Question

PHP中的多维数组 代码显示错误了

$families = Array
(
[Griffin] => Array
(
[0] => Peter
[1] => Lois
[2] => Megan
)
[Quagmire] => Array
(
[0] => Glenn
)
[Brown] => Array
(
[0] => Cleveland
[1] => Loretta
[2] => Junior
)
)

里面那里错了
echo "Is " . $families['Griffin'][2] .
" a part of the Griffin family?";

Answer 1

数组元素之间的逗号呢？
字符串加上引号
键不需要[]
$families = Array
(
'Griffin' => Array
(
0 => 'Peter',
1 => 'Lois',
2 => 'Megan'
),
'Quagmire' => Array
(
0 => 'Glenn'
),
'Brown' => Array
(
0 => 'Cleveland',
1 => 'Loretta',
2 => 'Junior'
)
)

Answer 2

你的代码不会报错吗？修改如下
<?php
$families = Array(
Griffin => Array("0" => Peter,"1" =>Lois, "2" =>Megan),
Quagmire => Array("0"=>Glenn),
Brown => Array("0" => Cleveland,"1" => Loretta,"2" => Junior)
);
?>
