This is an example of an escape slash: "do you see the quotes" "Double quotes" vs 'single quotes' Double quotes are escaped using the "\" symbol prepended to the quotation mark such as \", and so are single quotes: \' You may use double quotes (") inside single quotes without using an escape character
$var = "variable 1" $var = "variable 1"
variable 1, variable 2 This is how you concatenate variables (after they are assigned): "$var1 . $var2"
