You have to update the php ini config file with in your host provider s server  trust me on this  more than likely there is nothing wrong with your code  It took me almost a month and a half to realize that most hosting servers are not up to date on php ini files  eg  php 5 5 or later  I believe

This error happen usually when tables in the query doesn t exist  Just check the table s spelling in the query  and it will work

OK  i just fixed this error   This happens when there is an error in query or table doesn t exist   Try debugging the query buy running it directly on phpmyadmin to confirm the validity of the mysql Query

The query method can return false instead of a result set in case there is an error  That is why you get the error on the fetch assoc method call  which obviously does not exist when  result is false   This means you have an error in your SELECT statement  To get that error displayed  do this     result    conn- gt query  sql  or die  conn- gt error     Most probably you have a wrong spelling for the table name or a column name  Maybe when moving to the host you did not create that table correctly  and made a spelling mistake there   You should in fact see the same error when executing the same query via phpAdmin   Also  replace this line   while   row    result- gt fetch assoc        null     with just   while  row    result- gt fetch assoc        You could also add this for debugging   echo  number of rows       result- gt num rows

Please use if condition with while loop and try   eg   if   result    conn- gt query  query             fetch associative array        while   row    result- gt fetch assoc                    free result set         result- gt free
