CIX. Tidy Functions

Introduction

Tidy is a binding for the Tidy HTML clean and repair utility which allows you to not only clean and otherwise manipluate HTML documents, but also traverse the document tree.

Requirements

To use Tidy, you will need libtidy installed, available on the tidy homepage http://tidy.sourceforge.net/.

Installation

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: pear -v 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 php_tidy.dll from http://snaps.php.net/win32/PECL_STABLE/.

In PHP 5 you need only to compile using the --with-tidy option.

Runtime Configuration

The behaviour of these functions is affected by settings in php.ini.

For further details and definition of the PHP_INI_* constants see ini_set().

Warning

Do not turn on tidy.clean_output if you are generating non-html content such as dynamic images.

Resource Types

This extension has no resource types defined.

Predefined Constants

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.

The following constants are defined:
