public function doMobilealtermajor(){
            global $_W,$_GPC;            $_GPC['do']='altercode';            for($i=1;$i<=29083 ;$i++){                $info = M('enroll_major')->getInfo($i);                $major = $info['major'];
                iconv("gbk","utf-8",$major);                $pattern = '/([\x{4e00}-\x{9fa5}]+)(\[\d,\d\])/u';                $replace = '$1';                $newmajor = preg_replace($pattern,$replace,$major);                $info['major'] = $newmajor;
                M('enroll_major')->update($info);

            }            include $this->template('index');
    }

    public function doMobilealtername(){
        global $_W,$_GPC;        for($id=1;$id<=1225;$id++){            $info = M('enroll_science')->getInfo($id);            $pattern1 = '/\w\d+([\S|\s]+)/i';            $replacement1 = '$1';            $newname =  preg_replace($pattern1, $replacement1, $info['name']);            $pattern2 = '/(\w\d+)([\S|\s]+)/i';            $replacement2 = '$1';            $newcode =  preg_replace($pattern2, $replacement2,$info['name']);            $info['name'] = $newname;            $info['zscode'] = $newcode;

            M('enroll_science')->update($info);
