TempServers Source Code Released

This post is just to announce that I have released the source code from TempServers on GitHub under the MIT license. The link to the repository is below. This code has been sitting here collecting dust, so I figured I should just release it to the open source community. It might contain something useful to someone.

I also have another project about to be released to open source. It started as a small project for a single site but is developing into something potentially reusable. I'm using this as an opportunity to get more familiar with Git and the whole development cycle.

Creating A Database Connection On Demand

It may be useful to only create a database connection when you actually use it for the sake of efficiency. Here is a wrapper for MySQLi that does just that in the most simple way I could devise. A (possibly desired) side-effect is that this limits you to a single connection.

How you pass in the connection details is up to you. You can hard-code them into the mysqli initialization, put them in class constants, or pass them into a constructor that sets static properties.

<?php
/**
 * Wrapper for MySQLi
 *
 * Creates a database connection on demand
 */
class DB {
    private static $db;
    private function connect() {
        if(!isset(self::$db)) {
            self::$db = new mysqli(DB_HOST, DB_USER, DB_PASS, DB_NAME);
        }
    }
    public function __call($name, $arguments) {
        $this->connect();
        return call_user_func_array(array(self::$db, $name), $arguments);
    }
    public function __get($name) {
        $this->connect();
        return self::$db->$name;
    }
    public function __set($name, $value) {
        $this->connect();
        self::$db->$name = $value;
    }
    public function __isset($name) {
        $this->connect();
        return isset(self::$db->$name);
    }
    public function __unset($name) {
        $this->connect();
        unset(self::$db->$name);
    }
}

Usage:

<?php
$db = new DB(); // functionally identical to a mysqli object
$db->query('...');

Create Snake in JavaScript with HTML5 Canvas

Yesterday I had some spare time, so I decided to write Snake in JavaScript using the HTML5 canvas. If anything, this is a good simple example demonstrating a use of the canvas. So, here's a tutorial walking through the creation of the game.

If, for some reason, you are not familiar with the game Snake, Wikipedia explains it:

The player controls a long, thin creature, resembling a snake, which roams around on a bordered plane, picking up food (or some other item), trying to avoid hitting its own tail or the "walls" that surround the playing area. Each time the snake eats a piece of food, its tail grows longer, making the game increasingly difficult. The user controls the direction of the snake's head (up, down, left, or right), and the snake's body follows.

Here is the final product on jsFiddle (click Result to play):

This tutorial will cover:

  • Drawing on the canvas
  • Handling events in jQuery
  • Handling arrays in JavaScript
  • JavaScript math functions

Create an Upload Progress Bar With PHP and jQuery

When it comes to uploading files, users expect visual feedback, usually in the form of a progress bar. The problem is that PHP doesn’t offer a way to track file uploads in progress by default. Fortunately, there is an extension that enables this functionality and this tutorial will show how it can be combined with jQuery UI to create a progress bar.

Here is a demo of the effect we will be building in this tutorial:
