Variables in Double Quoted Strings
Would I use print "$a dollars" or "{$a} dollars" to print out the amount of dollars in this example?
✍: FYIcenter
In this example, "$a dollars" or "{$a} dollars" will print the same result.
But in other cases, you need to use curly braces to protect variable names. For example, for following PHP script will print different results:
<?php $sales = 7; echo "$sales000000 dollars\n"; echo "{$sales}000000 dollars\n"; ?>
