It is simple to instantiate objects anywhere in your code without having to worry if the class has been included by using the __autoload function. When working with autoload you must have a naming convention that you will stick with. Throughout this example I will provide my naming conventions, but feel free to modify it to suit your style.

Create a directory in your webroot called “lib”. This will contain all your class files as well as an include file which we will be creating shortly. Name all your class files with the exact same name as the class except in lowercase letters, followed by “.class.php”. So for your Product class it would be named, “product.class.php”.

Now create a file called include.php in your lib directory with the following code:

function __autoload($name){
	$path = pathinfo(__FILE__);
	$name = strtolower($name);
	include_once("{$path['dirname']}/{$name}.class.php");
}

Create an index.php file in your webroot and include the lib/include.php file you just created. You can now instantiate any object that is available to you in your library of classes without having to manually include each class. Cool, huh?!

include_once('lib/include.php');
$object = new Class();

Dear Google Apps admin,

In order to continue to improve our products and deliver more sophisticated features and performance, we are harnessing some of the latest improvements in web browser technology. This includes faster JavaScript processing and new standards like HTML5. As a result, over the course of 2010, we will be phasing out support for Microsoft Internet Explorer 6.0 ​as well as other older browsers that are not supported by their own manufacturers.

We plan to begin phasing out support of these older browsers on the Google Docs suite and the Google Sites editor on March 1, 2010. After that point, certain functionality within these applications may have higher latency and may not work correctly in these older browsers. Later in 2010, we will start to phase out support for these browsers for Google Mail and Google Calendar.

Google Apps will continue to support Internet Explorer 7.0 and above, Firefox 3.0 and above, Google Chrome 4.0 and above, and Safari 3.0 and above.

Starting next week, users on these older browsers will see a message in Google Docs and the Google Sites editor explaining this change and asking them to upgrade their browser. We will also alert you again closer to March 1 to remind you of this change.

In 2009, the Google Apps team delivered more than 100 improvements to enhance your product experience. We are aiming to beat that in 2010 and continue to deliver the best and most innovative collaboration products for businesses.

Thank you for your continued support!

Sincerely,

The Google Apps team

Assuming you are using MySQL as your database, a data type of ‘date’ is stored as ‘YYYY-MM-DD’. In PHP we can represent the MySQL date data type by using the date() function like so.

echo date('Y-m-d'); //2010-10-02

To convert a stored date in a MySQL database to a user friendly format, use the strtotime() function to convert the date retrieved from the database into seconds. You will use this as the second parameter for the date() function that contains a string of how you want the date formatted. Check out the PHP manual’s date function page for a full list of what all the letter represent.

$db_date = '2010-10-02'; //MySQL date format
echo date('F j, Y', strtotime($db_date)); //October 2, 2010

When converting dates for entry into a database, you will likely collect the year, month, and date from a form as separate variables. If this is the case you can easily convert the variables into a MySQL ready date by using the mktime() function.

$year = 2010;
$month = 10;
$day = 2; //notice the 2 is not padded with a zero
$db_date = date('Y-m-d', mktime(0, 0, 0, $month, $day, $year));
echo $db_date; //2010-10-02

If you are using time in your code, the date function will handle time as well. The corresponding MySQL data type is “datetime”.

echo date('Y-m-d H:i:s'); //2010-10-02 00:32:15
