A detailed example of pointers

1. Receive the contents of the URL

Public Function Newstype (Request $request)    {        $url = $request->url ();        $isfirst = input (' Isfirst ');        $uid = input (' token ');   }

　

A. To have the    nowtime inside the $news replaced with $mm ....

$news = Db::query (' Select News.nid,news.ntitle,news.nauthor,news.reviewnum,news.nowtime,news.iscollect, Newreview.ncommtent from News,newreview WHERE News.nid=newreview.nid '); foreach ($news as & $mm) {    //News comment    $ Ncommtent = Db::query ("Select Ncommtent from  newreview  where nid = {$mm [' nid ']}");    foreach ($ncommtent as $VVV) {        $mm [' ncommtent '] = "{$vvv [' ncommtent ']}";    }    $nowtime = Db::query (' Select Nowtime from  News ');    foreach ($nowtime as $n) {        $mm [' nowtime '] = Date ("y-m-d h:i:s", $n [' nowtime ']);}    }

　　

B. Append $vvv[' ncommtent] to $new

   $news = Db::query ("Select Nid,ntitle,nauthor,reviewnum, Nowtime,iscollect from  news  where nsid = ' {$ntid} ' Limit 6,6 ");                    foreach ($news as & $mm 2) {                        //News comment                        $ncommtent = db::query ("Select Ncommtent from  newreview  where nid = {$mm 2[' nid ']} ");                        foreach ($ncommtent as $VVV) {                            $mm 2[' ncommtent '] = "{$vvv [' ncommtent ']}";                        }

3. Output JSON

$data = Array (                ' code ' = = 0,                ' msg ' = +                    Array (                        ' news ' = ' $news,                        ' newsimg ' + $newsimg ,                        ' comments ' = $comments                    )            );            Return Json_encode ($data, N.);  JSON, and does not appear garbled
