dr-filter
=========

[](#dr-filter)

DrFilter输入过滤帮助类
---------------

[](#drfilter输入过滤帮助类)

用于对传入内容进行过滤,支持传入数组，违规的输入会被替换为null后返回。

内置1个默认过滤字符集和5个过滤等级,分别对应描述如下:

0:防xss攻击,并去除输入中的空格和换行回车

1:仅支持输入数字字母下划线和中日韩文字

2:仅支持输入数字字母下划线和中文

3:仅支持输入数字字母下划线

4:仅支持输入数字

默认过滤等级为0

注意: 本扩展默认不会对符号 # 进行过滤(多用于地址填写), 实际应用中请预防sql注入问题

一. 实例化:

单例模式(传入过滤等级)：

$filter = DrFilter::instance(1);

新建模式(传入过滤等级):

$filter = new DrFilter(1);

二. API:

```
/**
 * 设置默认的过滤字符
 * @param array $deny
 * @return $this;
 */
function setDefaultDeny(array $deny)

/**
 * 查看默认的过滤字符
 * @return array
 */
function getDefaultDeny()

/**
 * 查看默认的过滤等级
 * @return mixed
 */
function getStrict()

/**
 * 设置过滤等级
 * @param int $strict
 * @return $this
 */
function setStrict(int $strict)

/**
 * 设置自定义正则校验
 * @param int $strict
 * @return $this
 */
function setPreg($preg)

/**
 * 安全过滤输入,支持数组
 * 1.筛选默认过滤字符
 * 2.根据过滤等级或附加正则筛选
 * @param string|array $input 输入
 * @param int $strict 过滤级别,置空则为0
 * @return array
 */
function filter($input, $strict = null)

```

示例如下:

// 过滤输入

$param = DrFilter::instance()->filter(input(''));

// 按照指定正则过滤输入(检查是否是邮箱格式)

$param = DrFilter::instance()->setGrep('/^\[a-zA-Z0-9\_-\]+@\[a-zA-Z0-9\_-\]+(.\[a-zA-Z0-9\_-\]+)+$/')->filter(input('email'));
