2 more questions(Was: Re: psql with PHP question)

Thanks for the help, sorry for cross posting.
I have 2 more questions. I am a newb with psql and PHP. I am creating a
slashdot like site. First, what is the best way to store an article? Inside
psql or just reference the path inside psql or is there another method? I am
currently using the path inside psql then use readfile() from PHP to display
the file. Second, Can you guys with experience tell me where I am writing
code improperly or give some tips? This short code segment just displays the
article and comments posted with it. Thanks:

<?
include("./phpinc/psql.php");
include("./phpinc/func.php");
include("./phpinc/var.php");
include("/usr/local/apache/phpinc/variables");
include("/usr/local/apache/phpinc/header");

if (!$conn)
echo "Site is temporarily down";

else {
if(isset($sid)){
$q1 = pg_Exec($conn,"select author,title,path,description from article
where sid=$sid");
$arr = pg_fetch_array($q1, 0);
echo "By ". $arr["author"] .": ". $arr["title"] ."<br>";
echo $arr["description"] ."<br><br><br>";
echo $arr["path"]."<br>"; //this line is just for seign if the path is set
correctly
readfile($arr["path"]);
// echo $arr["path"];

//next 3 lines are jut for replying to the article
echo "<table width=100% bgcolor=$table1><tr><td align=right><form
action=submit.php?sid=$sid method=post>";
echo "<input type=submit value=Post></tr></td></table>";
echo "<BR><BR><BR><BR>";

//start the comments section here
$q3 = pg_Exec($conn, "select cid from comment where article='$sid'");
$maxid = pg_numrows($q3);
$q2 = pg_Exec($conn,"select uname,time,date,post,ctitle,cid from comment
where
article=$sid");
if(!empty($maxid)){
for($i=0;$i<$maxid;$i++){
$arr2 = pg_fetch_array($q2, $i);
echo "By ". $arr2["uname"] .": ". $arr2["ctitle"] ."<br>";
echo $arr2["post"] ."<br>";
echo "<a href=./submit.php?sid=$sid&cid=". $arr2["cid"] .">Reply to
this</a><br><br>";
}
}
}
}
include("/usr/local/apache/phpinc/footer");
