Advanced mySQL OOP Class

First off you may want to organize your main directory and sub directories so that you can find all your things easier.
My Directory Structure:
Code

--Main--
--Inc
----Classes
--Lib
--Images


If you have a classes folder make this file within that directory: mysql.class.php

In this file you will want something similar to:

To use this you will want to open your configuration main file and type something a bit like:
PHP Code
1
2
3
4
5
6
7
8
9
10
11
12
13
<?php
require("mysql.class.php"); //get our class file
    
$dbinfo = array(
    
"hostname" => "localhost",
    
"username" => "root",
    
"password" => "",
    
"database" => "sqltest",
        ); 
//all your database information
$MySql = new mySQL//create a new mySQL Clss for the var: $MySql
$MySql->db $dbinfo//set database info
$MySql->__Connect(); //and finally Connect :D
?>


Real Quick lets run a query through our phpMyAdmin:
Code

CREATE TABLE `test` (
`id` INT( 11 ) NOT NULL auto_increment,
`name` VARCHAR( 255 ) NOT NULL,
`data` VARCHAR( 255 ) NOT NULL,
PRIMARY KEY(`id`)
);

INSERT INTO `test` (`name` ,`data`) VALUES ('Bob', 'Old');


In a new file maybe named test.php you could have:
PHP Code
1
2
3
4
5
6
7
8
9
10
<?php
require("config.php");
$get_data $MySql->sqlQuery("SELECT * FROM `test` ORDER BY `id` ASC"); //get all data ordered ascending by id
while($objects $MySql->fetchArray($get_data)){ //lets loop the data
echo "$objects[name] is $objects[data]"//Couldn't think of anything else but yeah echo data
//end the loop
echo "<b>Total Queries</b>: ".$MySql->sqlCount()."&nbsp;<b>Execution Time</b>: ".$MySql->getTotalTime()."\n";
$MySql->__Disconnect(); //hehe close connection x]
?>


Please alert me of any mistakes you may find and i shall have them fixed.
