使用PHP创建具有相同键的关联数组的数组

// 创建一个空数组
$array = array();

// 创建关联数组1
$array1 = array(
    'key1' => 'value1',
    'key2' => 'value2',
    'key3' => 'value3'
);

// 创建关联数组2
$array2 = array(
    'key1' => 'value4',
    'key2' => 'value5',
    'key3' => 'value6'
);

// 将关联数组1和关联数组2添加到空数组中
$array[] = $array1;
$array[] = $array2;

// 打印输出数组
print_r($array);

Array
(
    [0] => Array
        (
            [key1] => value1
            [key2] => value2
            [key3] => value3
        )

    [1] => Array
        (
            [key1] => value4
            [key2] => value5
            [key3] => value6
        )
