  1. hi, I am try to learn PHP and MySQL with the help of Larry's excellent book. Most of the time, I find the book easy to follow and I can find the answer I need, however I have now hit a wall! I want to count the amount of rows in a table that meet a certain criteria and then use this number in a PHP while loop. My query is - $SQL_count = SELECT COUNT(*) FROM college_notes WHERE link_code = 'CHES' and I used this $result_count = mysqli_query($dbc, $SQL_count); My problem is that the variable $result_count doesnt seem to be usable. If I use echo to dump it on the screen, i get this - Catchable fatal error: Object of class mysqli_result could not be converted to string in/home/www I have also tried using AS to get an alias and $result_count['alais'] but got a message stating that the variable wasnt an array. Thanks in advance for any help! Dave
