Warning: Invalid argument supplied for foreach()

Question

Warning: Invalid argument supplied for foreach() in /home/netanelb/www/Admin/confClicks.php on line 333

 foreach ($a as $key => $value1) 
        {
            $mil = $value1['latestDate'];

            $seconds = $mil / 1000;

Answer 1

It means just that — $a isn't an array, so foreach can't be applied to it.

Try using var_dump($a) before your foreach and you'll see that it is not a loop.
