不能使数组发挥作用

首先为我的英语道歉函数

1. 上传文本文件，每一行都将成为数组

   中的元素

   $fh = fopen("upload/".'1.txt','r');
   $conn = array();
   while ($line = fgets($fh)) {
       $conn[] = $line;
   }
   fclose($fh);
   $wbs->SendBulk($conn, "hello world");
   

2. Go To Function

   public function SendBulk($targets, $message)
   {
       echo "Sending " . count($targets) . " bulk messages...<br />";
       foreach($targets as $target)
       {
           $this->wa->sendPresenceSubscription($target);
           $this->wa->pollMessages();
           $this->wa->sendMessageComposing($target);
           sleep(55);
           $this->wa->pollMessages();
           $this->wa->sendMessagePaused($target);
           static::$sendLock = true;
           echo "Sending message from " . $this->username . " to $target... ";
           $this->wa->sendMessage($target, $message); // Orginal
           while(static::$sendLock)
           {
               //wait for server receipt
               sleep(55);
           }
       }
   

我的问题如果我有在文本文件2或更多的元素在数组将为最后一个元素发送消息吗但是如果我创建这样的数组

$conn= array("565684898", "484849815", "484897987", "515498798");

它适用于所有元素请帮助
