按值对数组排序

丹尼尔·史洛莫（Daniel Shlomo）

我有这个数组：

array(
 "tour_0" => 1446,
 "tour_1" => 1471,
 "date-from-1471" => "2014-08-07",
 "date-to-1471" => "2014-08-15",
 "tour_2" => 30,
 "date-from-30" => 2014-08-01,
 "date-to-30" => 2014-08-05,
 "tour_3" => 10
)

现在，我需要将其分类为：

array(
 "0" => array("ID" => 1446),
 "1" => array("ID" => 1471, "from" => "2014-08-07", "to" => "2014-08-15"),
 "2" => array("ID" => 30, "from" => "2014-08-07", "to" => "2014-08-15"),
 "3" => array("ID" => 10),
)

我该如何完成这件事？我已经尝试过各种方法，但是我似乎无法弄清楚……

感谢和抱歉的标题，但我只是不知道如何形容它。

这个怎么样？

$ret = [];
foreach($inputArray as $key => $value) {
  if (preg_match('/^tour_([0-9]+)/', $key)) {
    $ret[$value] = ["ID" => $value];
  }

  if (preg_match('/date-from-([0-9]+)/', $key, $matches)) {
    $ret[$matches[1]]["from"] = $value;
  }

  if (preg_match('/date-to-([0-9]+)/', $key, $matches)) {
    $ret[$matches[1]]["to"] = $value;
  } 
}

print_r($ret);
