基于 PHP Fiber（纤程）的游戏开发分析-腾讯云开发者社区-腾讯云PHP 8.1 引入的 Fibers 为游戏开发带来新机遇，能管理渲染、物理计算等任务且不阻塞主线程。它支持并发，提升效率，简单易用，但也有局限，如单线程本质、上下文切换开销、调试复杂及生态系统不成熟。https://cloud.tencent.com/developer/article/2509749说明

• 多个用户参与游戏
• 每个人猜各自的最终数字
• 每人做多猜五次

代码：

function getroundnum() {$num = rand(0, 30);return $num;
}
class Persion {public function __construct(public string $name) {}
}
class GuessNum extends Persion {private int $resultnum;public bool $result;private int $num;private int $type;public function __construct(public string $name, public int $gap = 1) {$this->num = getroundnum();$this->resultnum = getroundnum();$this->result = false;}//type 1加数字 2减数字private function getnextnum() {if ($this->num === 0) {return $this->num;}$this->num = match ($this->type) {1 => $this->num + $this->gap,2 => $this->num - $this->gap,};}public function doguessonce() {var_dump("resultnum:" . $this->resultnum . " name:" . $this->name . " num:" . $this->num);$result = false;$this->type = 0;match (true) {$this->num == $this->resultnum => $result = true,$this->num > $this->resultnum => $this->type = 2, //减$this->num < $this->resultnum => $this->type = 1//加};$this->result = $result;if (!$result) {$this->getnextnum();}}
}

$persion_list = [new GuessNum("test1", 1),new GuessNum("npc", 2),
];$fibers = [];foreach ($persion_list as $entity) {$fibers[] = new Fiber(function () use ($entity) {while (true) {$entity->doguessonce($entity);Fiber::suspend($entity);}});
}// Start all fibers
$endresult = false;
foreach ($fibers as $fiber) {$value = $fiber->start();if ($value->result) {$endresult = true;var_dump("game end success name:" . $value->name);break;}
}
if (!$endresult) {for ($i = 0; $i < 5; $i++) {foreach ($fibers as $fiber) {$value = $fiber->resume();if ($value->result) {$endresult = true;var_dump("game end success name:" . $value->name);break;}}sleep(1);var_dump("once end");}
}
var_dump("game end ~");
