Wrapping vars in braces helps clarify the code, and can avoid problems like:
<?
$price = '44.99';
echo "Price: US$$priceeach"; // probably won't work
echo "Price: US${$price}each"; // will work for sure
echo "Price: US$" . $price . "each"; // will work, but not my pref
?>
I've also found it helps with things like:
<?
echo "<a href='{$_SERVER['PHP_SELF']}'>click</a>";
?>
... where normally the single quotes would cause confusion, or require the
href to be wrapped in escaped double quotes.
In otherwords, wrapping $vars in {braces} provides clarity to both the PHP
parser, and to the writer, IMHO.
