PHP was introduced by  Rasmus Lerdorf in the year 1994, but people started using this year1995, after some time the second version was introduced in the mid-1995 this slowly and steadily PHP started taking its place and was used by 14000-15000 websites in the year 1996. The number of users increased on a continuous basis and in 1997 it reached almost 50000 people and that was the time when PHP3 or PHP version three was introduced. 

PHP is a programming language. This language is generally used for web development. It is popular because of its easy-to-use features. Many web developers also find it easy to learn.

The extension used for this language is .php. When PHP was initially introduced it was called an open-source programming language. 

It is an intermix of numerous databases like:

  1. MySQL

  2.  PostgreSQL

  3. Oracle

  4. Sybase

  5. Informix 

  6.  Microsoft SQL Server.

PHP is also used to execute some basic system functions, manage data and record fines, delete data, data sending via emails, it is also used to ciphertext. 

Let us begin with a simple illustration of the PHP scripting language.




      <title>Hello World</title>




      <?php echo “Hello, World!”;

$color = “red”;

Echo “My car is ” . $color . “<br>”;

ECHO “My house is ” . $COLOR . “<br>”;

echo “My boat is ” . $coLOR . “<br>”;?>



It will show the output as 

Hello, world!


Php is a sub structure of HTML, wordpress, XML, MVC,CMS

      <?php echo “Hello, World!”;?>

PHP variables start with $ sign and terminate with ; sign 

 These are some basic syntax used in the PHP language.

Variables in PHP 

  1. These variables are used as a vessel for containing data.

  2. Variable used this $ sign for the commencement and went around with the variable name. 

  3. Variable scope- it is that part of language which shows where to use these variables.

              These scopes are divided into three categories namely:

  •  Local – is placed inside the function and only be ingressed there.

  • Global – is placed outside the function and only be ingressed there. 

  •  Static – on the completion of a function some variables disappear on their own and if you don’t want them to disappear then we use static at the starting of that variable.

  Constants in PHP  

  • Constants in PHP are the same except for one thing that once placed it cannot be swapped. 

  • Constants use letters or underscore.

  • Generate PHP constant: for this, we use the define() sign, which contains value, name, and case sensitivity. 

  • Constant array: it can contain numerous terms.

  • Global constant: they can be used anywhere in the program.
