Extract data from php array

I have the following `array` in my `Moodle` `plugin`: Array ( [0] => stdClass Object ( [id] => 32 [sessionid] => 5 [sessiontimezone] => CET [timestart] => 1464071400 [timefinish] => 1464102000 ) [1] => stdClass Object ( [id] => 33 [sessionid] => 5 [sessiontimezone] => CET [timestart] => 1465281000 [timefinish] => 1465311600 ) ) How to get the `data`. Right now, when I make: $pluginsessiondates = $DB->get_record('plugin_sessions', array('id'=>$sessionid)); I get only data from the `frist` `array` `[0]` How to `get` the data from every `array` `key` and then the `single` `values`? Thanks in advance.
