Question

I am sending an image to php server in the from of base64 string. When retrieving it from server side it shows size of the image,but it dont display the image I have posted to the service. Am using post method to send the string.

My android code://to encode the image.

Bitmap bm=BitmapFactory.decodeFile(picturePath);
ByteArrayOutputStream baos = new ByteArrayOutputStream();  
bm.compress(Bitmap.CompressFormat.JPEG, 100, baos); //bm is the bitmap object   
byte[] b = baos.toByteArray(); 
String encodedImage = Base64.encodeToString(b, Base64.DEFAULT);

Php code://to decode the image

$string=$_POST ['i_image'];
$filename="newimage.jpg";
$imagepath=base64_to_jpeg($string,$filename);

function base64_to_jpeg($base64_string, $output_file) {
    $ifp = fopen($output_file, "wb"); 

    $data = explode(',', $base64_string);

    fwrite($ifp, base64_decode($data[1])); 
    fclose($ifp); 

    return $output_file; 
}

Can anyone help me to retrieve the original image?

Thanks in advance.

Answer 1

if you want to decode your image in PHP i think this will help you

$uploadDir = 'path/to/download/dir/';
$binary = base64_decode($data_encoded_base64);
header('Content-Type: bitmap; charset=utf-8');
$fileName=md5(uniqid()).'.png';
$file = fopen($uploadDir . $fileName, 'wb');
fwrite($file, $binary);
fclose($file);

hope it helps, good luck!.
