PHP自动处理提交过来的表单

<php
//安全过滤
        function safe($str)
        {
            $str = trim($str);
            $str = strip_tags($str);
            //mysql_real_escape_string前提是数据库连接上了
            $str = mysql_real_escape_string($str);
            return $str;
        }        


//处理POST
        function posts($post,$array,$other)
        {
            $array = array_flip($array);
            foreach ($post as $k=>$val)
            {
                if (array_search($k,$array))
                {
                    $data[$k]    = $val; 
                }else
                {
                    $data[$k]   = $this->safe($val);
                }                
                //其它个别的处理
                !empty($other)?$data     = array_merge($data,$other):null;
            }            
            return $data;
