# CXLV. Tidy Functions

# 简介

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.

# 需求

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

# 安装

Tidy is currently available for PHP 4.3.x and PHP 5 as a PECL extension from http://pecl.php.net/package/tidy.

> 注: 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:

例子 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.

# 运行时配置

这些函数的行为受 `php.ini` 的影响。

表格 1. Tidy Configuration Options

Name | Default | Changeable | Changelog
--- | --- | --- | ---
tidy.default_config | "" | PHP_INI_SYSTEM | Available since PHP 5.0.0.
tidy.clean_output | "0" | PHP_INI_PERDIR | Available since PHP 5.0.0.

有关 PHP_INI_* 常量进一步的细节与定义参见附录 G。

以下是配置选项的简要解释。

tidy.default_config string

  Default path for tidy config file.

tidy.clean_output boolean

  Turns on/off the output repairing by Tidy.

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

# 资源类型

本扩展模块未定义任何资源类型。

# 预定义类

## tidyNode

### 方法

- tidyNode->hasChildren - Returns `TRUE` if the current node has childrens

- tidyNode->hasSiblings - Returns `TRUE` if the current node has siblings

- tidyNode->isAsp - Returns `TRUE` if the current node is ASP code

- tidyNode->isComment - Returns `TRUE` if the current node is a comment

- tidyNode->isHtml - Returns `TRUE` if the current node is HTML

- tidyNode->isJste - Returns `TRUE` if the current node is JSTE

- tidyNode->isPhp - Returns `TRUE` if the current node is PHP

- tidyNode->isText - Returns `TRUE` if the current node is Text (no markup)

### 属性

- value - the value of the node (e.g. the html text)

- name - the name of the tag (e.g. html, a, etc..)

- type - the type of the node (one of the constants above, e.g. `TIDY_NODETYPE_PHP`)

- line* - the line where the node starts

- column* - the column where the node starts

- proprietary* - `TRUE` if the node refers to a proprietary tag

- id - the ID of the tag (one of the constants above, e.g. `TIDY_TAG_FRAME`)

- attribute - an array with the attributes of the current node, or `NULL` if there aren't any

- child - an array with the child tidyNodes, or `NULL` if there aren't any

> 注: The properties marked with * are just available since PHP 5.1.0.

# 预定义常量

以下常量由本扩展模块定义，因此只有在本扩展模块被编译到 PHP 中，或者在运行时被动态加载后才有效。

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.

The following constants are defined:

# 范例

This simple example shows basic Tidy usage.

例子 2. Basic Tidy usage

`<?php ob_start(); ?> <html>a html document</html> <? $html = ob_get_clean(); // Specify configuration $config = array( 'indent' => true, 'output-xhtml' => true, 'wrap' => 200); // Tidy $tidy = new tidy; $tidy->parseString($html, $config, 'utf8'); $tidy->cleanRepair(); // Output echo $tidy; ?>`
