关于多维数组的一个问题，

Question

php多维数组

Answer 1

你这个定义 的是什么？数组吗？ 按你的思路应该这样定义。$class =array(  "group1" => (
            ("name"=>"zs","age"=>"10","sex"=>"nan"),
            ("name"=>"ls","age"=>"11","sex"=>"nan"),
           ("name"=>"ww","age"=>"12","sex"=>"nv")
        ), 
         (
            ("name"=>"zs","age"=>"10","sex"=>"nan"),
            ("name"=>"ls","age"=>"11","sex"=>"nan"),
           ("name"=>"ww","age"=>"12","sex"=>"nv")
        ), 
        (
            ("name"=>"zs","age"=>"10","sex"=>"nan"),
            ("name"=>"ls","age"=>"11","sex"=>"nan"),
            ("name"=>"ww","age"=>"12","sex"=>"nv")
        )
    )) ;

都可以，但用[]也是这样的
$class['group1'][]=array("name"=>"zs","age"=>"10","sex"=>"nan");
$class['group1'][]=array("name"=>"ls","age"=>"11","sex"=>"nan");
$class['group1'][]=array("name"=>"ww","age"=>"12","sex"=>"nv");
