如何创建复杂的多维关联数组？

// 创建一个多维关联数组
var multiDimensionalArray = {
  key1: [1, 2, 3],
  key2: {
    subKey1: 'value1',
    subKey2: 'value2'
  },
  key3: [
    { subKey: 'value3' },
    { subKey: 'value4' }
  ]
};

// 访问多维关联数组的值
console.log(multiDimensionalArray.key1); // 输出: [1, 2, 3]
console.log(multiDimensionalArray.key2.subKey1); // 输出: value1
console.log(multiDimensionalArray.key3[0].subKey); // 输出: value3

# 创建一个多维关联数组
multi_dimensional_array = {
  'key1': [1, 2, 3],
  'key2': {
    'subKey1': 'value1',
    'subKey2': 'value2'
  },
  'key3': [
    {'subKey': 'value3'},
    {'subKey': 'value4'}
  ]
}

# 访问多维关联数组的值
print(multi_dimensional_array['key1'])  # 输出: [1, 2, 3]
print(multi_dimensional_array['key2']['subKey1'])  # 输出: value1
print(multi_dimensional_array['key3'][0]['subKey'])  # 输出: value3

// 创建一个多维关联数组
$multiDimensionalArray = array(
  'key1' => array(1, 2, 3),
  'key2' => array(
    'subKey1' => 'value1',
    'subKey2' => 'value2'
  ),
  'key3' => array(
    array('subKey' => 'value3'),
    array('subKey' => 'value4')
  )
);

// 访问多维关联数组的值
print_r($multiDimensionalArray['key1']);  // 输出: Array ( [0] => 1 [1] => 2 [2] => 3 )
echo $multiDimensionalArray['key2']['subKey1'];  // 输出: value1
echo $multiDimensionalArray['key3'][0]['subKey'];  // 输出: value3
