Tidy is a binding for the Tidy HTML clean and repair utility which allows you to not only clean and otherwise manipulate HTML documents, but also traverse the document tree.
To use Tidy, you will need libtidy installed, available on the tidy homepage » http://tidy.sourceforge.net/.
Tidy is currently available for PHP 4.3.x and PHP 5 as a PECL extension from » http://pecl.php.net/package/tidy.
Note: Tidy 1.0 is just for PHP 4.3.x, while Tidy 2.0 is just for PHP 5.
If » PEAR is available on your *nix-like system you can use the pear installer to install the tidy extension, by the following command: pecl install tidy.
You can always download the tar.gz package and install tidy by hand:
Example#1 tidy install by hand in PHP 4.3.x
gunzip tidy-xxx.tgz
tar -xvf tidy-xxx.tar
cd tidy-xxx
phpize
./configure && make && make install
Windows users can download the extension dll from » http://pecl4win.php.net/ext.php/php_tidy.dll.
In PHP 5 you need only to compile using the --with-tidy option.
The behaviour of these functions is affected by settings in php.ini.

The constants below are defined by this extension, and will only be available when the extension has either been compiled into PHP or dynamically loaded at runtime.
Each TIDY_TAG_XXX represents a HTML tag. For example, TIDY_TAG_A represents a <a href="XX">link</a> tag. Each TIDY_ATTR_XXX represents a HTML atribute. For example TIDY_ATTR_HREF would represent the href atribute in the previous example.
