DevShed: User Management in a PHP Invoicing System
94154
DevShed has posted the last part in their look at the creation of an invoicing system to help you manage your clients today. This time, they focus on the management of users of the system (not the clients to invoice, that was this part).   In this fourth and final article covering the creation of a PHP invoicing system, we're going to put together the user management section. In this section we will be able to view all available users and do all the associated things like deleting or updating user details. We are also going to be able to add new users.   They start with grabbing the information of the current users of the system and listing them out. This allows simple modification and deletion of any of the users on the list. They give the code (and screenshots) for the user modification screen and show you how to set up an email reminder that sends out to the clients when a bill hasn't been paid.

On LinuxJournal today, there's a new article from Marco Tabini about the power of PHP as a multi-purpose language (and not just for web pages anymore).

DevShed is continuing their series on working with an invoicing system in PHP with this second part, a look at the actual invoicing system they created the login for previously.   If you're running a business in which you're invoicing clients, you need some way to keep track of which invoices have gone out and which clients have paid. In this second article of a four-part series that covers the creation of a PHP invoicing system, we create the parts that deal with this kind of invoice management.   First off, they build out the select to pull out the invoice information and create the page to display the results on. They move to the other side of things, and create the form to set up an invoice, outputting it in a PDF format. To make it easier to see which of the invoices are unpaid, they also create a small section at the top of the list. And, last but not least by any means, they show you how to enter in a brand new invoice record into your database using the FCKeditor to make entering the actual contents of the invoice simple.

As Ed Finkler points out there's a new article posted (written by him) on the C7Y site (from php|architect) talking about his Inspekt library - an introduction to the filtering library showing how to help make your applications safer.   Inspekt is a library for PHP4 and PHP5 that aims to make safe input handing easier, and unsafe actions more difficult. Inspekt establishes a new development approach by wrapping input within "cage" objects, and requiring the developer to use validation and filtering methods to test and manipulate the input data. This article provides a brief introduction to Inspekt and its capabilities.   The article covers all of the basics - what the library can do for you, how it integrates into your application and how it helps to protect you from potential problems with the data in your superglobals ($_GET, $_POST, $_REQUEST, etc).

DevShed continues their series covering SQLite in PHP5 today with the final tutorial - "Additional Methods for Using SQLite with PHP 5":   The list of additional features offered by SQLite is really impressive. Therefore, in this last article of the series, I'll be taking an in-depth look at them. This will complete our analysis of this excellent RDBMS integrated with PHP 5.   First up is a look at the usage of the seek and lastInsertRowid functions followed by the changes and queryExec methods. They show how to use the createFunction method and show one of the more advanced features of SQLite - creating a database that only exists in the server's memory.

Joshua Eichorn notes in a quick post that, due to a last minute change, he will be speaking at php/db|works this year.   He'll be giving two Ajax sessions:  Scaling with Ajax (Wednesday @ 10:15) Javascript Light and Sweet (Wednesday @ 14:45)    Check out the full listing schedule over on the php|architect site for complete details on the whos and whens of each day of the conference. And, of course, you can still sign up for the conference too!

A great presentation by Ilia Alshanetsky from the International PHP Conference 2004. The only thing I would like to point out is that MMCache is still being actively developed, as evidenced by the CVS activity at sourceforge.  PS: You might need to use Mozilla to view this. IE sometimes doesn't work properly. I thought IE was a defacto standard :-)

The Zend Developer Zone has posted a review of Packt Publishing's "Learning PHP Data Objects" book writen up by Akash Mehta.   In Learning PHP Data Objects, the author Dennis Popel examines this new [database access] system and explains how to begin using PDO in development as a replacement for typical database drivers. The book is an excellent introduction to the data abstraction layer and also provides essential insight into the inner workings of database interaction with PHP.   Akash talks briefly about the history of PDO and what it can be used for first, then gets into the contents of the book (things like the intro chapters and the quality of the writing). The thing he thinks makes the bok stand out, though, is the examples and sample code that reflect both simple methods and more complex issues PDO developers might run into.

Mike Wallner has thrown together some stats for the latest edition of the pecl/http package to test its response performance.   The results surprised me, because it clearly shows that the performance drop for starting the PHP engine and doing the neccessary negotiation to provide caching is not that bad.   There's a chart of the results as well as a full PDF with all of the stats the graph maps out. He includes the legend to make the graph easier to understand.

Knut Urdalen shares a note about the latest issue of the International PHP Magazine - the December 2007 issue - that he has an article in.   The December issue of International PHP Magazine includes my latest article "Seamless AJAX with PRADO - An introduction to ActiveControls". In this article I discuss some AJAX design patterns and show you how to make use of them in AJAX enabled components that ships with the PRADO framework.   More information about this issue (and subscribing to the International PHP Magazine) can be found on this page of their site and details on the PRADO framework are over on the project's website.

Alexey Zakhlestin gave a talk for the PHPThinktank IRC channel recently on the topic of YAML, PHP, and some of the work that he's done combining the two.   It happened a bit of spontaneously, so noone was invited. It was my first try, to make introduction to yaml for php prgrammers, and if there is more interest I will give another talk which will cover more details, this time with proper scheduling :)   You can check out the log of the discussion for his entire talk (covering topics like what YAML is, where to get more information on it, some of its features, and a mention of the Syck library for parsing it).
