Here is a collection of good PHP code libraries I somewhat use to create web based applications. This collection is about PHP only, in another article I will shortly tell you some good Python and Javascript/AJAX libraries.

Zend Framework

The Zend Framework is an object-oriented framework which is focusing on web 2.0 applications. It contains a lot of APIs to webservices like Google, Amazon, Yahoo!, Flickr.

CSV Utilities

PHP CSV Utilities or PCU, is a small, open source PHP library to simplify working with CSV files.

phpExcel

This project provides a set of classes, which allow you to write to and read from different file formats, like Excel 2007, PDF, HTML, … This project is built around Microsoft’s OpenXML standard and PHP.

phpQuery

MC_Google_Visualization

MC_Google_Visualization provides simple support for integrating Google Visualization charts and graphs with your own internal database. It includes a complete parser for the Google Visualization Query Language, giving you the same ease of pivoting and formatting data from your database as is currently possible with Google Spreadsheets.

pChart

pChart is a PHP class oriented framework designed to create aliased charts.

FirePHP

FirePHP enables you to log to your Firebug Console using a simple PHP method call.

SimpleTest

The SimpleTest PHP unit tester is a PHP unit test and web test framework. It has support for SSL, forms, frames, proxies and basic authentication.

If you know any more good PHP libraries and tools, just leave a comment.

Today I want to tell you my 10 favorite Android applications. As you might have guessed already, I have one of those T-Mobile G1 and I love every bit of it!

twidroid

This applications is my trip to twitterland, every while and then, when I am not at my desktop, I look up my latest tweets or post a “Hello” here and there.

Timeriffic

Since my G1 is giving a “beep” everytime I get an E-Mail I use this application to set specific time frames when the device shall be muted or reactived. I don’t mind the beep, but my girl friend was driving me nuts everytime she woke up because of it.

Battery Status

No need to explain this one, don’t you think?

Delicious Bookmarks

Bookmarks, like in the sidebar to the right side, can be stored on this web platform. Sharing them can help others (and yourself) find useful information (if you don’t want to rely entirely on search engines like Google).

RTM Tasks

Helps me keeping track of my ToDo lists.

Toogle WiFi

One-click solution to activate the wifi controller. When I am home, I don’t want to miss my DSL broadband connection.

KeePassDroid

Keeping track of all the password you collect in the wilderness of the internet keeps your brain very busy. Fortunately there are tools like this which help you save your precious keywords in an encrypted database. Don’t forget the master keyword!

ConnectBot

Mobile SSH client with key authentification. When this server goes wild, I have used it the wrong way

klickTel

This application is a mobile client for the an online directory for phone numbers and industries. You can get current traffic informations based on your location and it helps you find the nearest coffee house or cashpoint. It’s for Germany only.

The Schwartz Unsheathed

Who doesn’t want to have their own personal light sabre?!

The Update for Android to Version 1.5 is available to Download from Google. I recently updated my G1 to the new version sucessfully. Please remember that this is probably a European version of Android (don’t know for sure), so please be careful @ US guys. Here is the tutorial:

Download the file and rename it to update.zip. Then put it in the root folder on your G1′s SD card. Then turn off your G1 completly. To start the service update press the key combination [Home]-[Quit], and keep them pressed until a warning sign appears on the screen. Then press [Alt]-[S] to start the update. After installation the G1 reboots twice and then its completed. You have to have Android v1.1 to install the update.

Similar to my friend Sascha I have decided to put up a second website where I focus on relevant content regarding my work and my hobby around Web Development.

Since most people probably don’t know me (yet! ) here a short introduction of myself:

My name is Christian Krahn and I work for over 6 years now as IT Specialist, concentrating on Web Development. Primarily I am using PHP and Python now, but I used to work with Perl as well. My current field of expertise includes extensive knowledge of the Google AdWords API and building applications around it, in PHP as well as in Python. But I am also deeply interested in social media and mobile application development, e.g. BlackBerry, iPhone and Android development (more on programming server side interfaces than client side applications though).

Ok, that’s it about me in some short sentences. For more german info about me visit my other blog @ christiankrahn.de.
