Q The design of this application makes use of PHP function definitions to enable

modular reusable code.

Q The PHP functions defined in the anyco_ui.inc file contain parts of the

original HTML contents from the first anyco.php you created.

Q The functions in anyco_ui.inc, make use of a PHP language construct

called a "here document". This enables you to place any amount of HTML

formatted text between the following two lines:

echo <<<END

END;

The END; line must not be prefixed with leading spaces otherwise the rest of

the document is treated as part of the text to be printed. Any PHP parameters

appearing inside the body of a "here document" are replaced with their values,

for example the $title or $date parameters.

Q The PHP function htmlentities() is used to prevent user-supplied text

from containing HTML markup.

3. The PHP file makes use of a Cascading Style Sheet (CSS) file called style.css to

specify presentation style in HTML in the browser.

Use your editor to create style.css in the chap3 directory with the following

CSS text:

body

{ background: #CCCCFF;

color: #000000;

font-family: Arial, sans-serif; }
