推荐答案
您还可以通过指定数组的索引来创建关联数组或类似哈希表"的数组.
You can also create an associative array, or a "hash-table" like array, by specifying the index of the array.
$array = array(
0 => array(
'name' => 'John Doe',
'email' => 'john@example.com'
),
1 => array(
'name' => 'Jane Doe',
'email' => 'jane@example.com'
),
);
等同于
$array = array();
$array[0] = array();
$array[0]['name'] = 'John Doe';
$array[0]['email'] = 'john@example.com';
$array[1] = array();
$array[1]['name'] = 'Jane Doe';
$array[1]['email'] = 'jane@example.com';
