Help with news page hack I made

[DionDev]

I am looking for some help with this. Now it works, but it doesn't seem to be as efficient as I would like it to be. I mean sometimes it takes a couple of seconds to display the page. The execution time is what I am worried about.

Could any PHP gurus give some input as to how I could improve this news page script I wrote? (it grabs news from a specified forum and spits it out onto a php page)

PHP Code:

<?php

chdir('./forums');
require_once('./global.php');
require_once('./includes/class_bbcode.php'); 

$parser =& new vB_BbCodeParser($vbulletin, fetch_tag_list());

$dbhost = 'localhost';
$dbname = '*****';
$dbuser = '*****';
$dbpass = '*****';

mysql_connect($dbhost, $dbuser, $dbpass);
mysql_select_db($dbname);
        
$sql = 'SELECT post.pagetext, thread.*
        FROM post AS post, thread AS thread
        LEFT JOIN forum AS forum ON (forum.forumid = thread.forumid)
        WHERE FIND_IN_SET(4, forum.parentlist) AND post.postid = thread.firstpostid
        ORDER BY thread.dateline DESC
        LIMIT 5';

$sqlresult = mysql_query($sql) or die(mysql_error());
$count = mysql_num_rows($sqlresult);

while ($row = mysql_fetch_array($sqlresult))
{
  $subject = $row['title'];
  $poster = $row['postusername'];
  $posterid = $row['postuserid'];
  $time = date("D, M j, Y", $row['dateline']);
  $replies = $row['replycount'];
  $id = $row['threadid'];
  $text = $parser->do_parse($row['pagetext'], true, true, true, true, true, false);
  
  if ($replies == 1)
    $replytext = 'reply';
  else
    $replytext = 'replies';
  
  echo "<b>$subject</b>";
  
  echo '<br>';
  
  echo '<font style="font-size: 8pt;">';
  echo "Posted by <a href=\"forums/member.php?u=$posterid\">$poster</a> on $time (<a href=\"forums/showthread.php?t=$id\">$replies $replytext</a>)";
  echo '</font>';
  
  echo '<br><br>';
  
  echo $text;
}

echo '<br><br><div style="float: right;"><a href="forums/forumdisplay.php?f=4">News Archive Forum</a></div>';

?>

One it is best to use vBulletin db functions so you only use one database connection.

But if you want to stay with the mysql default functions, it would probably be best to change your code to this.

PHP Code:

chdir('./forums');
require_once('./global.php');
require_once('./includes/class_bbcode.php'); 

$parser =& new vB_BbCodeParser($vbulletin, fetch_tag_list());

$dbhost = 'localhost';
$dbname = '*****';
$dbuser = '*****';
$dbpass = '*****';

$dbconnection = mysql_connect($dbhost, $dbuser, $dbpass);
mysql_select_db($dbname, $dbconnection);
        
$sql = 'SELECT post.pagetext, thread.*
        FROM post AS post, thread AS thread
        LEFT JOIN forum AS forum ON (forum.forumid = thread.forumid)
        WHERE FIND_IN_SET(4, forum.parentlist) AND post.postid = thread.firstpostid
        ORDER BY thread.dateline DESC
        LIMIT 5';

$sqlresult = mysql_query($sql, $dbconnection) or die(mysql_error());
$count = mysql_num_rows($sqlresult);

while ($row = mysql_fetch_array($sqlresult))
{
  $subject = $row['title'];
  $poster = $row['postusername'];
  $posterid = $row['postuserid'];
  $time = date("D, M j, Y", $row['dateline']);
  $replies = $row['replycount'];
  $id = $row['threadid'];
  $text = $parser->do_parse($row['pagetext'], true, true, true, true, true, false);
  
  if ($replies == 1)
    $replytext = 'reply';
  else
    $replytext = 'replies';
  
  echo "<b>$subject</b>";
  
  echo '<br>';
  
  echo '<font style="font-size: 8pt;">';
  echo "Posted by <a href=\"forums/member.php?u=$posterid\">$poster</a> on $time (<a href=\"forums/showthread.php?t=$id\">$replies $replytext</a>)";
  echo '</font>';
  
  echo '<br><br>';
  
  echo $text;
}

mysql_close($dbconnection);

echo '<br><br><div style="float: right;"><a href="forums/forumdisplay.php?f=4">News Archive Forum</a></div>';
