I need help with this php file, coding is so confusing to me. Please help!! Thank You!!

To create a script that contains two functions:

1. Create a new document in your text editor. Type the

declaration,

element, header information,

and

element. Use the strict DTD and Two Functions

as the content of the

element.

2. Add the following script section to the document body:

?>

3. Add the first function to the script section as follows. This

function writes a message to the screen using an argument

that will be passed to it from the calling statement.

function displayMessage($FirstMessage) {

echo "

$FirstMessage

";

}

4. Add the second function, which displays a second message, to

the end of the script section. In this case, the message (This

message was returned from a function.) is defined within the

function itself. The only purpose of this function is to return

the literal string to the calling statement.

function returnMessage() {

return "

This message was returned from a

function.

";

}

5. Add the following three statements to the end of the

script section. The first statement displays the text string

This message was displayed from a function. in the Web

browser. This statement does not receive a return value.

The second statement assigns the function call to a variable

named $ReturnValue, but does not send any arguments

to the function. The third statement writes the value of the

$ReturnValue variable to the screen.

displayMessage("This message was displayed from a

function.");

$ReturnValue = returnMessage();

echo $ReturnValue;

6. Save the document as TwoFunctions.php in the Chapter

directory for Chapter 2, and then upload the document to the

Web server.

7. Open the TwoFunctions.php file in your Web browser by

entering the following URL: http:///PHP_

Projects/Chapter.02/Chapter/TwoFunctions.php. You should

see the Web page shown in Figure 2-2.
