What is PHP?

PHP is a general-purpose server-side scripting language originally designed for web development to produce dynamic web pages. It is among one of the first developed server-side scripting languages to be embedded into an HTML source document, rather than calling an external file to process data. Ultimately, the code is interpreted by a web server with a PHP processor module which generates the resulting web page. It also has evolved to include a command-line interface capability and can be used in standalone graphical applications. PHP can be deployed on most web servers and also as a standalone shellon almost every operating system and platform free of charge. A competitor to Microsoft's Active Server Pages (ASP) server-side script engine and similar languages, PHP is installed on more than 20 million websites and 1 million web servers.

My SQL

MySQL is a relational database management system that runs as a server providing multi-user access to a number of databases. TheSQL phrase stands for Structured Query Language.

Free-software-open source projects that require a full-featured database management system often use MySQL. MySQL is a popular choice of database for use in web applications, and is a central component of the widely used LAMP web application software stack-LAMP is an acronym for "Linux, Apache, MySQL, Perl/PHP/Python".

MySQL is an open source database management system and is used in some of the most frequently visited websites on the Internet, including Flickr, Nokia.com, YouTube and as previously mentioned, Wikipedia, Google, Facebook and Twitter.

Why PHP/My SQL?

There are more then 200 companies in India who hire fresh graduates for web development using php and My sql. Normally companies have to give 2-3 months of full time training in php and mysql to new hires. This course provides this real life training for web development before graduates join a company.

Scope of PHP/My Sql

• Website designing
• Web applications development
• Web hosting,
• Web maintenance

Eligibility

Any undergraduate can learn PHP/My Sql. Only requirement is that students have a strong desire to have a career as web developer and be willing to work real hard in learning and doing all assignments.

1.PHP INTRODUCTION

2.PHP started out as a small open source project that evolved as more and more people found out how useful it was. Rasmus Lerdorf unleashed the first version of PHP way back in 1994.
PHP is a recursive acronym for "PHP: Hypertext Preprocessor".
PHP is a server side scripting language that is embedded in HTML. It is used to manage dynamic content, databases, session tracking, even build entire e-commerce sites.
It is integrated with a number of popular databases, including MySQL, PostgreSQL, Oracle, Sybase, Informix, and Microsoft SQL Server.

3.PHP is pleasingly zippy in its execution, especially when compiled as an Apache module on the Unix side. The MySQL server, once started, executes even very complex queries with huge result sets in record-setting time.
PHP supports a large number of major protocols such as POP3, IMAP, and LDAP. PHP4 added support for Java and distributed object architectures (COM and CORBA), making n-tier development a possibility for the first time.
PHP is forgiving: PHP language tries to be as forgiving as possible.
PHP Syntax is C-Like.

4.Common uses of PHP:
PHP performs system functions, i.e. from files on a system it can create, open, read, write, and close them.
PHP can handle forms, i.e. gather data from files, save data to a file, thru email you can send data, return data to the user.
You add, delete, modify elements within your database thru PHP.
Access cookies variables and set cookies.
Using PHP, you can restrict users to access some pages of your website.
It can encrypt data.

5.Characteristics of PHP
Five important characteristics make PHP's practical nature possible:
Simplicity
Efficiency
Security
Flexibility
Familiarity

6."Hello World" Script in PHP:
To get a feel for PHP, first start with simple PHP scripts. Since "Hello, World!" is an essential!" script.
As mentioned earlier example, first we will create a friendly little "Hello, World, PHP is embedded in HTML. That means that in amongst your normal HTML (or XHTML if you're cutting-edge) you'll have PHP statements like this:





7.It will produce following result:
Hello, World!
If you examine the HTML output of the above example, you'll notice that the PHP code is not present in the file sent from the server to your Web browser. All of the PHP present in the Web page is processed and stripped from the page; the only thing returned to the client from the Web server is pure HTML output.
All PHP code must be included inside one of the three special markup tags ate are recognised by the PHP Parser.

8. 


Most common tag is the and we will also use same tag in our tutorial.
From the next chapter we will start with PHP Environment Setup on your machine and then we will dig out almost all concepts related to PHP to make you comfortable with the PHP language.
