Simple example - getting result from MySQL database This is the most simples example, shows how to get results from database.

require_once('mysql_driver.php'); //include class file


$DB = new DB_MYSQL('localhost','3306','root','password', 'database'); //connect to database


$DB->query('SELECT host FROM user'); //send query


        $buffer = $DB->fetch()) //fetch result to array - basic method (from last query)

        echo $buffer['host']; //where 'host' is a name of desired row in table

But is better to handle variable on query to make sure that you are fetching from right query!

$query1 = $DB->query('SELECT host FROM user'); //send query
$query2 = $DB->query('SELECT password FROM user'); //send query
$query3 = $DB->query('SELECT * FROM help_topic'); //send query :)
$query4 = $DB->query('SELECT user FROM user'); //send query :)

$buffer = $DB->fetch($query2)) 

        echo $buffer['password'].'<br>';

Now you are sure, that result will come from:

$query2 = $DB->query('SELECT password FROM user'); //send query

Would you like to know number of affected rows by your query? No problem :)

echo 'Affected rows: '.$DB->numRows(); //List affected records by last query

Hmm, maybe you want to count queries and and them to your site footer? Here you go:

echo 'Queries: '.$DB->queries; //Number of queries done by script

Simple yes? All functions are simple :)

You are sitting in your admin panel and doing nothing, lets optimize our database!

$DB->optimizeDB(TRUE);  //database optimization

What?! That`s all? Yes :) You will get result like this:

accounts - Optimized
bans - Optimized
columns_priv - Optimized
db - Optimized
func - Optimized
global_storage - Optimized
guild_invites - Optimized
guild_ranks - Optimized
guilds - Optimized
help_category - Optimized
help_keyword - Optimized
houses - Optimized

...and the rest of tables

I know, you want to see all queries done by the script, and time of executions First, you will have to enable debug mode (0-2):

To do this, you need to add last parameter while initiating class:

$DB = new DB_MYSQL('localhost','3306','root','password', 'database', 2);
//This digit in the last argument means that debug level is now equal 2

Now after some queries and other functions you can paste this:

echo $DB->showSyntaxes();

The output will look like that:

0.0012 sec. SHOW TABLES
0.0909 sec. OPTIMIZE TABLE accounts
0.0151 sec. OPTIMIZE TABLE bans
0.0006 sec. OPTIMIZE TABLE columns_priv
0.0003 sec. OPTIMIZE TABLE db
0.0002 sec. OPTIMIZE TABLE func
0.0116 sec. OPTIMIZE TABLE global_storage
0.0157 sec. OPTIMIZE TABLE house_data

etc...
