    Writing First PHP Script

                      The echo statement is used in a PHP script to display the output on the web page. It can be used
                      with or without parenthesis. Let us write a PHP script to display Hello World! message. Perform
                      the following steps to create the script:
                      Step  1   Open Notepad and type the following code:

                      <HTML>
                      <HEAD> <TITLE> First PHP Script </TITLE> </HEAD>
                      <BODY>

                      <?php

                      echo "Hello World!";
                      ?>
                      </BODY>

                      </HTML>

                      Step  2   Save the file with the Hello.php name under the C:\xampp\htdocs folder.
                      Running a Script

                      Perform the following steps to run a script:

                                                                   2  Type the following URL in the
                                 1  Open a Web browser..           Address bar: http://localhost/hello.php

                      The echo statement will display Hello World! on the web page. Note that every PHP statement
                      should be terminated with a semicolon. Ensure that the Apache HTTP Server should be running
                      before executing the script.

                      PHP KEYWORDS

                      PHP provides a set of keywords that are reserved words. They cannot be used as variable names,
                      class names or method names. Some of the keywords are as follows:

                       Abstract            And                 As                  Break               callable
                       Case                catch               class               clone               const
                       continue            declare             default             do                  echo
