如何将Base64图像转换为文件类型

I want to inject my site to ios device and I need to use the device's camera.

我想将我的网站注入ios设备,我需要使用设备的相机。

It returns a base64 image type. When the camera is finished, can I convert that to a file type?

它返回base64图像类型。相机完成后,我可以将其转换为文件类型吗?

If mobile device return a file path, can I reset it to a input element (with type="file") and then reuse fileReader to read it? How to do it?

如果移动设备返回文件路径,我可以将其重置为输入元素(type =“file”)然后重复使用fileReader来读取它吗?怎么做?

If mobile device return a file path, can I set the <img> element's src attribute? will it show?

如果移动设备返回文件路径,我可以设置如何将Base64图像转换为文件类型元素的src属性吗?它会显示吗?

you can get it from client in base64 format and the convert it to image file in server side using php:

你可以从base64格式的客户端获取它,并使用php将其转换为服务器端的图像文件:

function base64_convert_to_jpeg($base64_string_in, $file_out) {
   $fp = fopen($file_out, "wb"); // this open file writable and binary 

   $data = explode(',', $base64_string_in);  //explode base64 string with ',' character

   fwrite($fp, base64_decode($data[1])); //decode base64 and write it to file
   fclose($fp);  //close the file 

   return $file_out; //return jpeg file

}

if you have problem with it or you have any question about that, replay that for me... good luck
