Default [MySQL] Help Optimize queries to select data from 2 tables

I want to do the following two thing:


1- Select all posts (with its information) belong to one thread
something like:

PHP Code:
$threadid == X;

$posts $DB_site->query("
                    SELECT post.*, post.userid FROM post WHERE (post.threadid = 
$threadid)
"
);

$post $DB_site->fetch_array($posts
giving me a list of posts, says 15 posts (15 rows)


2. For each posts (each row), there is one userid, I need to select all awards that belong to that userid
something like

PHP Code:
$alluserawards =  $DB_site->query("
                    SELECT award.* FROM award WHERE userid=
$post[userid]
"
); 
giving me a list of awards, says 5 awards (5 rows)

if I run query #2 for each of the rows, it will run 15 times, + 1 query for #1,

is there any way to optimize the queries? so that I can somehow get a list of awards for each userid.
