you are doing encode and decode at same time $object = json_decode (json_encode($v->params), TRUE); can you explain it once — Forge Web Design

@ForgeWebDesign This is a pretty common practice to convert an array that contains JSON strings to an actual array. — GrumpyCrouton

The data seems the wrong way round as it's the key of the array rather than a value.

So using array_keys()[0] to get the first key and then json_decode this...

$data = json_decode(array_keys($v->params)[0]);

you can then use the $data object to get at the values...

echo $data->username;

Try it with $v->params instead.
