It's actually *not* recommended that you start PHP code by "<?php" and end with a "?>" tag. If you are embedding PHP code within HTML markup, you do need to use the closing tag or the file will not parse correctly. However, if the file ends with PHP code instead of HTML markup, it is actually preferred to leave off the final "?>"
I would change that to read "When embedding PHP code within HTML markup, use <?php to start your code and ?> to close it" -jlleblanc
Yes, you are correct Joe. Would you like to make the change to the wording? Thanks. Chris Davenport 19:11, 28 July 2009 (UTC)
"print $my_guitar_heroes; //Access the 2nd element"
To be a pedant -  accesses the third element.
The while loop illustrated does not increment $x so it will never exit.
