使用php从iphone app处理json base64编码图像

Question

I am working on a php REST API that will be used with an iPhone app. It is another developer who develops the app. From that app it is possible to take a image and upload it to the webserver. I will recieve the images from the iphone as base64 with json, but I am unsure how to process them with a PHP script. The images will be send like:

{
"image1":"Base64Data",
"image2":"Base64Data",
"image3":"Base64Data",
"image4":"Base64Data"
}

will it be something like:

$image1 = json_decode($jsonData);

Is it possible to get the same / a like data from the base64 string as from $_FILES[] upload? When images a upload the normal way from the website, they are being handled with a cropper and thumbnail generator. I want the base64 images to be handled the same way.

Answer 1

your json which looks like this

{
"image1":"Base64Data",
"image2":"Base64Data",
"image3":"Base64Data",
"image4":"Base64Data"
}

will not be something like:

$image1 = json_decode($jsonData);

more like this

$json = json_decode($jsonData, true);
$image1 = $json['image1'];

There will be no values similar to $_FILES except the data of the file.

you can easily do

$imagedata = base64_decode($image1);
file_put_contents("file.jpg", $imagedata);
