- 3. History of PHP • PHP began in 1995 when Rasmus Lerdorf developed a Perl/CGI script toolset he called the Personal Home Page or PHP • PHP 2 released 1997 (PHP now stands for Hypertext Processor). • PHP3 released in 1998 (50,000 users) • PHP4 released in 2000 (3.6 million domains). PHP5.0.0 released July 13, 2004 (113 libraries>1,000 functions with extensive object-oriented programming) • PHP5.0.5 released Sept. 6, 2005 for maintenance and bug fixes
- 4. INTRODUCTION What is PHP? • PHP stands for PHP: Hypertext Preprocessor • 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
- 5. INTRODUCTION What is PHP File? • PHP files can contain text, HTML tags and scripts. • PHP files are returned to the browser as plain HTML. • PHP files have a file extension of ".php", ".php3", or ".phtml“. Where to Start? • To get access to a web server with PHP support, you can: • Install Apache, Wamp,Xamp on your own server, install PHP, and MySQL
- 6. What is MySQL ? • MySQL is a database server • MySQL is ideal for both small and large applications • MySQL supports standard SQL • MySQL compiles on a number of platforms • MySQL is free to download and use
- 7. WHAT DOES PHP CODE LOOK LIKE? • Structurally similar to C/C++ • Supports procedural and object-oriented paradigm (to some degree) • All PHP statements end with a semi-colon • Each PHP script must be enclosed in the reserved PHP tag <?php … ?>
- 8. Comments in PHP In PHP, we use // to make a single-line comment or /* and */ to make a large comment block.
- 9. VARIABLES IN PHP • Variables are used for storing a values, like text strings, numbers or arrays. • When a variable is set it can be used over and over again in your script All variables in PHP start with a $ sign symbol.
- 10. HOW TO SHOW OUTPUT IN PHP ? • The PHP command ‘echo’ is used to output the parameters passed to it • Syntax : <?php $txt=“Hello World”; echo $txt; ?> OUTPUT: Hello World
- 15. PHP FORMS AND USER INPUT • The PHP $_GET and $_POST variables are used to retrieve information from forms, like user input. • The $_GET variable is used to collect values from a form with method="get". • EXAMPLE: <form action="welcome.php" method=“get"> • The $_POST variable is used to collect values from a form with method="post". • EXAMPLE: <form action="welcome.php" method="post">
- 16. HTML • HTML stands for Hypertext Markup Language, which is the main programming structure for web pages and browser software. • When browser software accesses an HTML file it understands how to parse the document according to the file's extension.(.html - .txt - .php - .xml - .pdf - .doc - etc... ). • HTML provides us a means of laying out and structuring our web pages using paragraphs, images, lists, indents, boxes, tables, colors, padding, and many more data structuring methods common to most data processing systems.
- 17. Basic HTML Tags The Main Elements of an HTML Document <html> : Defines the beginning and end of an HTML document. It contains the <head>, <title>, and <body> <head> : Used to describe or modify the content in the document. The head element contains the <meta>, and <title> elements <title> : Displays a page title in the browser tab bars and bookmark lists. The title element should come directly after your <meta> tags in the document and also communicates to search engine indexing bots to some degree. <body> : Directly after the <head> element closes(</head>) we define our <body> element. This element contains everything that we want to display to the browser software. The body element can have attributes set in it to affect the entire document if the author so chooses.
- 18. Cascaded Style Sheet(CSS) CSS is used to separate presentation and style from document markup content. CSS stands for Cascading Style Sheets Styles define how to display HTML elements Styles were added to HTML 4.0 to solve a problem External Style Sheets can save a lot of work External Style Sheets are stored in CSS files
- 19. JavaScript JavaScript (not to be confused with Java) is a scripting language that is widely used by many developers that focus on website and web applications creation. What is JavaScript? JavaScript was designed to add interactivity to HTML pages JavaScript is a scripting language A scripting language is a lightweight programming language JavaScript is usually embedded directly into HTML pages JavaScript is an interpreted language (means that scripts execute without preliminary compilation) Everyone can use JavaScript without purchasing a license
- 20. PHP Database: MySQL • MySQL is the most popular open-source database system. • MySQL is a relational database management system (RDBMS) that runs as a server providing multi-user access to number of databases. • MySQL is currently the world’s most popular and widely used open source database technology and data storage system. MySQL offers great reliability and ease of use. It is free, and comes with free documentation as well as thousands of programmers that share their code that relates to communicating with a MySQL database. The MySQL development project has made its source code available under the terms of the GNU General Public License, as well as under a variety of proprietary agreements.
- 21. Connecting PHP to MySQL • Before we can access data in a database, we must open a connection to the MySQL server. • In PHP, this is done with the mysql_connect() function. • Syntax : • mysql_connect(host,username,password,dbname); Parameter Description host Optional. Either a host name or an IP address username Optional. The MySQL user name password Optional. The password to log in with dbname Optional. The default database to be used when performing queries
- 22. Other MySQL Commands • Mysql_close() : used to close an opened connection to database • Mysql_query() : sends the sql query through the specified connection string to database returns the result • Mysql__fetch_array() : fetches result in an array from the returned value from the query • Mysql_error() : returns current mysql error description
- 23. Other MySQL Commands • mysql_connect("localhost", "mysql_user", "mysql_password") or die("Could not connect: " . mysql_error()); mysql_select_db("mydb"); $result = mysql_query("SELECT id, name FROM mytable"); while ($row = mysql_fetch_array($result)) { printf("ID: %s Name: %s", $row[0], $row[1]); } mysql_free_result($result); mysql_close();
- 24. How it Work MySQL

- 38. Reasons for Choosing PHP 1. Easy to get started 2. Designed for the web 3. Free to use 4. Many successful websites run on PHP
- 39. PHP Drawbacks • PHP is a scripting language so it is slow (compared to C or C++) • PHP is a scripting language with dynamic typing so it may have more undiscovered errors at run-time than a staticly typed language such as Java, C++ or C# • PHP is an ugly/messy/uncool procedural language
- 40. CONCLUSION • It is easier to create websites in php as compared to other technologies. • We have created the website in php as php is easy to learn and runs efficiently on the server side. • Secondly , php is free to use and it is compatible with almost all the servers used today.
