the short answer is yes.
i think you can find a sufficient explanation here,
http://us.php.net/manual/en/language.types.string.php#language.types.string.pa rsing.simple
and here
http://us.php.net/manual/en/language.types.string.php#language.types.string.pa rsing.complex

ok. I got it.
actually, my question was about: these two examples

$fruits = array('strawberry' => 'red', 'banana' => 'yellow');
echo "A banana is {$fruits['banana']}.";
echo "A banana is " . $fruits['banana'] . ".";

are the same.

Though, learned few more other things too :D

Thanks guys.
