PHP tags usage

Use full PHP tags

Write:

<?php print $foo; ?>

Don't write:

<? print $foo; ?>

Semicolons
Write:

<?php print $foo; ?>

Don't write:

<?php print $foo ?>

No closing tags
When writing a module or customizing your theme template.php, don't use PHP closing tag ?>.

Notice that at the bottom of the following snippet, there is no PHP closing:

<?php

// Your file starts here

function phptemplate_foo() {

  return $bar;

}

// Your file ends here

// Don't add PHP closing tag

By doing this you prevent PHP interpreter to stop and restart on the next source code file. This mean better performance.
