Hi I have been struggling with this query for a while now

I need to get the number of rows inserted into my database table, but I keep getting this error I can't seem to get rid of.

$result3=mysql_query("INSERT INTO dest_table.create_info SELECT * from 
$num_rows = array($result3);
echo $progress;

The error I get is

mysql_num_rows() expects parameter 1 to be resource, array given

It will be highly appreciated if I get this resolved
