The Perl Programming Language

Perl is often used for CGI. The source code is separate from any web page source code files it might have an effect on. (A Perl script can, however, generate web page source code from within itself.)
Perl CGI can be used for many things:

1. Generate web pages on the fly.
2. MySQL and other databases can be read and manipulated.
3. Import and parse or display files on the server.
4. Import and parse or display files of information from other domains (if that information is also available by typing the file's URL into a browser's address bar.)
5. Use an SSI tag to launch and execute a Perl script.

For those who prefer the source code of the software be separate from the web page file it affects, Perl is a preferred language.
Perl can also be used for things not CGI. Examples are nightly removal of old temporary files, consolidating statistics, and emailing "your membership is about to expire" notices.

Yeah i agree with you Perl is a flexible, feature-rich and powerful dynamic programming language. Perl code is very succinct and can be written very quickly, while still performing well in most cases. It is very usual to achieve in one line of Perl what requires 100's of lines in C and other languages.
