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：
