PHP: how to get $ to print using echo

Question

I am very new to PHP and have difficulty finding this answer since $ denotes a variable in PHP. I am trying to repeat the total number of elements, for example:

echo "Your total is ${$total}"; 

The problem is that $ front forces it to do nothing. I tried making "$" but it prints '' around $. How to get $ to print before a variable?

Answer 1

If you use double quotes ("), you need to escape the $ character:

 echo "Your total is \${$total}"; 

Answer 2

Just use single quotes.

echo 'Your total is $' . $total;

Check out this article for more information on the differences between single and double quotes in PHP.

Answer 3

And last but not least:

 printf('Your total is $%.2f', $total); 

Answer 4

You need to avoid the dollar sign: echo "\$"; .

Answer 5

 echo "Your total is $" . $total; 

You do not need to use variable parsing in all possible situations. Very often it is much easier (to write and understand) when it is simply written as a string concatenation.
