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
