Manipulating
Arrays
Discovery
Project 6-3
Create
a PHP script with an associative array that uses image file-
names
as the keys and image captions as the values. Use the keys and
you
display a small hyperlinked image to open a larger version of
the
image. Use the zodiac sign images that you saved in your Images
folder
in Chapter 1. Set a width and height for the thumbnails that are
less
than half of the height and width of the images. Format the dis-
play
of the thumbnail gallery.
Save
the file as ZodiacGallery.php and upload it to the
ChineseZodiac
folder on the Web server. Test the script.
Reopen
inc_web_forms.php and add another text link (Image
Gallery)
to the text navigation bar that links to the Image Gallery
descriptive
text. Below the Alphabetizing Signs descriptive text,
add
a new section called “Image Gallery” with descriptive text and
hyperlinks
for “[Test the Script]” and “[View the Source Code]” for
ZodiacGallery.php.

and modify the script to create a multidimensional array named

For
example, $AnimalSigns["Monkey"]
is
an array that con-
tains
three elements: $AnimalSigns["Monkey"]["Start
Date"]
is
1908, $AnimalSigns["Monkey"]["End
Date"] is
2028, and
$AnimalSigns["Monkey"]["President"]
is
“Harry Truman.”
Access
the multidimensional array to display the following message
in
addition to the message and image displayed by the original script
(text
in bold will change depending on the sign being displayed): “If
your
Chinese zodiac sign is the Rat, you share a zodiac sign with
President
George Washington. Years of the Rat include 1900, 1912,
1924,
1936, 1948, 1960, 1972, 1984, 1996, 2008, and 2020.”
To
display the message shown above, you can use the following code.
The
variable $ChosenSign
contains
the name of the animal. The year
string
is stored in the $SignMessage
variable.
$SignMessage
= "If your Chinese zodiac sign is
the
$ChosenSign, you share a zodiac sign
with President " .
$AnimalSigns[$ChosenSign]["President"] .
". ";
$SignMessage .= "Years of the $ChosenSign
include ";
for ($i = $AnimalSigns[$ChosenSign]["Start Date"];
$i < $AnimalSigns[$ChosenSign]["End Date"];
$i+=12)
$SignMessage .= $i . ", ";
$SignMessage .= "and " .
$AnimalSigns[$ChosenSign]["End Date"] . ".";

Save the BirthYear_switch.php script and upload the file to the
ChineseZodiac folder on the Web server. Open the main page
(index.php) for the Chinese Zodiac site. Click the Control Structures
button or Control Structures text link and select the Switch
Statement link to test the functionality of the script.
