Altering Tables ( Drop Tables )


DROP TABLE removes one or more tables. All table data and the table definition are  removed, so  be
careful with this statement!

 DROP [TEMPORARY] TABLE [IF EXISTS] table1; 

Use IF EXISTS to prevent an error from occurring for tables that do not exist. An error is generated for
each non-existent table when using IF EXISTS.

The TEMPORARY keyword has the following effects:
              1.  The statement drops only TEMPORARY tables.
              2.  The statement does not end an ongoing transaction

Using TEMPORARY is a good way to ensure that non-TEMPORARY table is not deleted by accident.

DROP TABLE examples: 
DROP TABLE table1; 
DROP TABLE IF EXISTS table1; 
DROP TEMPORARY TABLE eu_countries_temp;

PHP INTRODUCTION

                     PHP  (recursive acronym for  PHP: Hypertext Preprocessor ) is a widely-used open source general-purpose scripting language that is especially suited for web development and can be embedded into HTML. PHP stands for  P HP:  H ypertext  P reprocessor PHP is a server-side scripting language, like ASP PHP scripts are executed on the server PHP supports many databases (MySQL, Informix, Oracle, Sybase, Solid, PostgreSQL, Generic ODBC, etc.) PHP is an open source software PHP is free to download and use Why PHP? PHP runs on different platforms (Windows, Linux, Unix, etc.) PHP is compatible with almost all servers used today (Apache, IIS, etc.) PHP is FREE to download from the official PHP resource:  www.php.net PHP is easy to learn and runs efficiently on the server side What can PHP do? Anything. PHP is mainly focused on server-side scripting, so you can...

Data Encryption

Data encryption is the process of scrambling stored or transmitted information so that it is unintelligible until it is unscrambled by the intended recipient. The intended recipient can then decode (or decrypt) the information. PHP offers multiple means to make this happen. However, none of these solutions are very effective without the applications running on secure servers and connections. The following are a list of the more common encryption functions in PHP: • md5() - MD5 is a third-party hash algorithm that PHP can use to create a digital fingerprint of a piece of data. It is next to impossible to (efficiently) recover the original text when a piece of data has been encrypted with the md5 hash algorithm. It is also vastly unlikely that any different text string will create an identical hash - a 'hash collision'. These properties make hashes ideally suited for storing an application's passwords because although an attacker may compromise a part of the system...

Delimiting PHP Code

                           PHP was originally designed to be used in conjunction with a web server, and in the case of the LAMP architecture, the Apache Web Server.  PHP applications are designed embedding PHP scripts within a web page along with its HTML.  Unlike standard HTML pages which are sent directly from the web server to the end user, PHP files are first interpreted by the PHP application which then converts the PHP script into another form for display.  This process eliminates the end user from being able to see the original PHP script that was embedded in the HTML and provides  true interaction in HTML files.  This process is similar to proprietary applications such as ASP and Coldfusion; however, PHP is Open Source and cross- platform. PHP Tags             PHP scripts are distinguished from the HTML scripts by using delimiting characters ...
