connecting to DB with php

[garrensilverwing]

Ok I have a new php problem. I read a tutorial on connected to a database with php but I am having some problems. I get this error message when I try to run the script

Fatal error: Class 'DB' not found in /home/frostbit/public_html/php/protected/db_connect.php on line 12

idk what is wrong with it also how do i make a file protected so only I can use it?

 
<?php
 $db_engine = 'mysql';
 $db_user = 'admin';
 $db_pass = '**';
 $db_host = 'localhost';
 $db_name = '**';
 $datasource = $db_engine.'://'.
  $db_user.':'.
  $db_pass.'@'.
  $db_host.'/'.
  $db_name;
 $db_object = DB::connect($datasource, TRUE);
 if(DB::isError($db_object)) {die($db_object->getMessage());}
 $db_object->setFetchMode(DB_FETCHMODE_ASSOC);
 include('check_login.php');
?>

if you take all of that above and put it in a function it can only be accessed from within your script. It's really pretty safe either way.

I think what you're trying to do is $db_object = mysql_connect(....) because DB::Object doesn't exist

ok so if i put it all in a function say

function dbconnect()

i would have to do

require 'protected/db_connect.php';
dbconnect()

on any page that i need to connect to the database right?

ok so i made the change and i get these errors now:

Warning: mysql_connect() [function.mysql-connect]: Lost connection to MySQL server at 'reading initial communication packet', system error: 113 in /home/frostbit/public_html/php/protected/db_connect.php on line 12

Fatal error: Call to undefined function iserror() in /home/frostbit/public_html/php/protected/db_connect.php on line 13

 
<?php
 $db_engine = 'mysql';
 $db_user = 'admin';
 $db_pass = '**';
 $db_host = 'localhost';
 $db_name = '**';
 $datasource = $db_engine.'://'.
  $db_user.':'.
  $db_pass.'@'.
  $db_host.'/'.
  $db_name;
 $db_object = mysql_connect($datasource, TRUE);
 if(DB::isError($db_object)) {
     die($db_object->getMessage());
 }
 $db_object->setFetchMode(DB_FETCHMODE_ASSOC);
 include('check_login.php');
?>

i see what i am doing wrong, i reread the tutorial and i am missing something important: require_once 'DB.php';
Edit:
ok ive changed my pace and i tried byron's tutorial this is my code:

<?php 
$username = "frostbit_admin";
$password = "**"; 
$server = "localhost";
$database="frostbit_members";
$mysqlconnection = mysql_connect($server, $username, $password); 
if (!$mysqlconnection) { 
   die('There was a problem connecting to the mysql server. Error returned: '. mysql_error()); 
} 
$databaseconnection = mysql_select_db($database); 
if (!$databaseconnection) { 
   die('There was a problem using that mysql database. Error returned: '. mysql_error()); 
} 
 ?>

it pretty much works but i am getting denied access to the local host even though i set up the mySQL database through cpanel

[garrettroyce]

did you give the user rights on the database you want to connect to?

[garrensilverwing]

oh wow i forgot to add them to that particular database awesome! it works now i can connect to the database
