Answer 1

You should ..

echo "(".implode(',', array_map(function ($v){ return $v['num'];},$yourarray)).")";

Working Demo

Explanation :

You can't directly use implode() on a MD array. So use an array_map() to grab all those values with num key and then subject that to your implode().

Answer 2

This should solve your problem

$result = implode(',',array_column($a,'num')));

Extract values and implode them
