Question: Would I use print "$a dollars" or "{$a} dollars" to print out the amount of dollars in this example?Answer: In this example it wouldn't matter, since the variable is all by itself, but if you were to print something like "{$a},000,000 mln dollars", then you definitely need to use the braces. |
