解码base64图像并使用php将其上传到服务器

Question

我从图像传递图像作为base64字符串。然后我想解码它，重命名并上传到我的服务器文件夹。我无法得到这个工作，所以显然我在这里做错了什么。任何帮助，将不胜感激。

我的代码：

$image = $_POST['image-data'];//base64 string of a .jpg image passed from form: 

$image = str_replace('data:image/png;base64,', '', $image);//Getting rid of the start of the string: 
$image = str_replace(' ', '+', $image); 
$image = base64_decode($image); 

$ext = strtolower(substr(strrchr($image, '.'), 1)); //Get extension of image 

$lenght = 10; 
$image_name = substr(str_shuffle("123456789abcdefghijkmnopqrstuvwxyzABCDEFGHJKLMNOPQRSTUVWXYZ"), 0, $lenght); 

$image_name = $image_name . '.' . $ext; //New image name 

$uploaddir = '/var/www/vhosts/mydomain.com/httpdocs/img/'; //Upload image to server 
$uploadfile = $uploaddir . $image_name; 
move_uploaded_file('$image', $uploadfile);

使用文件把内容，您可以将文件移动到文件夹

$file = $_POST['image-data']; 
      $pos = strpos($file, ';'); 
      $type = explode(':', substr($file, 0, $pos))[1]; 
      $mime = explode('/', $type); 

      $pathImage = "path to move file/".time().$mime[1]; 
      $file = substr($file, strpos($file, ',') + 1, strlen($file)); 
      $dataBase64 = base64_decode($file); 
      file_put_contents($pathImage, $dataBase64);
