我有一个我想重组的阵列。我想轮流分组。我可以弄清楚如何使用foreach($arr['history'] as $obj)
从数组中提取数据我的问题是使用循环填充新数组。
目前它看起来像这样:
Array (
[history] => Array (
[id] => 23452435
[legend] => Array (
[0] => Array (
[player] => me
[turn] => 1
[card] => Array (
[name] => foo
)
)
[1] => Array (
[player] => me
[turn] => 1
[card] => Array (
[name] => bar
)
)
[2] => Array (
[player] => opponent
[turn] => 1
[card] => Array (
[name] => derp
)
)
[3] => Array (
[player] => opponent
[turn] => 2
[card] => Array (
[name] => hoo
)
)
)
))
我希望它看起来如下,但我无法弄清楚如何自动创建和填充此结构。这是一个数组,每个回合都有一个子数组,包含一个数组给我和对手
Array (
[0] => Array (
[me] => Array (
[0] => foo
[1] => bar
)
[opponent] = Array (
[0] => derp
)
)
[1] => Array (
[me] => Array ()
[opponent] => Array (
[0] => hoo
)
))
感谢。

这就是我需要的。谢谢你的回答。
$result = [];
foreach ($arr['history'] as $historyItem) {
foreach ($historyItem['legend'] as $list) {
$result[$list['turn']][$list['player']][] = $list['card']['name'];
}
}

试试这个:
$result = [];
foreach ($data['history']['legend'] as $list) {
$result[$list['turn']-1][$list['player']][] = $list['card']['name'];
}

您可以开始向新阵列添加数据。 PHP非常宽容。
$historyByTurns = array();
foreach ($arr['history'] as $historyItem) {
foreach ($historyItem['legend'] as $legendItem) {
$turn = $legendItem['turn'];
$player = $legendItem['player'];
if (!array_key_exists($turn, $historyByTurns)) {
$historyByTurns[$turn] = array();
}
if (!array_key_exists($player, $historyByTurns[$turn])) {
$historyByTurns[$turn][$player] = array();
}
foreach ($legendItem as $card) {
$historyByTurns[$turn][$player][] = $card['name'];
}
}
}
你必须测试它,因为我无法使用那台ATM。
