Question

I’m trying to use json to send text and blob image information from MySQL to iPhone App.
However, someone told me that I should separate text and blob image info because blob is technically not binary – thus I have to use base64_encode(). Well…. I’m going to create two php files but want to check if it’s possible to do it in one php file. :/ I tried but n o luck yet… Is it even possible?

You can invoke json_encode, the function, as often as you want.
But throwing the output together is not going to work.

If you intended to do

print json_encode($data_array); 
print json_encode($image_blob);

Then this will lead to an invalid JSON response.
Like {"data":123} {"image":"PNG%...."}

You need to combine the data and the image blob somehow if you want this to work in one response:

print json_encode(array_merge($data_ar, array("image"=>$image_blob)));
