此代码用于捕获字节并将其传输到服务器。现在这是接受字节的 PHP 代码。

<?php
  if(isset($_POST['id'])) {
    $data = $_POST['id'];
    file_put_contents('cololl.txt',$data, FILE_APPEND);
    $im = imagecreatefromstring($data);
    if ($im) {
      header('Content-Type: image/jpeg');
      imagejpeg($im,'../arduino/images/curop.jpg');
      imagedestroy($im);
      file_put_contents('colo.txt',"Successfuly");
    } else {
      file_put_contents('colo.txt','Error.');
    }
  }

此外，我还有一个存储 PHP 页面中所有字节的文本。这些字节似乎无法制作图像。所以现在我被困住了。我不知道该怎么办。谁能帮我解决这个问题？

我还尝试下载文本文件并尝试在我的 PC 上使用 PHP 进行转换，但我收到了以下警告：imagecreatefromstring(): Data is not in a recognized format.

我忘了告诉我我正在使用 Arduino Due。
