Question

我有这个静态数组：

$elems = array(
  date($format, strtotime("12-12-12"))
     => array(
            "Title" => "title1",
            "Color" => "color1"),
  date($format, strtotime("12-12-11"))
     => array(
            "Title" => "title2",
            "Color" => "color2"),
);

我想变成一个动态数组（具有相同的元素）。

由于某种原因，以下代码不好：

  $elems = array();
  $elems[] = date($format, strtotime("12-12-12"))
     => array(
            "Title" => "title1",
            "Color" => "color1");
  $elems[] = date($format, strtotime("12-12-11"))
     => array(
            "Title" => "title2",
            "Color" => "color2");

为什么不好？我该如何解决？

Answer 1

你可以这样做：

$elems = array();
$elems[date($format, strtotime("12-12-12"))] = array(
        "Title" => "title1",
        "Color" => "color1");
$elems[date($format, strtotime("12-12-11"))] = array(
        "Title" => "title2",
        "Color" => "color2");

通常$array = array('key' => 'value');与$array['key'] = 'value';相同。

另请查看documentation。

Answer 2

应该是：

$elems = array();
$elems[date($format, strtotime("12-12-12"))] =  array(
    "Title" => "title1",
    "Color" => "color1"
);

将静态多维数组转换为动态数组
