My problem is that my page loads very slow....(2-3 seconds) I tested where is the source of problem and i saw is that part: $query = mysql_query......
Here is the page:
require_once('config/db_config.php');
require_once 'class/PHPTemplate.class.php';
session_start();
//Connect to mysql server
$link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);
if(!$link) {
die('Failed to connect to server: ' . mysql_error());
}
//Select database
$db = mysql_select_db(DB_DATABASE);
if(!$db) {
die("Unable to select database");
}
$query = mysql_query("SELECT * FROM pages WHERE url_address='Skarabeol'");
$numrows = mysql_num_rows($query);
if($numrows!=0) {
while ($row = mysql_fetch_assoc($query)) {
$content=$row['content'];
$title=$row['title'];
}
} else {Echo "Page not found!";}
$rows = array(
array(1.1, 1.2, 1.3),
array(2.1, 2.2, 2.3),
array(3.1, 3.2, 3.3),
array(4.1, 4.2, 4.3)
);
$tpl = new PHPTemplate();
$tpl->add('title', $title);
$tpl->add('content', $content);
$tpl->add('current_year', date('Y'));
//$tpl->add('rows', $rows);
//$tpl->add('rows_count', count($rows));
$tpl->load('footer', 'tpl/footer.tpl');
$tpl->display('tpl/page.tpl');
?>
And it will load a template file (I tested without mysql connections and it worked fine).
Here is the config file in case you want to see it...
define('DB_HOST', 'localhost');
define('DB_USER', 'xxxxxxx');
define('DB_PASSWORD', 'xxxxxxxxxx');
define('DB_DATABASE', 'xxxxxxxxx');
What i am doing wrong?
Please let me know if you need me to show you anything else....thanks in advance!
Try using profiling to see SQL stats.
mysql> set profiling=1;
Query OK, 0 rows affected (0.00 sec)
mysql> select sql_no_cache * from tblwebentry where webID = 433382;
