Question

{"": "attachment-2","": "attachment-1"}

I am getting this JSON-encoded string (or an oher format… let me know) from parsing a mail and I can not change it. How can I decode it?

Answer 1

This JSON response is invalid as @ThiefMaster mentioned, because JSON doesn’t support duplicated keys.

You should contact the service you’re trying to request this response from.

In case you have a valid JSON response you can decode it using the json_decode function
which returns an object or an array (depends on the second parameter);

For example: (Object)

$json_string = '{"keyOne": "attachment-2","keyTwo": "attachment-1"}';
$decoded = json_decode($json_string);

print $obj->keyOne; //attachment-2
print $obj->keyTwo; //attachment-1

Another option is to write your own decoder function.
