Sometimes you might need to create a small server that receives pictures as a json file. There are many ways to accomplish this task and I would like to discuss one of the ways we are using here at Walden Systems, because we believe this is the most straightforward method to create a server that receives pictures as json file.

This strategy assumes that you have have php extensions installed for your web server.

First, we need to create a new php file in your web server directory. Second, we need to receive json as a string and decode the json. Third, create an file handler and save the json file as a picture.

The first thing you need to do is create a php file in the web server directory such as receiver.php.

Then you need to receive the json file as a string and decode it:

1 $string =  @file_get_contents('php://input');
2 $json = json_decode($string, true);

Then you will need create a file handler and save the data as jpg.

1 $file = 'uploads/filename';
2 $file_info = new finfo(FILEINFO_MIME);
3 
4 $mime_type = $file_info->buffer($json['image']);
5 file_put_contents($file, base64_decode($json['image']));
