Easy Calendar Applications
In this tutorial, we will use the mstore calendar driver. The mstore calendar driver uses a local file storage format. Another driver that can be used is the ICAP driver, which allows access to remote calendar stores. One things that makes the MCAL library very different than other libraries is that it does not just handle "simple" calendaring. It is a feature rich calendaring library that handles dates from year 1 to year 9999, incorporating the Gregorian calendar and extrapolating back. This calendaring obviously contains events and many event objects. (It essentially uses icalendar objects and properties).
PHP, MySQL and imagesWilliam SamploniusJoe's used auto sales, an average sized car yard of around 150 cars has decided to make the big leap into the new millennium. First of all they had to get themselves a nice new computer, with that new computer came the "Internet". After a few weeks of searching the internet they decided to go all out, now they wanted a web site of their own. And it just so happens that Joe's good friend knows a little HTML, three days later Joe's used auto sales was online and ready for business. It wasn't long before they realized they were not going to get very far with that site. They needed something where they could add, modify and delete listings in a database. Well, to make a long story short they ended up contacting me. And of course I said I could do it. So, that day I had to find out what type of database to use. After asking a few questions I decided to create a database using PHP and MySQL.
HTML_GraphsTim Perdue
I didn't want the lack of GD to stifle me too much, so I started hunting around for a way to generate html-based graphs and charts. Fortunately, someone had already gone to the trouble of writing up a class to handle that. Phil Davis at WebGuys provided a nifty class called HTML_Graphs. At first, I was a little taken back by the complexity of the class. It does all kinds of things, from vertical bar charts to multiple horizontal bar charts. Because I knew I was going to use the class a lot, I spent some time creating a couple of wrapper functions. |
Binary Data + MySQL + PHPOr: How to store images directly in the sql database
If you want to store binary data like images and html files directly in your MySQL database, this column is for you! I will show how you can store the data via the HTML forms "File" feature in your database and how you can access and use this data in your webproject. If you have read the article "PHP, MySQL and images" by William Samplonius here on phpbuilder.com, this might be interesting for you as William stores the binary data somewhere on your harddisk (using a shell command), instead of storing the image directly in the Sql-Database.
The Power of CVSTim Perdue
CVS isn't just for hardcore software developers. I'm finding that it is really useful for developing PHP web sites (or really any HTML site). Since I have multiple machines in multiple locations across the US, it's super-convenient for me to store all my code in my main CVS tree in West Des Moines, IA and access from my desktop in SunnyVale, CA and my laptop before I jump on a plane.
"WebBox" Architecture in PHP

One of the latest crazes on the 'net has recently been online calendars.

When I compiled PHP on my LinuxPPC box, I didn't have GD installed and
didn't want to add another layer of complexity by compiling it in. GD
will let you do all kinds of cool things - creating gifs, complex charts, etc,
if you use libraries from the Sample Code Archive here on this site and PHP's
built in functionality.
Almost any interactive website breaks down into logical divisions. For
example, there is sometimes a "People" section of the site where you can
create an "account" for yourself, log in to your account, edit your account,
etc; on e-commerce sites there's always an "Order" section where you create
order, check an order's status, cancel an order, update an order, etc. In
the webbox architecture each of these functional areas is made into a PHP
object with a thin wrapper around it to allow each of the object's functions
to be called and receive arguments via URL, form action or via PHP script.
The object plus its thin wrapper layer and other supporting files, I call a
"webbox." The functions that can be called on the webbox, I call
"boxactions." I use the term "webbox" for the wrapped object because this
entity isn't really a pure PHP object anymore (it can't be subclassed) and
because of the one feature that distinguishes its "boxactions" from regular
PHP class functions -- that they can be called directly from URLs or form
actions. The implementation of this feature is the whole purpose of the webbox
architecture. Without it, "webboxes" are nothing more than regular PHP
objects, and I should not use any new terminology.
