Using a String Variable

Again, your new script will generate the traditional "Hello, World!" greeting. However, this time you will introduce a string variable. Follow the simple steps below.

Get to the directory where you are storing your PHP code.

Create a new file called helloworld3.php so that it looks like the following code.

<?php
// PHP echoing "Hello World in HTML"
// Using a variable
// helloworld3.php
$title = "Hello World in HTML";
echo "<html>\n";
echo " <head>\n";
echo "  <title>" . $title . "</title>\n";
echo " </head>\n";
echo " <body>\n";
echo "  <p>Hello, World!</p>\n";
echo " </body>\n";
echo "</html>\n";
?>

In your favorite web browser, type
```
http://localhost/~YOURID/test_php/helloworld3.php
```
where YOURID is the user ID you have on the system.

Notes

All variables in PHP are begun with the $ character.
The = character is the assignment operator.
The line with the title tag illustrates how a string variable can be utilized along with the "dot" operator, which is used to concatenate strings. The following line would produce identical results:
echo " <title>$title</title>\n";
