Php 如何从该字符串返回多维数组？
你好，我有这样一个字符串：Php 如何从该字符串返回多维数组？,php,minecraft,Php,Minecraft,你好，我有这样一个字符串： end: world: world_the_end x: 127.92422698364012 y: 49.0 z: 16.12629933731299 yaw: 181.38281 pitch: 14.804417 sand: world: world x: -1641.5 y: 71.0 z: -26.5 yaw: 90.90824 pitch: 18.818556 spider: world: world x: 31.300000011920922 y: 4.0

您可以编写一个表示存储在字符串中的数据结构的小循环，然后用它创建数组：
$string = "end: world: world_the_end x: 127.92422698364012 y: 49.0 z: ...";
$array = null;
$stack = array_reverse(explode(' ', $string));
$stackSize = count($stack);
$section = 0;
while ($stack) {
$name = substr(array_pop($stack), 0, -1); $stackSize--;
while ($stack && substr($stack[$stackSize-2], -1) !== ':') {
$key = substr(array_pop($stack), 0, -1);
$array[$name][$key] = array_pop($stack);
$stackSize -= 2;
}
}
var_dump($array);
将输出：

你的输入真的没有比这更多的结构吗？此外，您需要指定输出的外观（给出一个示例）。输入不清晰（未结构化），输出未定义。。。你尝试过什么？这是一个来自Minecraft的数据模式输出，可以匹配和分割it@ZathrusWriter是的，我想那可能是一堆游戏数据。在问题中提到这一点会很有帮助！这样标记。@从这里我为什么不考虑重新标记。。。好主意，谢谢！：）这对示例数据有效，但对动态生成的数据可能无效，因为您预先定义了所有键。。。但它应该得到+1：）现在，因为它似乎来自minecraft，我想最好预先定义较低的键，而不是较高的键。制作一个世界阵列，x，y，z，俯仰，偏航等。也许如果你玩过Minecraft，你会看到一个模式^^^^哦，你可以说，向前看一点。请看这可能是最好的答案：）编辑：添加了输出转储不幸的是，我得到的是“未定义变量：rootkey”，似乎没有触发if语句中rootkey的设置，不过感谢您的回复@user1725751如果字符串与示例中的不同，则会发生这种情况。它是不是以别的东西开始而不是结束：？
