public function doMobilealtermajor(){
            global $_W,$_GPC;            $_GPC[&#39;do&#39;]=&#39;altercode&#39;;            for($i=1;$i<=29083 ;$i++){                $info = M(&#39;enroll_major&#39;)->getInfo($i);                $major = $info[&#39;major&#39;];
                iconv("gbk","utf-8",$major);                $pattern = &#39;/([\x{4e00}-\x{9fa5}]+)(\[\d,\d\])/u&#39;;                $replace = &#39;$1&#39;;                $newmajor = preg_replace($pattern,$replace,$major);                $info[&#39;major&#39;] = $newmajor;
                M(&#39;enroll_major&#39;)->update($info);

            }            include $this->template(&#39;index&#39;);
    }

    public function doMobilealtername(){
        global $_W,$_GPC;        for($id=1;$id<=1225;$id++){            $info = M(&#39;enroll_science&#39;)->getInfo($id);            $pattern1 = &#39;/\w\d+([\S|\s]+)/i&#39;;            $replacement1 = &#39;$1&#39;;            $newname =  preg_replace($pattern1, $replacement1, $info[&#39;name&#39;]);            $pattern2 = &#39;/(\w\d+)([\S|\s]+)/i&#39;;            $replacement2 = &#39;$1&#39;;            $newcode =  preg_replace($pattern2, $replacement2,$info[&#39;name&#39;]);            $info[&#39;name&#39;] = $newname;            $info[&#39;zscode&#39;] = $newcode;
