原生php遍历获取查出来的数据,进行输出
连接方法:$db=mysqli_connect("127.0.0.1","用户名","密码","数据库名")or die("Mysql连接失败" . mysqli_connect_error());
$sql="sql语句";
$res=$db->query($sql);
$str='';
foreach($res as $k => $v){
$str .=implode(',',$v) . '-';
}
$str =substr($str ,0, strlen($str) -1);
echo $str;
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
输出json格式
$arr=array();
foreach($res as $k => $v){
if($v['open']==0){
$list[$k]['id'] = $v['id'];
箭值对格式
}
$list[$k]['id'] = $v['id'];
}
$json =json_encode($list);
echo $json;
-----------------------------------------------------------------------------------------------------------------------------------
ajax返回在页面上输出
function fangru(arr){
//arrj就是查出来的数据以‘-’分割
var brr=[];
var str ="";
for(var i =0;i<arr.length;i++){
brr=arr[i].split(',');
str +='<li onclick=\" xiangqing('+brr[0]+')\">\n'+
' <div class=\"a-content\">\n' +
' <img class=\"left\" src=" '+brr[1]+' ">\n'+
' <h3 class=\"right\">\n'+
brr[3] +
' </h3>\n'+
' </div>\n'+
'<li>';
}
//然后把数据放入到html里面
$('.a-content').html(str);
}
