RTFM -- this example taken from http://uk2.php.net/manual/en/language.types.string.php#language.types.string .parsing.simple illustrates the topic pretty well: $fruits = array('strawberry' => 'red', 'banana' => 'yellow'); // Works but note that this works differently outside string-quotes echo "A banana is $fruits[banana]."; // Works echo "A banana is {$fruits['banana']}."; // Works but PHP looks for a constant named banana first // as described below. echo "A banana is {$fruits[banana]}."; // Won't work, use braces. This results in a parse error. echo "A banana is $fruits['banana']."; // Works echo "A banana is " . $fruits['banana'] . "."; // Works echo "This square is $square->width meters broad."; // Won't work. For a solution, see the complex syntax. echo "This square is $square->width00 centimeters broad."; ?> For anything more complex, you should use the complex syntax. I wouldn't personally encourage the "... $fruits[banana] ..." style, but it's valid and works perfectly well. Cheers!
