Our next program will be a more complexed variable program, using a verse that is repeated two times. The song chosen for this task is "Do you want to know a secret" by The Beatles.
As we have noted when we wrote the Using a variable php program, a variable is a holder for information in a computer's memory.
Similar to the previous two programs, the PHP code uses the <? and ?> special tag. We then use a special technique provided by PHP when writing this program. We start by assigning a value to the $verse variable as shown below:
$verse = <<<HERE
The <<<HERE segment signifies that there is a multi-line string. Once the verse text is written, the ending phrase HERE; is placed on a line by itself.
As demonstrated in the previous programs, we used notepad a plain text editor and stored the program on our web server, "C:\Wampserver2\www."
The steps to writing a PHP program are outlined below:
1. Select and click "Start."
2. Select and click "All Programs."
3. Select and click "Accessories."
4. Select and click "Notepad."
5. Type the HTML and PHP exactly as shown below.

You'll never know how much I really care<br>
$verse = <<<HERE
Do you want to know a secret<br>
Do you promise not to tell, whoa oh, oh<br>
Let me whisper in your ear<br>
Say the words you long to hear<br>
I'm in love with you<br>
print "<h3>Verse 1:</h3>";
print "<h3>Verse 2:</h3>";
I've known the secret for a week or two<br>
Nobody knows, just we two<br>
print "<h3>Verse 3:</h3>";
6. Once you have type the entire program, Select "File," "Save As," and then go to the webroot of your server. For example, C:\Wampserver2\www. Type Filename, "listendoyou.php," and then Select "Save."
