You need to remove the part that says data image png base64  at the beginning of the image data  The actual base64 data comes after that   Just strip everything up to and including base64   before calling base64 decode   on the data  and you ll be fine

The problem is that data image png base64  is included in the encoded contents  This will result in invalid image data when the base64 function decodes it  Remove that data in the function before decoding the string  like so   function base64 to jpeg  base64 string   output file           open the output file for writing      ifp   fopen   output file   wb              split the string on commas         data  0       data image png base64          data  1       lt actual base64 string gt       data   explode        base64 string            we could add validation here with ensuring count   data    gt  1     fwrite   ifp  base64 decode   data  1                clean up the file resource     fclose   ifp          return  output file
