你好我有一个这样的字符串：

我需要从中返回一个多维数组

等等对不起，我是 php 新手，所以我不是很好，请帮助我做到这一点

另一种方式。使用预先存储的详细密钥：

<?php

// make a list of details
$details = array('world','x','y','z','yaw','pitch');
$detailkeys = array_flip( $details );
$str = "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 z: 1166.8782895110098 yaw: -0.19852135 pitch: 5.1715555 zombie: world: world x: 34.69999998807907 y: 5.0 z: 1199.704677717212 yaw: 99.74651 pitch: 8.739505 old: world: world x: -53.65626180992732 y: 73.0 z: 196.10301015333587 yaw: 116.57273 pitch: 9.224916 end3: world: world_the_end x: 286.3926594122887 y: 1.0 z: 13.586770822063027 yaw: 269.05328 pitch: 14.146775 chests: world: world x: -9.153748958043282 y: 224.0 z: 66.27320021448261 yaw: -106.30098 pitch: 39.299957 nether: world: world_nether x: -191.95650873528467 y: 49.0 z: -52.699999988079064 yaw: 22.797272 pitch: 6.7500987 endkill: world: world_the_end x: 323.4613136245915 y: 1.0 z: 5.489686192901858 yaw: 100.90347 pitch: 3.6467855 rails: world: world x: -1656.699999988079 y: 10.0 z: -283.69999998807907 yaw: 318.45834 pitch: 17.768522 blaze: world: world_nether x: -253.02856795676604 y: 53.0 z: -100.26892458131793 yaw: 91.04793 pitch: 6.150008 mine2: world: world x: -352.58729110805086 y: 72.0 z: 53.699999988079064 yaw: 27.53363 pitch: 22.949997";

$data = array();
// explode string by space
$fields = explode(' ', $str );

// go through parameters one by one
foreach( $fields as $field )
{
        // does it have colon ?
        if( preg_match('/:$/', $field ))
        {

                $field = substr( $field, 0, strlen($field)-1);
                // is it detailkey

                        $key = $field;  // store as key
                else
                        $rootkey = $field;  // otherwise store as rootkey
                continue;
        } else

        // does not have colon. Let's store a value.
        $val = $field;
        $data[$rootkey][$key] = $val;
}

// all done, echo output

var_export( $data );

编辑：

这将给出这个输出：

您可以编写一个小循环来表示存储在字符串中的数据结构，然后从中创建数组：

$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：

这是否足够，或者您是否需要额外增加所有参数（x、y、z、俯仰、偏航...）？
