php内写mysql接收资料
while($row = mysql_fetch_array($result)){
$temp[] = $row;
}
echo json_encode($temp);
出现的会是
[{"id":"1","classify":"18","mes":"good","name":"mary"},
] 全部的数据
另一个数据
没有出现?
{"id":"3","classify":"20","mes":"bad","name":"candy"}
若我只想要他出现
id 和 classify请问我要怎么写
$temp[] = $row; 这位置
PS:若写
$temp[] = $row[classify];
就可以出现两个数据的classify个别出来
如["18","20"]
所以请问想要他出现
[{"id":"1","classify":"18" },[{"id":"3","classify":"20" }]
要怎么写呢？感谢
