What is the advantage of not having the closing tag `?>` In the PHP class file?

Question

Possible duplicate:
PHP closing tag

I saw a lot of PHP class files that don't have a closure ?>, but instead:

<?php
class DataTypeLine extends DataType {
    ...
}
?>

they just have this:

<?php
class DataTypeLine extends DataType {
    ...
}

I also notice that when I create a new PHP file in Eclipse Helios , by default it has only the start tag <?php, but without the end of the tag ?> .

What is the advantage of missing a tag ?>?
