问题描述
我如何检测的图像已经被完全或部分上传？我遇到的其中只有一半的图像已被上传一个奇怪的现象。下面的图片是由用户通过Android应用程序通过Web服务上传：
管理门户和Web服务使用Yii框架编写的。什么可能导致被这样创建的图像？ Android开发者发送基带64 codeD字符串，我去code将其方式如下：
$ profilePicture = $数据['profilePicture'];
标题（内容类型：图像/ PNG'）;
$ RND = sprintf的（％04D，兰特（0，9999））;
$文件名= $ RND。 _。时间（） 。 巴纽; //随机数+时间戳 $ uploadPath =用户:: getProfilePicturePath（）。 $ ID; 如果（！file_exists（$ uploadPath）和！is_dir（$ uploadPath））//创建只有当它不存在的目录。
的mkdir（$ uploadPath）; 如果（！的file_put_contents（$ uploadPath。DIRECTORY_SEPARATOR。$文件名，base64_de code（$ profilePicture）））
我怀疑这是原因，因为Android开发者发送的基带64 code之前文件是完全上传。或者是别的什么？
$ profilePicture等于64的基本字符串这样，

解决方案
可以使用 imagecreatefrompng 函数检查提供的图像损坏或没有。
$ SRC1 ='F：\\测试\\ 0374_1423730003.png';
$ SRC2 ='F：\\测试\\ 5030_1423722865.png'; //破$ IM = @imagecreatefrompng（$ SRC1）;
如果（$ IM）
回声创建IMG';
其他
回声没有创建，破碎的形象;
How can I detect if an image has been uploaded completely or partially? I encountered a strange situation where only half an image has been uploaded. The following image was uploaded by a user through an Android application via a Web service:
The admin portal and Web service is written using the Yii framework. What might have caused an image to be created like this? Android Developer sends the base-64 encoded string and I decode it the following way:
$profilePicture = $data['profilePicture'];
header('Content-Type: image/png');
$rnd = sprintf('%04d', rand(0, 9999));
$fileName = $rnd . '_' . time() . '.png'; // random number + timestamp
$uploadPath = User::getProfilePicturePath() . $id;
if (!file_exists($uploadPath) and ! is_dir($uploadPath)) //create a directory only if it does not exist.
mkdir($uploadPath);
if (!file_put_contents($uploadPath . DIRECTORY_SEPARATOR . $fileName, base64_decode($profilePicture)))
I doubt this is the cause, because Android Developer is sending the base-64 encode before file is completely uploaded. Or is it something else?
$profilePicture is equal to 64 base string like this,

Android side code is as below,
String imageString = Base64.encodeBytes(byteImage);
This is the class file used.

解决方案
Can use imagecreatefrompng function to check if provided image is broken or not.
$src1 = 'F:\Test\0374_1423730003.png';
$src2 = 'F:\Test\5030_1423722865.png'; // broken
$im = @imagecreatefrompng($src1);
if ($im)
echo 'created img';
else
echo 'not created, broken image';
