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 "?>"

Yes, you are correct Joe. Would you like to make the change to the wording? Thanks. Chris Davenport 19:11, 28 July 2009 (UTC)

Not familiar with the detail of php (which is why I am here!) but...
Arrays
"print $my_guitar_heroes[2]; //Access the 2nd element"
To be a pedant - [2] accesses the third element.
While Loop
while ( $x <= 10 ) { print "$x<BR/>"; }
The while loop illustrated does not increment $x so it will never exit.
Thanks for a very useful intro - trying to understand how to modify a template without breaking the common structure, so there is amountain to climb!
