用最新的swoole6做中大型项目会出现的问题 全部标题文字给我=信创与国产化类+AI 集成类
·
十四、信创与国产化类
132. 鲲鹏/飞腾 ARM64 二进制兼容性
病根:x86 的预编译 .so 直接放鲲鹏/飞腾跑 →illegal instruction;CRC32C/AES 指令集差异;不同厂商 ARM 微架构(鲲鹏 920
vs 飞腾 2500)调优参数不同。
# 必须源码编译,针对架构调优
# 鲲鹏 920
CFLAGS="-O3 -march=armv8-a+crc+crypto -mtune=tsv110 -fno-plt" \
LDFLAGS="-Wl,-O1 -Wl,--as-needed" \
./configure --enable-swoole --enable-openssl \
--enable-http2 --enable-mysqlnd \
--enable-swoole-coro-time
make -j$(nproc) && make install
# 飞腾 2500
CFLAGS="-O3 -march=armv8-a+crc -mtune=phytium-2500" ./configure ...
# 通用兼容版本(性能略差,跨厂商可移植)
CFLAGS="-O3 -march=armv8-a+crc" ./configure ...
// 启动自检
$arch = php_uname('m');
if ($arch === 'aarch64') {
$cpuinfo = file_get_contents('/proc/cpuinfo');
if (str_contains($cpuinfo,'tsv110')) $vendor = 'kunpeng';
elseif (str_contains($cpuinfo,'FT-')) $vendor = 'phytium';
else $vendor = 'generic_arm64';
Log::info("running on $vendor");
// 按厂商动态调参
if ($vendor==='kunpeng') Coroutine::set(['c_stack_size'=>512*1024]);
}
# Dockerfile:多架构镜像

pecl install swoole
# docker buildx build --platform linux/amd64,linux/arm64 -t myapp:v1 --push .
133. 龙芯 LoongArch 缺 JIT 后端
病根:PHP 8.x JIT 只支持 x86_64 + AArch64,LoongArch 需要关 JIT,纯 opcache 跑。
; loongarch.ini
opcache.enable=1
opcache.enable_cli=1
opcache.memory_consumption=512
opcache.max_accelerated_files=100000
opcache.validate_timestamps=0
opcache.preload=/app/preload.php
opcache.preload_user=www-data
opcache.jit=disable ; 必须关
opcache.huge_code_pages=0
# 自动检测启用对应配置
ARCH=$(uname -m)
case "$ARCH" in
x86_64|aarch64) cp /etc/php/conf.d/jit.ini /etc/php/conf.d/00-arch.ini ;;
loongarch64) cp /etc/php/conf.d/loong.ini /etc/php/conf.d/00-arch.ini ;;
*) echo "unsupported arch: $ARCH"; exit 1 ;;
esac
// 关键路径用 opcache + 手写优化代替 JIT
// 例:热函数循环展开
function hot_sum(array $a): int {
$n = count($a); $r = 0; $i = 0;
// 4-way 展开
for (; $i+4 <= $n; $i += 4) $r += $a[$i]+$a[$i+1]+$a[$i+2]+$a[$i+3];
for (; $i < $n; $i++) $r += $a[$i];
return $r;
}
// 极致:写 C 扩展或 FFI
// 龙芯生态 FFI 可用
$ffi = FFI::cdef("long fast_sum(long *arr, long n);", "libfast.so");
134. 麒麟/UOS 内核 epoll/io_uring 差异
病根:麒麟 V10 SP2 内核 4.19,没 io_uring;UOS 1050 是 5.10,有 io_uring 但版本旧;Swoole 默认探测可能错配。
# 内核能力检测
uname -r
grep -q "io_uring" /proc/kallsyms && echo "io_uring available" || echo "no io_uring"
ls /proc/sys/kernel/io_uring_* 2>/dev/null
// 启动按内核能力配置
$kernel = (float)preg_replace('/^(\d+\.\d+).*/','$1', php_uname('r'));
$ioUring = file_exists('/sys/kernel/debug/tracing/events/io_uring');
$serverConf = [
'reactor_num' => swoole_cpu_num(),
'worker_num' => swoole_cpu_num()*2,
];
if ($kernel >= 5.10 && $ioUring) {
// io_uring 加速文件 IO(Swoole 5.0+ 实验支持)
$serverConf['enable_iouring'] = true;
$serverConf['iouring_entries'] = 32768;
$serverConf['iouring_workers'] = 4;
} else {
// 麒麟 4.19:用 aio thread pool 兜底
$serverConf['aio_core_worker_num'] = 8;
$serverConf['aio_worker_num'] = 32;
$serverConf['aio_max_wait_time'] = 1.0;
}
$server->set($serverConf);
# 麒麟 4.19 epoll 调优
sysctl -w fs.epoll.max_user_watches=2097152
sysctl -w net.core.somaxconn=65535
135. 国产数据库驱动协程化缺失
病根:达梦 dpiapi、人大金仓 libpq 国产分支、GBase libgci 都是同步阻塞 C 库,没协程化封装。
// 通用方案:同步驱动连接池 + task_worker 桥接,对外暴露协程接口
class SyncDbBridge {
private Coroutine\Channel $idle; // 连接池
public function __construct(
private string $type, // dm/kingbase/gbase
private array $config,
private int $size = 50,
){
$this->idle = new Coroutine\Channel($size);
for ($i=0; $i<$size; $i++) $this->idle->push($this->newConn());
}
private function newConn() {
return match($this->type) {
'dm' => DM::connect($this->config),
'kingbase'=> pg_connect($this->buildDsn()),
'gbase' => gci_connect(...$this->configArgs()),
};
}
/** 协程 API:内部把同步调用塞 task_worker */
public function query(string $sql, array $params=[]): array {
$payload = ['driver'=>$this->type,'sql'=>$sql,'params'=>$params];
$r = server()->taskCo([$payload], 30.0);
if (!$r || !isset($r[0])) throw new \RuntimeException('db timeout');
if (isset($r[0]['error'])) throw new \RuntimeException($r[0]['error']);
return $r[0]['rows'];
}
}
// task_worker 真正执行同步驱动
$server->set(['task_worker_num'=>32,'task_enable_coroutine'=>false]);
$server->on('Task', function($s,$id,$src,$d){
static $conns = [];
$key = $d['driver'];
$conns[$key] ??= newSyncConn($d['driver']);
try {
$rows = syncQuery($conns[$key], $d['sql'], $d['params']);
return ['rows'=>$rows];
} catch(\Throwable $e) {
unset($conns[$key]); // 失败重建
return ['error'=>$e->getMessage()];
}
});
// 进阶:每个 task_worker 独占连接池,协程级负载均衡
class DriverWorkerPool {
public function dispatch(array $payload): array {
// 哈希到固定 worker,保证连接亲和性
$wid = crc32($payload['shard'] ?? '') % server()->setting['task_worker_num'];
return server()->taskCo([$payload], 30.0, $wid)[0];
}
}
136. 国密 HSM 卡 PCIe 多 worker 争用
病根:HSM 通常单卡,N 个 worker 都打开 /dev/hsm0,驱动内部锁竞争把吞吐拉到几百 QPS。
/* hsm_proxy.c ——单一进程独占 HSM,worker 走共享内存请求 */
typedef struct {
_Atomic(uint32_t) seq;
_Atomic(uint32_t) head, tail;
struct {
uint32_t worker_id;
uint32_t op; /* SM2_SIGN/SM4_ENC/... */
uint32_t in_len;
uint8_t in[4096];
uint32_t out_len;
uint8_t out[4096];
_Atomic(uint8_t) state; /* 0=空 1=请求 2=完成 */
} slots[1024];
} hsm_ring_t;
class HsmClient {
private $shm;
public function __construct(){
// 共享内存 ring buffer
$this->shm = shmop_open(0xC001, 'w', 0, 0);
}
public function sm2Sign(string $msg, string $kid): string {
$slot = $this->reserveSlot();
// 写请求
shmop_write($this->shm, pack('VVV',
getmypid(), 1 /*SM2_SIGN*/, strlen($msg)).$msg, $slot*4096);
// 等结果(协程 yield + 信号量)
return $this->waitResult($slot, 1.0);
}
}
// HSM 守护进程
class HsmDaemon {
public function run(){
$hsm = hsm_open('/dev/hsm0'); // 全局唯一打开
while (true) {
$req = $this->ring->dequeue(); // 阻塞拉
if (!$req) { usleep(100); continue; }
$out = match($req->op) {
1 => hsm_sm2_sign($hsm, $req->in, $req->kid),
2 => hsm_sm4_encrypt($hsm, $req->in, $req->key),
};
$this->ring->respond($req, $out);
}
}
}
// 独立进程启动:systemctl start hsm-daemon
// 简化版:worker 0 独占 HSM,其他 worker 通过 sendMessage 转发
$server->on('PipeMessage', function($s,$src,$msg){
if ($s->worker_id !== 0) return;
$req = json_decode($msg, true);
$sig = hsm_sm2_sign($req['msg'], $req['kid']);
$s->sendMessage(json_encode(['rid'=>$req['rid'],'sig'=>$sig]), $src);
});
137. OpenEuler 调度器 ×Reactor 亲和
病根:OpenEuler 默认 CFS 调度,Swoole Reactor 线程经常被抢占到不同核,缓存抖动;多虚拟机超线程拓扑识别不准。
# 1) 开启高性能调度器(OpenEuler 22.03 SP3+)
sysctl -w kernel.sched_autogroup_enabled=0 # 关 autogroup
sysctl -w kernel.sched_migration_cost_ns=5000000
# 2) 锁定 CPU 频率
cpupower frequency-set -g performance
# 3) 隔离核(启动参数)
# /etc/grub.d/40_custom 加入:
# isolcpus=8-15 nohz_full=8-15 rcu_nocbs=8-15
// 程序内绑核 + IRQ 亲和
class CoreAffinity {
public static function bindReactor(int $reactorIdx){
$cpu = 8 + $reactorIdx; // 用隔离核 8-15
$set = [$cpu];
swoole_set_cpu_affinity($set);
// 也调高优先级
proc_nice(-10);
}
}
$server->on('ManagerStart', function($s){
// 拓扑:reactor 绑隔离核,worker 绑普通核
});
// 配合 IRQ 平衡
// echo 0,1,2,3 > /proc/irq/网卡IRQ/smp_affinity_list
# OpenEuler 特有:开 A-Tune 智能调优
atune-adm tuning --project web_server --start
138. 国产 AI 芯片 SDK 阻塞协程
病根:寒武纪 cnrt、昇腾 ACL 都是同步阻塞 C API,跑推理时整个协程线程被卡。
class NpuRunner {
/** 推理走专属 worker 池,避免阻塞 reactor */
public function infer(string $modelId, array $tensorData): array {
$payload = ['model'=>$modelId,'data'=>$tensorData];
// 哈希到固定 worker,模型预加载亲和
$wid = crc32($modelId) % $this->npuWorkerNum();
$r = server()->taskCo([$payload], 5.0, $wid);
return $r[0];
}
}
// task_worker 启动时预加载模型
$server->set([
'task_worker_num' => 8, // 等于 NPU 卡数
'task_enable_coroutine' => false, // 同步驱动不开协程
]);
$server->on('WorkerStart', function($s,$wid){
if ($s->taskworker) {
// 寒武纪:每 task_worker 绑一张 MLU 卡
$card = $wid - $s->setting['worker_num'];
cnrtSetDevice($card);
ModelCache::preload($card);
}
});
$server->on('Task', function($s,$id,$src,$d){
$model = ModelCache::get($d['model']);
return $model->infer($d['data']);
});
/* 进阶:FFI + 异步 NPU 队列 */
// 寒武纪 cnrtQueue 可异步提交
cnrtQueue_t q;
cnrtQueueCreate(&q);
cnrtMemcpyAsync(dev_ptr, host_ptr, n, q, CNRT_MEM_TRANS_DIR_HOST2DEV);
cnrtInvokeRuntimeContext_V2(ctx, params, q, NULL);
cnrtMemcpyAsync(host_out, dev_out, m, q, CNRT_MEM_TRANS_DIR_DEV2HOST);
// 协程侧 yield 等 cnrtQueueSync 完成(用 eventfd 桥接到 epoll)
139. 信创办 SBOM 合规
病根:信创软件供应链要求每个组件可追溯(NTIA SBOM 标准),Swoole + 一堆 PECL 扩展 + composer 包 + 系统库,源头不清。
# 生成 SBOM(SPDX 格式)
# PHP 扩展层
syft scan dir:/usr/lib/php/modules -o spdx-json > sbom-php-ext.json

// 程序内自描述 SBOM
class SBOMReport {
public static function generate(): array {
return [

'version' => env('APP_VERSION'),
'components' => [
['name'=>'php','version'=>PHP_VERSION,'license'=>'PHP-3.01'],

...self::scanComposer(),
...self::scanExtensions(),
],
'sha256' => hash_file('sha256', PHP_BINARY),
];
}
}
140. 等保三级测评 PHP+Swoole 整改项
病根:等保三级 8 大控制要求里,PHP+Swoole 在身份鉴别、访问控制、安全审计、可信验证 4 项最容易踩雷。
class L3Compliance {
/** 8.1.4.1 身份鉴别:双因素 + 强密码 */
public static function authVerify(string $user, string $pwd, string $otp): bool {
if (strlen($pwd) < 12) return false;
if (!preg_match('/[A-Z]/',$pwd)) return false;
if (!preg_match('/[a-z]/',$pwd)) return false;
if (!preg_match('/[0-9]/',$pwd)) return false;
if (!preg_match('/[^A-Za-z0-9]/',$pwd)) return false;
if (!password_verify($pwd, UserStore::hash($user))) return false;
// 第二因素 TOTP
return totp_verify(UserStore::otpSecret($user), $otp);
}
/** 8.1.4.2 访问控制:RBAC + 最小权限 */
public static function checkAccess(int $uid, string $resource, string $action): bool {
$roles = RbacStore::userRoles($uid);
foreach ($roles as $role) {
if (RbacStore::can($role, $resource, $action)) return true;
}
AuditLog::write(['event'=>'access_denied','uid'=>$uid,'res'=>$resource]);
return false;
}
/** 8.1.4.3 安全审计:不可篡改 + 集中存储 */
public static function auditLog(array $rec){
// 国密 SM3 链式哈希
static $prevHash = '';
$rec['prev_hash'] = $prevHash;
$rec['ts_ns'] = hrtime(true);
$rec['nonce'] = bin2hex(random_bytes(16));
$hash = hash('sm3', json_encode($rec));
$prevHash = $hash;
// 落盘 + 同步到独立审计服务器
AuditChannel::push(json_encode($rec + ['hash'=>$hash]));
}
/** 8.1.4.6 可信验证:启动时校验关键文件 */
public static function trustedBoot(): bool {
$manifest = json_decode(file_get_contents('/etc/app/trusted.json'), true);
foreach ($manifest['files'] as $path => $expected) {
if (hash_file('sm3', $path) !== $expected) {
Log::critical("trust violation: $path");
return false;
}
}
return true;
}
}
// 启动入口
if (!L3Compliance::trustedBoot()) exit(1);
$server->on('request', function($req,$resp){
SafeGo::go(function() use($req,$resp){
if (!L3Compliance::authVerify(...)) abort(401);

十五、AI 集成类
141. 大模型推理阻塞 Reactor
病根:直接 cURL 调本地/远端 LLM,几秒到几十秒返回,把协程占着不放,堆积。
class LlmClient {
/** 用 cURL hook 后协程化的 stream,不阻塞 reactor */
public function chat(string $prompt, float $timeout=60.0): string {
$cli = new Coroutine\Http\Client('llm.local', 8000);
$cli->setHeaders(['Content-Type'=>'application/json']);
$cli->set(['timeout'=>$timeout]);
$cli->post('/v1/chat', json_encode([
'model'=>'qwen2-72b',
'messages'=>[['role'=>'user','content'=>$prompt]],
'stream'=>false,
]));
$body = $cli->getBody();
$cli->close();
return json_decode($body, true)['choices'][0]['message']['content'];
}
/** 长任务隔离到专属 worker 池,避免占用业务协程 */
public function chatAsync(string $prompt): int {
$taskId = bin2hex(random_bytes(8));
server()->task(['type'=>'llm','prompt'=>$prompt,'tid'=>$taskId]);
return $taskId;
}
}
// 限流 + 排队(防 LLM 过载)
class LlmGateway {
private Coroutine\Channel $sem;
public function __construct(int $maxConcurrent=64){
$this->sem = new Coroutine\Channel($maxConcurrent);
for ($i=0;$i<$maxConcurrent;$i++) $this->sem->push(1);
}
public function call(callable $fn, float $timeout=60){
if (!$this->sem->pop(1.0)) throw new \RuntimeException('llm overload');
try { return $fn(); }
finally { $this->sem->push(1); }
}
}
142. 流式响应背压
病根:LLM 流式输出比客户端消费快,发送缓冲爆炸。
class StreamingChat {
public function handle(Swoole\Http\Request $req, Swoole\Http\Response $resp){
$resp->header('Content-Type','text/event-stream');
$resp->header('Cache-Control','no-cache');
$resp->header('X-Accel-Buffering','no');
$cli = new Coroutine\Http\Client('llm.local', 8000);
$cli->set(['timeout'=>-1]);
$cli->setHeaders(['Content-Type'=>'application/json']);
$cli->setMethod('POST');
$cli->setData(json_encode([
'prompt'=>$req->post['prompt'],
'stream'=>true,
]));
$cli->execute('/v1/chat');
while ($chunk = $cli->recv()) {
// 关键:write 失败说明客户端慢/断
if ($resp->write("data: $chunk\n\n") === false) {
Log::warn('client slow/disconnected, abort llm');
break; // 主动断开 LLM 请求
}
// 监控发送缓冲,超阈值 sleep 让出
$info = $resp->socket->getsockopt(SOL_SOCKET, SO_NWRITE) ?? 0;
if ($info > 1024*1024) Coroutine::sleep(0.01);
}
$cli->close();
$resp->end();
}
}
// WebSocket 流式:用 Swoole buffer watermark
$server->set([
'send_yield' => true,
'buffer_high_watermark' => 4*1024*1024,
'buffer_low_watermark' => 1*1024*1024,
]);
$server->on('BufferFull', fn($s,$fd)=> Log::warn("ws $fd back pressure"));
143. 张量序列化协程零拷贝
病根:tensor 数据几 MB 一个,json_encode 把 zval 全拷一遍,内存翻倍。
class TensorMessage {
/** 用二进制 + 共享内存避免拷贝 */
public function pack(array $tensor, string $dtype, array $shape): string {
// 头:dtype(8B) + rank(4B) + shape(rank*4B) + length(4B)
$hdr = str_pad($dtype, 8, "\0").pack('V', count($shape));
foreach ($shape as $d) $hdr .= pack('V',$d);
// body:直接 pack 二进制(FFI/SplFixedArray 更省)
$bin = pack('f*', ...$tensor);
$hdr .= pack('V', strlen($bin));
return $hdr.$bin;
}
public function unpack(string $raw): array {
$dtype = trim(substr($raw,0,8),"\0");
$rank = unpack('V', substr($raw,8,4))[1];
$shape = array_values(unpack('V*', substr($raw,12,$rank*4)));
$len = unpack('V', substr($raw,12+$rank*4,4))[1];
$bin = substr($raw, 16+$rank*4, $len);
return ['dtype'=>$dtype,'shape'=>$shape,'data'=>$bin];
}
}
// 协程间传递只传句柄,不传数据
class TensorRegistry {
private static array $store = [];
public static function put(string $bin): string {
$id = bin2hex(random_bytes(8));
self::$store[$id] = $bin;
return $id;
}
public static function take(string $id): string {
$b = self::$store[$id] ?? '';
unset(self::$store[$id]);
return $b;
}
}
// channel 只 push id
$ch->push(TensorRegistry::put($binTensor));
// 消费侧
$bin = TensorRegistry::take($ch->pop());
144. ONNX Runtime 线程模型冲突
病根:ONNX Runtime 内部用 OpenMP/线程池,与 Swoole 协程线程并存时争 CPU,性能反而下降。
class OnnxSession {
public function __construct(string $modelPath, int $intraThreads=1, int $interThreads=1){
$opts = OnnxRuntime::sessionOptions();
// 关键:限制 ORT 内部线程,让 Swoole worker 控制并发
$opts->setIntraOpNumThreads($intraThreads); // 单算子内部线程
$opts->setInterOpNumThreads($interThreads); // 算子间并行
$opts->setExecutionMode('sequential');
$opts->setGraphOptimizationLevel('all');
$this->session = new OnnxSession($modelPath, $opts);
}
}
// 配合 task_worker:每 worker 1 个会话,单线程
$server->set([
'task_worker_num' => swoole_cpu_num(), // = 物理核
'task_enable_coroutine' => false,
]);
$server->on('WorkerStart', function($s,$wid){
if ($s->taskworker) {
$core = $wid - $s->setting['worker_num'];
// 绑核
swoole_set_cpu_affinity([$core]);
// 每个 task_worker 1 个 ORT 会话,单线程跑(避免线程池争用)
$GLOBALS['ort'] = new OnnxSession('/models/m.onnx', 1, 1);
}
});
$server->on('Task', function($s,$id,$src,$d){
return $GLOBALS['ort']->run($d['inputs']);
});
145. GPU/NPU 显存生命周期 ×zval
病根:PHP 的 zval refcount 管不到显存;zval 释放时显存没释放→OOM;提前释放→野指针。
/* gpu_zval.c ——自定义资源类型 */
#include "Zend/zend_API.h"
typedef struct {
void *dev_ptr; // GPU/NPU 显存指针
size_t bytes;
int device_id;
int (*free_fn)(void*); // cudaFree / cnrtFree / aclrtFree
} gpu_buf_t;
static int le_gpu_buf;
static void gpu_buf_dtor(zend_resource *res) {
gpu_buf_t *b = (gpu_buf_t*)res->ptr;
if (b->dev_ptr) b->free_fn(b->dev_ptr);
efree(b);
}
PHP_FUNCTION(gpu_alloc) {
zend_long bytes;
ZEND_PARSE_PARAMETERS_START(1,1) Z_PARAM_LONG(bytes) ZEND_PARSE_PARAMETERS_END();
gpu_buf_t *b = emalloc(sizeof(*b));
cudaMalloc(&b->dev_ptr, bytes);
b->bytes = bytes; b->free_fn = cudaFree;
RETURN_RES(zend_register_resource(b, le_gpu_buf));
}
// PHP_MINIT 注册:le_gpu_buf = zend_register_list_destructors_ex(gpu_buf_dtor,...);
// PHP 用法
$buf = gpu_alloc(1024 * 1024 * 100); // 100MB 显存
gpu_memcpy_h2d($buf, $hostData);
$out = onnx_run_gpu($buf);
unset($buf); // 自动 free,refcount 安全
// 协程间共享:用 WeakReference 避免循环引用
class GpuTensor {
public $resource;
public function __destruct(){ /* gpu_buf_dtor 自动调 */ }
}
go(function() use($tensor){
$weak = WeakReference::create($tensor);
Coroutine::sleep(1);
if ($t = $weak->get()) infer($t); // 主流程已释放则跳过
});
146. AI 批处理 batching 协调
病根:单条推理 NPU 利用率低,要 batching;但协程异步触发时机不齐,攒不够 batch 又不能等太久。
class DynamicBatcher {
private Coroutine\Channel $reqCh;
private array $waiters = []; // tid => Channel(响应)
public function __construct(
private int $maxBatch = 32,
private float $maxWaitMs = 10, // 最多等 10ms
){
$this->reqCh = new Coroutine\Channel(1024);
Coroutine::create(fn()=> $this->loop());
}
public function infer(array $input): array {
$tid = bin2hex(random_bytes(8));
$resp = new Coroutine\Channel(1);
$this->waiters[$tid] = $resp;
$this->reqCh->push(['tid'=>$tid,'input'=>$input]);
$r = $resp->pop(30);
unset($this->waiters[$tid]);
return $r;
}
private function loop(){
while (true) {
$batch = []; $deadline = microtime(true) + $this->maxWaitMs/1000;
// 收集到 maxBatch 或超时
while (count($batch) < $this->maxBatch && microtime(true) < $deadline) {
$rem = max(0, $deadline - microtime(true));
$req = $this->reqCh->pop($rem);
if ($req === false) break;
$batch[] = $req;
}
if (!$batch) continue;
// 拼成 batch 推理
$inputs = array_column($batch,'input');
$outputs = NpuRunner::batchInfer($inputs);

147. Continuous Batching 在 PHP 盲区
病根:vLLM/TensorRT-LLM 这类引擎已实现 continuous batching(动态拼接不同长度请求),PHP 侧没法控制 KV cache。
// PHP 侧不实现 continuous batching,转发到专业推理服务
class ContinuousBatchClient {
/** 用 gRPC 流式接 vLLM/TensorRT-LLM */
public function generateStream(string $prompt, callable $onToken){
$cli = new Coroutine\Http2\Client('vllm.local', 8001);
$cli->set(['timeout'=>-1]);
$cli->connect();
$req = new Swoole\Http2\Request;
$req->method = 'POST';
$req->path = '/v2/models/llama/generate_stream';
$req->headers = ['content-type'=>'application/json'];
$req->data = json_encode([
'inputs'=>$prompt,
'parameters'=>['max_new_tokens'=>512,'streaming'=>true]
]);
$req->pipeline = true;
$sid = $cli->send($req);
while ($resp = $cli->recv(-1)) {
$token = json_decode($resp->data, true)['token']['text'] ?? '';
if ($token === '') continue;
if ($onToken($token) === false) break;
if ($resp->pipeline_id == 0) break;
}
$cli->close();
}
}
// 业务层
$cb = new ContinuousBatchClient;
$cb->generateStream($prompt, function($tok) use($resp){
return $resp->write("data: $tok\n\n") !== false; // 客户端断开返回 false
});

148. 向量数据库连接池协程绑定
病根:Milvus/PGVector 客户端有自己的连接管理,协程 yield 后连接归属错乱;查询返回大向量内存爆。

// PGVector 走 PDO,注意类型

大白话总结
- 信创国产化(132-140):核心是"按架构源码编译 + 内核能力探测开关 io_uring + 同步驱动通过 task_worker 桥接成协程友好 +
HSM/NPU 用专属 worker 池避免争用 + SBOM 全链路扫描 + 等保三级 4
大整改项落地到代码"。这一套做齐才能真正过信创入场和等保测评。
- AI 集成(141-148):核心是"长任务必走专属 worker 池或限流 channel,不阻塞 reactor + 流式背压用 send_yield + write
返回值检测 + 张量传句柄不传数据 + ONNX/NPU SDK 单线程化绑核避免线程池争用 + GPU 显存挂自定义 zval 资源类型 + Dynamic
Batching 攒批 + Continuous Batching 直接转发 vLLM"。这套做完,PHP 也能稳跑大模型推理网关、向量检索、信创 AI 服务。
把这两层固化进基础设施,业务侧只剩"接 API + 写 prompt + 落库"三件事,所有信创和 AI 的坑都被兜住。
