Pagination class is very useful when we are handling a very large set of data. With it, users can see a page of data sets for only 10 or 20 rows and provided with page navigation where user can go to the next and previous page or directly jump to a page number. CodeIgniter has a class for doing this, but we must make a link to the data to be paginated to make it works correctly.
This article show you how to make the link between pagination class and database class to make the pagination works on a table that has a large set of data inside it.

Passing parameter to a web page build with CodeIgniter (CI) can be done by using either POST variables which comes from HTML form or from the URI. But, different from traditional web application, by default CI only recognizes a segment based URI rather than query string format for passing parameter by URI.
In some circumstances we do need to use the query string to pass data to our page, which in this case using PHP global variable $_GET. By default, CI will not allow us to read the content of $_GET variable but instead using the URI class $this->uri->segment(the_segment_number).

Sometimes we need to know where an email was sent from, the IP address, the country, or even the city. There’s a tool from WhatIsMyIPaddress.com called Trace Email that can help you to do that. This tool attempts to locate the source IP address of an email based on the email headers, thus we can trace where did the email come from. To use the tool just copy and paste the full headers of the email you’ve received into the box below and press submit. When the page reloads scroll down to the bottom for the email header analysis and results.
This article explains how to trace an email that was sent with Gmail and Thunderbird. With the explanation provided, you should be able to trace any email sent with any other email programs like Yahoo Mail or Ms Outlook.
At the time of this writing, WhatIsMyIPaddress.com is in the process of compiling a set of instructions to obtain email headers from a variety of popular webmail services and email applications.
