In PHP: are single quotes safer than double quotes?
I am working on a textarea block on a PHTML page in Magento 2.
In order to generate line breaks using r and rn in the predefined content of the block, I need double quotes instead of single quotes.
Considered that PHP interpretes variables in a string with double quotes:
Is there any possible safety issue when using double quotes instead of single quotes in a textarea in PHP?
If there is a risk: what is the best/easiest way to sanitize the user input in the textblock when making use of double quotes?
php security reference magento2

Unless you are dynamically generating PHP from user input and then evaluating it, there is no risk from user input just because you use a double-quoted string literal.
Thanks. I am using the textarea in a custom contact form in Magento 2. Would you consider that dynamically generating PHP from user input and then evaluating it?

I agree that I should not have used the term "consider" as it refers to an opinion. Still, I am not sure about the user input risk using double quotes. That is why I am seeking advice from somebody who knows..
