Question

php foreach循环的问题，一直循环两次（将两种索引都检索一遍）…………

foreach ($temp_authority as $key => $value) {
$_SESSION[$key] = $value;
echo "this is key :".$key." and this is value : ".$value." ;<br/> ";
$i++;
}

echo 是我用来进行输出验证的，然后得到了如下结果（在网页里面显示形式）：
this is key :0 and this is value : 10 ;
this is key :ID and this is value : 10 ;
this is key :1 and this is value : super ;
this is key :charactor and this is value : super ;
this is key :2 and this is value : 9 ;
this is key :check_in and this is value : 9 ;
this is key :3 and this is value : 9 ;
this is key :elder_manage and this is value : 9 ;
this is key :4 and this is value : 9 ;
this is key :charge and this is value : 9 ;
this is key :5 and this is value : 9 ;
this is key :assistant and this is value : 9 ;
this is key :6 and this is value : 9 ;
this is key :clerk_manage and this is value : 9 ;
this is key :7 and this is value : 9 ;
this is key :warehoust and this is value : 9 ;
this is key :8 and this is value : 9 ;
this is key :meals and this is value : 9 ;
this is key :9 and this is value : 9 ;
this is key :specialsevice and this is value : 9 ;
this is key :10 and this is value : 9 ;
this is key :datas and this is value : 9 ;
this is key :11 and this is value : 9 ;
this is key :room_manage and this is value : 9 ;
this is key :12 and this is value : 9 ;
this is key :system and this is value : 9 ;

因为你查询数据库返回数组时用的是返回包含关联和数字索引的数组(MYSQL_BOTH)

建议使用mysql_fetch_assoc来遍历结果集

追问

非常感谢您的回答O(∩_∩)O哈哈~

另外，请问 fetch_arry 所取回的结果集是怎样子存储的呢？ 就是像我所打印出来的那样，{0:'10' , ID:'10' , 1:'super' , charactor:'super' , ………………}这样子存储的吗？
