(once completed your pages should resemble assignment 3 example

Reading:

• WARNING: You cannot look at your PHP files or your pages that contain PHP from your hard drive unless you install PHP on your computer. You absolutely must upload your files to view them correctly. The class server does support PHP.
• See Appendix A in the text page 647 for instructions on installing PHP. This is not required. You can always upload your files to the server to test your PHP. Just remember, you must upload after each change to test. I cannot help you with PHP installation.
• On most servers, an html page that contains php will still render and process the php. However, our server was not set up that way. Since we still don't have everything set up the way I want them, I'm not going to ask for the change. Just name any page that contains php with the extension php.

Practice:

• Using PHP
  • Create an assignment3 folder (no spaces in the name, no uppercase) in your public_html folder.
  • helloWorld1.php Page
    • Open your template.htm page in your editor.
    • Save your template as helloWorld1.php in your assignment3 folder.
      • For pages that are really html pages that include a php block of code, you need all the doctype, head, body, etc.
      • For pages that are only php statements they will start with <?php and end with ?>
    • Add a PHP block that uses the echo statement to display "Hello World". (Just like in JavaScript, you must include the open and close p tags within the string so that your html page will validate after it renders. Remember, you have to upload then view in your browser to see if this works.)
    • Save your helloWorld1.php document.

• Creating an external PHP file (do not start with your template)
  • welcome.php Page
    • Create a php page with the following code (using your own name):

                        <?php
                        echo "<p>Welcome Judy Scholl </p>";
                        function help()
                        {
                          echo "<p>How can I help you?</p>";
                        }
                        ?>

    • Save the document as welcome.php.

• Including an external php file in your HTML (with the extension php) page.
  • helloWorld2.php Page
    • If necessary, open helloWorld1.php from your assignment3 folder in your editor.
    • Add the coding below your other php coding in your helloWorld.php page to include your external php page welcome.php.

                            <?php
                            include 'welcome.php';
                            help(); 
                            ?>

    • The include statement pulls the welcome.php external file into your HTML document at the location where you place your code. The statement help(); calls the function help() that was declared in your external page.
    • Save the document as helloWorld2.php.
