If by "Whats the deal?" you want to know why they are used....

Both versions will work inside a double quotes string (or here doc).
Single quoted strings are not expanded.

If the variable reference is compound (e.g. $a[4], $this->var) then
braces are necessary.

[echo "<a href='www.mydomain.com'>$fred</a>";] is essentially the same
speed as [echo "<a href='www.mydomain.com'>{$fred}</a>";] while [echo
"<a href='www.mydomain.com'>".$fred."</a>"; ] is slower.

Leaving braces out when they are not necessary makes the code clearer.

If you mean "Why shouldn't I do it?"...

Its your code. <shrug>
