Text_Figlet has only two methods you can use:
loadFont() to select a FIGlet font file that will be used
later on, and lineEcho() that actually returns the
passed text, rendered with the previously selected font.
loadFont() takes the name/path of the FIGlet font file
(*.flf or *.flf.gz) as first parameter,
and the option if German characters should also be loaded as second, optional
parameter (defaults to true).
The method either returns true if the font could
be loaded, or a PEAR_Error in case of a problem.
lineEcho() can be called (multiple times if needed) after
loading the font with loadFont(). The method takes the text
that should be rendered using the font as first parameter, and an optional
second parameter that determines if the text should be outputted in HTML
text. In this case, special characters are escaped and everything is setup
so that the text will look correctly. This parameter defaults to
false. You should also wrap the line into <pre> tags,
since they will monospace the text. Unlike the name implies, the rendered text
is not echoed but returned.
Example 64-6. Rendering "Hello, world!" using PHP <?php
require_once 'Text/Figlet.php';
$figlet = new Text_Figlet();
$error = $figlet->LoadFont('slant.flf');
if (PEAR::isError($error)) {
echo 'Error: ' . $error->getMessage() . "\n";
} else {
echo $figlet->LineEcho('Hello, world!') . "\n";
}
?> |

The Text_Figlet package already ships some fonts.
They are stored in its data directory which can be found calling
pear config-get data_dir, and appending
Text_Figlet/fonts/ to it. It will contain the following
fonts:
3-d.flf
alligator2.flf
bell.flf
block.flf
contessa.flf
cybermedium.flf
isometric1.flf
larry3d.flf
script.flf
slant.flf
Passing one of the font names to
loadFont() will
automatically look them up in the
Text_Figlet font
data directory if they are not found.
