```php
<?php
set_time_limit(30);
ignore_user_abort(false);
header("Content-Length: 0");
header("Connection: Close");
echo str_pad('', ini_get('output_buffering'));
ob_end_flush();
ob_flush();
flush();
//耗时任务
sleep(10);
file_put_contents('test.log', date('Y-m-d H:i:s'), FILE_APPEND);
```
```php
<?php
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, 'http://127.0.0.1/async.php');
curl_setopt($curl, CURLOPT_HEADER, 0);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_exec($curl);
curl_close($curl);
echo '结束了';
```
有局限性，最好还是用队列吧
