig
)

Fruits array modified:
Array
(
    [0] => Apple
    [] => Banana
    [G] => Grape
    [7] => Pear
    [8] => Fig
    [1] => Orange
)

The behavior of the $fruits array is very interesting. Review it carefully.
