PHP And Mysql Training
The recent boom in field of Information Technology has seen a steep rise in the demand of trained professionals in PHP and MySQL. Software companies specializing in php mysql web development are always searching for skilled professionals for recruitment in several important projects. The current supply of PHP experts is much below par, in terms of potential growth in the industry.
To train the educated work force in this regard various MySQL and PHP training courses have been developed. These courses provide elaborate training to the professionals for developing website with the usage of these languages.
PHP Training Objectives
Two main objectives of php and mysql web development program are:
• To develop skills to create interactive and data-driven sites
• Skill development for database creation in MySQL programming
Prerequisites For Training
The most important criteria for acquiring PHP training is thorough knowledge of HTML. The course should focus on any level in programming for teaching database creation.
On the other hand there are courses for fresher in the field of php and mysql web development. Some institutes like Indus Net Academy, has launched ACE Web Developer course with the aim of teaching real applications in PHP and MySQL. These courses are beneficial for creating awareness among candidates about programming language.
Course Details
Once you get enrolled into these training courses you can acquire knowledge in areas like PHP Programming Fundamentals, Strings Functions, Arrays Functions, HTML/CSS and Forms, File Handling and Email Handling in PHP, Object Oriented PHP and Session Handling etc. On the other hand, the ACE Web Developer course emphasizes on other programming languages such as MySQL Basics, Extended PHP, OOPS in PHP 5, Exception handling in PHP 5, XML / SOAP etc.
Another vital aspect of these php mysql development courses are; 70% hands-on and 30% lecture ratio, as far as the training part of the course are concerned. By engaging the students in live projects the courses ensure that the students have a thorough understanding of the actual application of such programming languages.
So if you have some knowledge about HTML, then you can get online training as well as work as a freelancer for php mysql web development. Some of the requirements essential for learning this programming language are:
• A personal computer at home
• Linux, Windows, MacOS X, or Solaris operating system
• Web server (either Apache httpd or Microsoft IIS)
• PHP 5 or later with the PEAR extensions enabled
• MySQL 4.1 or later (5 or later recommended)
• Internet Explorer 6 or Firefox 2
PHP programmers can now get quality work through the Internet from the freelancing websites. It is an open source language and is free to install and use. This is the main reason for the increase in the popularity of this language.
Php And Mysql Programming Security
Choosing php and mysql as programming language for a website is not enough. With open source coding being one of the inherent properties of php mysql development, securing your codes becomes essential. So when one allows the users to upload files on the website, then security is definitely at stake.
PHP Programming Protection
While it is not entirely possible to protect your site, yet there are few precautions that you can incorporate for better protection of PHP programming. Some of these are:
• You should check the referrer, for being sure that the information sent is from your website and not an outside source. Since, there are maximum chances of the information being fake.
• Restriction of the type of extension files being uploaded on the website is yet another method of security check.
• Renaming files is another way in which the program can be secured. This procedure involves the checking of double-barreld extensions like yourfile.php.gif.
• Changing the permission command for the upload folder so that files within it are not executable.
• All the alterations created by the user should be allowed only when they ‘Login’ into the database. On the other hand the owner of the site should always keep a close watch on all files being uploaded and then make them live.
Mysql Programming Security
Another aspect in php and mysql web development is the protection of the mysql libraries. Therefore, the most important aspect involved in protecting the mysql program is the security of the entire server host.
Securing MySQL is very essential for the smooth running of the website. This is based on Access Control Lists and SSL-encrypted connections, for protecting the php mysql web development program from random users visiting the website.
Some of the vital things to be considered for online site protection are:
• Accessing of the mysql database should not be allowed for any and everyone.
• Privileges to the users should always be accompanied with some restriction. If one can easily connect to the server without any ‘login’ then the security level code of the MySQL server should be rechecked.
• The MySQL database should be void of plain-text passwords. Use programs like MD5 (), SHA1(), or some hashing function for complete protection.
• Do not choose passwords from dictionaries, since they can be hacked easily. Use programs that break the passwords.
Therefore, the successful development of a website through php and mysql web development is complete only when the site owner consults a professional programmer. They expertise in the optimization of the MySql hosting database. This program is dynamic in nature and is an effective tool in the creation of browser-based applications.
Php – A First Look
PHP: Hypertext Processor is a server-side web programming language that blends seamlessly with HTML. PHP can run on both Unix and Windows servers, which makes it more accessible than its Windows counterpart, Active Server Pages (ASP). Most full-service web design firms will have at least one PHP guru.
PHP uses are widespread, and can include any kind of server functionality that takes user’s input and displays or manipulates the input. Some pertinent examples of such work are message boards, auction sites, shopping carts, and more. This synopsis is meant to serve only as a gateway to other works; although the main goal is to give a reader enough information so they can make educated decisions about what their web developer should do. For those looking to get into PHP, there are many free tutorials and primers out there:
http://www.4webhelp.net/tutorials/php/basics.php, is a pertinent example
PHP generally uses the mySQL database system. MySQL is a server-side system that is included on many Unix, and some Windows servers.
Once a user knows the basics of PHP and its capacities, he can work with plenty of open-source scripts. Without having to actually build a script from scratch, one can get a fully functional website with a custom design (assuming the designer has HTML/graphics knowledge). Two of the most popular open-source (free) scripts for PHP/mySQL are PHPBB and osCommerce. PHPBB is forum software that is fairly common. It has all the main features of a message board and can have mods (modules) added for more features. OsCommerce is a shopping cart script that has support for many payment gateways, including some free ones like Paypal. The great thing about scripts like these is that they have a full community of developers – both beginners and professionals – that are there to help with installation and modification.
However, if a user doesn’t feel that he’s ready to take the plunge and work with PHP code, most web design firms are more than willing to work with open-source scripts. Others even have their own pre-made, or can work from scratch for an upgraded fee. Sometimes, an open source script simply won’t suffice because a user needs something tailored to his needs. Larger-scale online business and e-treps require capabilities that may be out of the reach of osCommerce.
To conclude, PHP is a server-side scripting language that offers widespread capabilities for web developers looking to interact with their viewers. It may take years to master a technology like this, but there are plenty of great deals out there for pre-made scripts or from-scratch technologies. This story served as an introduction to PHP, later articles will go into further detail.
