A little function that does some basic checking for data input by a user. Should get rid of code injection ;-)

PHP function to validate an email address.

This simple function will check if a url is valid (going by parse_url()) and if it's 'online' - by seeing if it returns a 302, 301, or 200 status code.

This small snippet will not allow _POST requests from a 'foreign' domain. It relies on the HTTP_REFERER variable.

This function will reverse the affects of register_globals

This is a simple PHP script that will show whether a certain port/socket of a certain computer is currently open/active.

This multiple-use PHP script will randomly generate content based on a randomly generated number.

Enforce loadig fresh script code for the external javascript files. Compatible with HTTP 1.0.

This snippet illustrates following:

1. Using http request to get the data
2. Parsing RSS feeds
3. Sending email

This perl subroutine uses the CPAN module Mail::Webmail::Gmail to iterate through a Gmail account searching for a particular string. If a match is found, the sender's name along with his/her email address, the subject, and the "blurb" is printed to standard out. Also, all messages found will be archived automatically within Gmail to clear the message from the inbox folder. The subroutine returns the number of messages found back to the calling environment.

Sample invocation: check_email(username, password);

By default, the subroutine will use encryption to connect to Gmail however, by setting encrypt_session to '0' will disable encryption.
