I used json_decode to format the data but it did not work. I want to format the output so that I can use its values in program.

Answer 1

Here is some simple PHP code for looping over the resulting object from calling json_decode.
$newdata = json_decode($data);
foreach($newdata as $entry) {
echo "{$entry->firstName} is {$entry->status}. " .
"Their key is {$entry->registrantKey}.<br />\n";
}
You can access any of the properties you see in the returned json from the decoded object.
Since you get an array of objects, you can loop over each entry (as shown above), or access a specific entry like this:
$third = $newdata[2]->firstName;
Hope that helps get you started.

Answer 2

Try converting it to an array first:
$newdata = (array) json_decode($data, true);
