Correct PHP Session and variable syntax

Question

The following syntax is incorrect:

$_session['page'$numberpages]=$CurrentPage;

What is the correct syntax?

Answer 1

You probably want this:

$_SESSION['page'.$numberpages] = $CurrentPage;

• $_SESSION is a special superglobal variable and needs to be in uppercase.
• 'page'.$numberpages needs the string concatenation operator.

Answer 2

 $_SESSION['page' . $numberpages] = $CurrentPage;

Answer 3

You're missing a dot, a concatenation dot:

$_SESSION['page' . $numberpages]=$CurrentPage;

Or use double quotes:

$_SESSION["page$numberpages"]=$CurrentPage;

And, variable names are case-sensitive in PHP, unlike function names. So, it should be $_SESSION, instead of $_session.
