boolean virtual(string filename)
The virtual function is available only when PHP is an Apache module. It is equivalent to
writing <!— #include virtual filename—>, which is an Apache subrequest.
You may wish to refer to the Apache documentation to learn more. Use the include and
require functions if you want to parse a PHP script. FALSE is returned on error.
<?
virtual("ssi-example.shtml");
?>
Aspell
The Aspell library is used to verify the spelling of a word. It is the result of an open
source project run by Kevin Atkinson. The official Web site is
http://metalab.unc.edu/kevina/aspell/. In order for PHP to use Aspell, the
functions must be loaded as an extension. At the time of this writing, no win32 extension
existed for Aspell, so its functionality is available to UNIX users only. Mark Musone
added Aspell support to PHP.
integer aspell_new(string dictionary, string personal_words)
Use aspell_new to load a dictionary into the system. An identifier is returned that
must be used in subsequent calls to Aspell functions. The second argument is optional
and specifies a personal dictionary.
<?
//create a test sentence
$text = "Thiss sentense haz some spellling erors.";
//load dictionary
$aspell_link = aspell_new('english');
//tokenize sentence
for($word = strtok($text, ' ');
$word != ''; $word = strtok(' '))
{
//check for unrecognized words
if(!aspell_check($aspell_link, $token))
{
//try checking raw version
if(!aspell_check_raw($aspell_link,
$token))
