You print a var_dump of it. That'll tell you whether it's an object, an array, a string, an int, a bool, ... and you'll get type and value of all contents (each value of an array / each property of an object)

Eg:

<?php
print var_dump($term);
?>

Install the devel module and use its nifty functions:

Very briefly, the PHP function is_object($var) will return true if $var is an object and false otherwise,
