这可以通过创建缓存文件来实现。
此解决方案使用产品名称作为每个条目的键，创建一个包含API结果的文件cache.json。
在后续调用中，它将使用该高速缓存值（如果存在）。

set_time_limit(500);

function file_put_json($file, $data)

    $json = json_encode($data, JSON_PRETTY_PRINT);

        } else {
            $array[] = array_map('trim', $row);
        }
    }
    fclose($handle);
    return $array;
}

"你需要知道时间的流逝"
首先确定curl请求中的时间位置。
我猜是API响应时间。
如果是这样的话，我有一个解决方案。同时，我将得到“多任务”代码代码，我用它来做同时curl请求。
curl具有您需要的定时。它看起来像这样：

'total_time' => 0.029867,
  'namelookup_time' => 0.000864,
  'connect_time' => 0.001659,
  'pretransfer_time' => 0.00988,
  'size_upload' => 0.0,
  'size_download' => 8300.0,
  'speed_download' => 277898.0,
  'speed_upload' => 0.0,

只需添加几行代码

$response = curl_exec($curl);
$info = var_export(curl_getinfo($curl),true);
file_put_contents('timing.txt',$info,FILE_APPEND);

同时运行curl套接字。

把你的卷发放到curl.php里

$text = $_GET['text'];
  curl_setopt_array($curl, [
        CURLOPT_URL => "https://text-sentiment.p.rapidapi.com/analyze",
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_FOLLOWLOCATION => true,
        CURLOPT_ENCODING => "",
        CURLOPT_MAXREDIRS => 10,
        CURLOPT_TIMEOUT => 30,
        CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
        CURLOPT_CUSTOMREQUEST => "POST",
        CURLOPT_POSTFIELDS => $text,
        CURLOPT_HTTPHEADER => [
            "X-RapidAPI-Host: text-sentiment.p.rapidapi.com",
            "X-RapidAPI-Key: <snip>",
            "content-type: application/x-www-form-urlencoded"
        ],
    ]);

这段代码进入CSV循环，创建所有URL查询字段并传递给curl.php（例如http://127.0.0.1/curl.php?text=$text）

$query = urlencode($text);
$urls[] = array('host' => "127.0.0.1",'path' => "/curl.php?text=$query

然后处理所有URL。

foreach($urls as $path){
    $host = $path['host'];
    $path = $path['path'];
    $http = "GET $path HTTP/1.0\r\nHost: $host\r\n\r\n";
    $stream = stream_socket_client("$host:80", $errno,$errstr, 120,STREAM_CLIENT_ASYNC_CONNECT|STREAM_CLIENT_CONNECT); 
    if ($stream) {
      $sockets[] = $stream;  // supports multiple sockets
      fwrite($stream, $http);
    }
    else { 
      $err .=  "$id Failed<br>\n";
    }
  }

然后监视套接字并检索每个套接字的响应。
然后关闭插座，直到您拥有所有这些。

while (count($sockets)) {
  $read = $sockets; 
  stream_select($read, $write = NULL, $except = NULL, $timeout);
  if (count($read)) {
    foreach ($read as $r) { 
      $id = array_search($r, $sockets); 
      $data = fread($r, $buffer_size); 
      if (strlen($data) == 0) { 
     //   echo "$id Closed: " . date('h:i:s') . "\n\n\n";
        $closed[$id] = microtime(true);
        fclose($r); 
        unset($sockets[$id]);
      } 
      else {
        $results[$id] .= $data; 
      }
    }
  }
  else { 
 //   echo 'Timeout: ' . date('h:i:s') . "\n\n\n";
    break;
  }
}

所有结果都以$results[]为单位。
