Your Second Script

Your second script, as did the first, will generate the traditional "Hello, World!" greeting. However, this time you will use a combination of PHP along with HTML. Follow the simple steps below.

Type
```
cd
```
to get to your home directory.
Type
```
cd public_html
```
to descend into your web pages directory.
Create a new file called hello_world.php.

Type in the following lines:

<!-- helloworld.php
  This file illustrates how to embed PHP code inside HTML
-->
<html>
<head>
<title>PHP inside HTML: Hello World</title>
</head>
<body>
<?php
echo "<h1 align=\"center\">The Hello World Program Output</h1>\n";
// Print the message
echo "<p>Hello, World!\n";
?>
<body>
<html>

In your favorite web browser, type
```
http://localhost/~YOURID/helloworld.php
```
where YOURID is the user ID you have on the system.

Notes

<!-- is the HTML indicator for the start of a comment.
--> is the HTML indicator for the end of a comment.
// is the PHP indicator that the rest of the line is a comment.
Since quotes are used to surround a string which echo will print, the backslash (\), is used as a precedence code to indicate that the following " is actually a character to be printed (and not the closing quote). This is similar to typing two single quotes in a Pascal string to get ` to print.
<?php informs the server that the following is PHP code. ?> informs the server that it has reached the end of the PHP code. All other material not enclosed by <?php and ?> is treated as HTML code.
