MP3

MP3 (MPEG-1 Audio Layer-3) is an audio compression format that creates files that can be easily sent or downloaded across the internet.

Using ripper and encoder applications, CD tracks can be converted to MP3 and reduced in size by a factor of 12. MP3 files have varying degrees of sound quality, depending on the encoding settings that are used during the compression process.

PHP


PHP is an open-source scripting language that is embedded alongside HTML to perform interactive functions, such as accessing database information. PHP is similar to Microsoft’s active server page technology, but is used primarily on Linux web servers (or Windows servers with add-on software). An HTML page that has PHP script usually has a “.php” extension. Visit Webmonkey’s Tutorial:PHP Tutorial for Beginners to learn how it works.
