See the “How to use” documentation at

http://wiki.novemberborn.net/sifr/How+to+use

for

more details about using sIFR.

After adding this last bit of code, you’re done! Your page will now work by default with replaced text. If

Flash or JavaScript aren’t supported by the user agent, it falls back gracefully to the default page font.

Stewart Rosenberger’s Text Replacement Method

This method uses JavaScript to replace page headings with images. The images are created by a PHP

script on-the-fly, so you don’t have to build the images yourself. It is otherwise very similar to sIFR.

For this technique to work, there are two prerequisites:

?

The PHP server must have the GD2 library installed. This is PHP’s image manipulation library,

and you can learn more about it at

http://www.php.net/image/

.

?

You need to have access to the font file of the font you want to use, because you’ll need to copy

it in your web site folder.

Assuming these two conditions are met, you can go on and modify the

popup.php

script that you

created earlier in this chapter, and have its header replaced by graphically rendered text when the page

loads. Figure 6-10 shows how the page will look after the exercise is completed, and Figure 6-2 shows

how the page looks right now.

Replacing Text with Images

1.

Start by enabling the GD2 PHP library, which you need for generating images on-the-fly with

PHP. If you set up your machine as described in Chapter 1, you have GD2 already installed, but

it may not be enabled by default. Open for editing the

php.ini

configuration file. In the typical

XAMPP configuration, this file is located in the

\xampp\apache\bin

folder. In other scenarios,

you’ll find it in your Windows folder.
