例子
复制代码 代码如下:
$config->set('HTML.AllowedElements', array('div'=>true, 'table'=>true, 'tr'=>true, 'td'=>true, 'br'=>true));
$config->set('HTML.Doctype', 'XHTML 1.0 Transitional') //html文档类型(常设)
$config->set('Core.Encoding', 'UTF-8') //字符编码(常设)
HTML允许的元素
div元素,table元素,tr元素,td元素,br元素
new HTMLPurifier对象
复制代码 代码如下:
$purifier = new HTMLPurifier($config);
调用HTMLPurifier对象的purify方法
复制代码 代码如下:
$puri_html = $purifier->purify($html);
第二种方式
自定义一个类 HtmlPurifier.php
复制代码 代码如下:
require_once 'HTMLPurifier.includes.php';
require_once 'HTMLPurifier.autoload.php';
class Resume_HtmlPurifier implements Zend_Filter_Interface{
protected $_htmlPurifier = null;
public function __construct($options = null)
{
$config = HTMLPurifier_Config::createDefault();
$config->set('Code.Encoding', 'UTF-8');
$config->set('HTML.Doctype', 'XHTML 1.0 Transitional')
if(!is_null($options)){
foreach($options as $option){
$config->set($option[0], $option[1], $option[2]);
}
}
$this->_htmlPurifier = new HTMLPurifier($config);
}
public function filter($value)
{
return $this->_htmlPurifier->purify($value);
}
}
?>
设置config信息
例如:
复制代码 代码如下:
$conf = array(
array('HTML.AllowedElements',
array(
'div' => true,
'table' => true,
'tr' => true,
'td' => true,
'br' => true,
),
false), //允许属性 div table tr td br元素
array('HTML.AllowedAttributes', array('class' => TRUE), false), //允许属性 class
array('Attr.ForbiddenClasses', array('resume_p' => TRUE), false), //禁止classes如
array('AutoFormat.RemoveEmpty', true, false), //去空格
array('AutoFormat.RemoveEmpty.RemoveNbsp', true, false), //去nbsp
array('URI.Disable', true, false),
);
调用
复制代码 代码如下:
$p = new Resume_HtmlPurifier($conf);
$puri_html = $p->filter($html);

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
