I'm getting an error:

     syntax error, unexpected ')', expecting ']'  on line 7.

我试图更正之前的错误“PHP Fatal error: Call to undefined function session_is_registered()

Blockquote

    session_start();
        if(!isset($_SESSION['user'))
            session_register("user");
            $_SESSION['user'] = array();
        }
        if(!session_is_registered('cart')) {
            session_register("cart");
            $_SESSION['cart'] = array();
        }
        define("USERID", userId());

        if($secureMode == "ON" && $_SERVER['HTTPS'] != "on")
            die(header("Location: ".SELF));

        if($secureMode != "ON" && $_SERVER['HTTPS'] == "on")
            die(header("Location: ".SELF));

        if($_GET['f'] == "user") $_SESSION['filterUser'] = 1;
        elseif($_GET['f'] == "all") $_SESSION['filterUser'] = false;

        if($_SESSION['filterUser']) $sortBy = "byUser";
        else $sortBy = "byAll";

更新:PHP fatal error :在第 8 行调用未定义函数 session_register()

session_register("用户");

if(!isset($_SESSION['user'))
应该
if(!isset($_SESSION['user']))
注意右方括号。

您还需要一个 {之后。
