## Example

default

```clean(Input::get('inputname'));```
or

```Purifier::clean(Input::get('inputname'));```
dynamic config

```clean('This is my H1 title', 'titles');```
```clean('This is my H1 title', array('Attr.EnableID' => true));```
or

```Purifier::clean('This is my H1 title', 'titles');```
```Purifier::clean('This is my H1 title', array('Attr.EnableID' => true));```

## 使用情例 :+1: 

今天允許表格的樣式寫入
其中 Table以 
```<table></table>```
```<tbody></tbody>```
```<tr></tr>```
```<td></td>```
```<th></th>```組成 

其中 ```<table><td>```標籤裡又會有 **style**、**class**、**width**、**border** 等樣式

於底下 **HTML.Allowed** 修改成 標籤的字串 如標籤內含有多個樣式請使用 **[]** 並於裡面使用 **|** 分隔

並於**CSS.AllowedProperties**中設定會使用到的**css**樣式名稱
 ```php=
[
    'settings' =>[
        default' => [
            'HTML.Allowed'=> 'table[border|width|style|class],tbody,tr,td[border|width|style|class],th',
            'CSS.AllowedProperties'    => 'background-color,text-align,width,height,vertical-align',
        ],
    ]
]
```
