No, because eval(), when passed string $str, effectively does this
silently:
$str = "<?php " . $str . " ?>";
and then passes $str to the PHP interpreter.
Which is, in most cases, what you want, because you want to evaluate PHP
code.
However, if eval() is the answer, you're probably asking the wrong
question. You should take a hard look at your code and think of a better
way to do what you need to do.
I can assure you one does exist, but with your example it's fairly
obvious, so you'd need to explain better what you're trying to do before
I could help you.
