关于多维数组的一个问题，

<?php	$class = [		"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"]		]	];	echo '<pre class="brush:php;toolbar:false">';	print_r( $class );	echo '

回复讨论(解决方案)

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")
        )
    )) ;
