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. -ll ____________________________________________________________________________________ Be a better friend, newshound, and know-it-all with Yahoo!
