Example:
<?php $formElement->display()?>
Is this fine, or should I provide a ; ? Well I guess that the PHP interpreter is clever enough to see that the line is finished and the expression done because of the ?> at the end. Right?

4If I learned one thing, this is: Ask experts who know it better than what you believe to see. Might "work", but not be "good", under particular circumstances. – openfrog Jan 10 '10 at 21:44

4Even better than asking experts is to check with the Manual first ;) – Gordon Jan 10 '10 at 22:32

It is not required, but you should put it, as a good practice.
That way, the day you need to add another instruction after this one, it'll work fine.
And here is the manual's page that answers your question : Instruction separation (quoting, emphasis mine) :
As in C or Perl, PHP requires instructions to be terminated with a semicolon at the end of each statement.
The closing tag of a block of PHP code automatically implies a semicolon; you do not need to have a semicolon terminating the last line of a PHP block.
The closing tag for the block will include the immediately trailing newline if one is present.

If you run the code through the Tokenizer, PHP will not recognize the semicolon. See related answer here: http://stackoverflow.com/questions/2020445/what-does-mean-in-php/2020668#2020668 – Gordon Jan 10 '10 at 22:04

No, the closing ?> will automatically close the line.
From the PHP Docs:
The closing tag of a block of PHP code automatically implies a semicolon; you do not need to have a semicolon terminating the last line of a PHP block.

As you say, the PHP interpreter will cope as-is.
However, I'd say that adding the semicolon is probably slightly better practice, but that's just a personal coding preference.

Simple answer: yes. It's okay to only have one statement without a semicolon inside PHP tags.
