Help breaking down a this php code

Hi All,

I having been getting some help with a custom store that I am building and have been given a piece of code by support that works but I do not understand how and would be grateful if someone could break it down for me.

.(isset($_SESSION['currencySymbol']))?$_SESSION['currencySymbol']:"$".

I understand the isset. So for me this statement says if session "currencySymbol" exists, but I do not know what the ? is for at the end as well as the :"$"

Hello,

The ? : style is a ternary operator which is meant to be shorthand for traditional if statements.

The code above is the same as:
if(isset($_SESSION['currencySymbol']):
    
else:
    $_SESSION['currencySymbol'] = "$";
endif;

Open in new window


So basically, if that SESSION variable is not set, then set it to "$".
