Easily search and use the commands that you had used in the past

Imagine a situation where you used a long command couple of minutes/hours ago and you have to use it again. Problem is that you cannot remember the exact command anymore.
Reverse search is your savior here. You can search for the command in the history using a search term.
Just use the keys ctrl+r to initiate reverse search and type some part of the command. It will look up into the history and will show you the commands that matches the search term.
ctrl+r search_term

By default, it will show just one result. To see more results matching your search term, you will have to use ctrl+r again and again. To quit reverse search, just use Ctrl+C.

As a PHP programmer we have learned how to access database by using either MySQL and MySQLi. As of PHP 5.1, there's a better way. PHP Data Objects(PDO) provide methods for prepared statements and working with objects that will make you far more productive! PDO Introduction :        PDO provides a data-access abstraction layer, which means that, regardless of which database you're using, you use the same functions to issue queries and fetch data. PDO does not provide a database abstraction; it doesn't rewrite SQL or emulate missing features. Database Support:       The extension can support any database that a PDO driver has been written for. The following drivers currently implement the PDO interface: PDO_CUBRID Cubrid PDO_DBLIB FreeTDS / Microsoft SQL Server / Sybase PDO_FIREBIRD Firebird PDO_I...
