About "{" and "}". Sometimes PHP programmers need to use "{" and "}" to resolve ambiguity. Here is some examples. Variable Variables: <?php $foo = "test"; $$bar = "this is"; echo "${$bar} $foo"; // prints "this is test" ?> Note: it is the same as <?php echo "$test $foo"; ?> Array in string: <?php $arr[10][10][10] = "string"; echo "This is {$arr[10][10][10]}"; // prints "This is string" ?> Associative Array in string: <?php $arr['item'] = 'string'; echo "This is {$arr['item']}"; //prints "This is string". ?> --was-- About "{" and "}".
