php changing values

[Monkuar]

i use this query

$result4 = $db->query('SELECT imgaward FROM users WHERE username="'.($cur_topic['poster']).'" ') or error('Unable to fetch category/forum list', __FILE__, __LINE__, $db->error());

 

and i need to change

"'.($cur_topic['poster']).'"

or w/e to something that switches on a if statement

 

possible?

 

 

This way i dont have to have 3 query's runned per page like

 

$result4 = $db->query('SELECT imgaward FROM users WHERE username="'.($cur_topic['poster']).'" ') or error('Unable to fetch category/forum list', __FILE__, __LINE__, $db->error());

 

$result4 = $db->query('SELECT imgaward FROM users WHERE username="'.$cur_topic['last_poster'].'" ') or error('Unable to fetch category/forum list', __FILE__, __LINE__, $db->error());

 

and so on lol so i can save some bandwidth
