Question

I was asked in my interview question there is a convenient PHP function you can save a data without saving into the database for later use as of PHP 5.3 and I couldn’t answer this question.

Can anyone help me find out what that is?

Answer 1

You can save data to a lot of places. The most obvious is probably:

setcookie("MyCookie", $value, time()+3600, "/", ".example.com", 0); 

or

session_start();
$_SESSION['somekey'] = $someval;
