URL encoder and decoder to encode strings using the URL encoding standard (%[hex]). This script utilizes both, PHP's built-in urlencode() and urldecode() functions, and a custom function that encodes all characters except letters and numbers. And, of course, I have included the simple script below for those that are curious.
show me!

Being that I am not as skilled in PHP as I am in ASP or ASP.NET, I did not realize that PHP already had functions for URL encoding and decoding, urlencode() and urldecode(), respectively. I started this simple page by creating my own function and naming it, well, urlencode(). After noticing that my text editor (UltraEdit) colored the word, I did a simple Google search and realized that I was wasting my time…or was I? I kept the custom script as it encodes more characters than the standard PHP urlencode() function does, such as the period character (“.”).

IT is not just a job but also a passion. Everything I have accomplished, both personally and professionally, has been generally entertaining, bordering on fun. Some of my projects, such as working with SharePoint Services workflow actions in Visual Studio or building a custom iSCSI SAN using the OpenSolaris, ZFS and COMSTAR, has been quite rewarding. You may think nerd...I think developing a new trend!
