- Runs most efficiently on an Apache server, but it can also run on IIS.
- An open-source and cross-platform language.
- Scripts are executed on the server.

History of PHP
PHP was originally created by a developer named Rasmus Lerdorf way back in 1994. It is the successor of product name PHP/FI.
Later on, in 1997 a stable version of PHP was released, that was PHP 2.0.
PHP 3.0 was introduced in 1998 and PHP 4 was introduced in 1999 and released in 2000.
PHP 5 was released in July 2004.
To start learning PHP You should know
This tutorial is developed for beginners who are completely unaware of the PHP concept and its powers. But one has basic knowledge about computer programming and its procedures.
Most Popular PHP Frameworks/CMS
PHP frameworks are built on an architecture that simplifies the process of building a complex application within a short period of time.
Here are some of the most popular PHP frameworks.
Here are some of the most popular PHP Content Management Systems.
Characteristics of PHP:
Five important characteristics :
Available for UNIX, MICROSOFT WINDOWS, MAC OS, and OS/2. PHP Programs are portable between platforms.
As a result, an application developed on, say, Windows will typically run on UNIX without any significant issues.
What actually is a PHP file?
abc.php – A file is a webpage that contains PHP (Hypertext Preprocessor) code. It may include PHP functions that can process online forms, get the date and time, or access information from a database, such as a MySQL database.
index.php – Often the default file to be loaded when a client Web browser requests a directory from a PHP-enabled Web server. For example, if http://phptest.com/ is requested, http://phptest.com/index.php is loaded.
How PHP works? Server, Clients and the Preprocessor communications
PHP as an Open source
PHP is an open source project – the language is developed by a worldwide team of volunteers who make its source code freely available on the Web, and it may be used without payment of licensing fees or investments in expensive hardware or software.
This reduces software development costs without affecting either flexibility or reliability. The open-source nature of the code further means that any developer, anywhere, can inspect the code tree, spit errors, and suggest possible fixes, this produces a stable, robust product wherein bugs, once discovered, are rapidly resolved – sometimes within a few hours of discovery.
First of all, let’s get started to our first tutorial with an example:
PHP Hello World Program
<html> <head> <title>try to program</title> </head> <body> <?php echo "Hello, World!";?> </body> </html>
<?php echo "Hello, World!";?>
This statement is the main syntax. furthermore, we’ll get through this syntax later.
Some real-world practice of PHP language
Have you seen this record form?
Filling all the information of Name, Salary, Designation & id we can insert our data in the database.
By clicking on CLICK HERE we can retrieve all the records stored in the database.
Now check this database table:
Look at this table, it is retrieving data (i.e. read, edit & delete )from the database by the help of PHP.
After learning these PHP programming tutorials, you will be able to integrate PHP as given above figures.
