mysql_num_rows equivalent for JSON in PHP

Question

Can you do a similar test when returning JSON with PHP like mysql_num_rows?

Therefore i can do an IF statement and echo a different piece of text for when there's no JSON available?

$data = json_decode("some json");
echo count($data);

how about if your json has 1 extra level... would you do count($data[0]) for ex?

Not sure what the context is but you can do

$array = json_decode($json_string);
$num = count($array);

That's if the json_string is an array.
