php5.3 does not support session_register(). What should I do if this function is enabled?

// Fix for removed Session functions
function fix_session_register(){
function session_register(){
$args = func_get_args();
foreach ($args as $key){
$_SESSION [$key]=$GLOBALS[$key];
}
}
function session_is_registered($key){
return isset($_SESSION[$key]);
}
function session_unregister($key){
unset($ _SESSION[$key]);
}
}
if (!function_exists('session_register')) fix_session_register();
?>

I found another method, just put: session_register( “abc” ); Change to $_SESSION['abc'] = null; That’s it

Changes in session in php5.3 (bbs.it-home.org Script School) When running the code in the book in php5.3, you will get the following prompt: Function session_is_registered() is deprecated in Function session_register() is deprecated in That is to say, these two functions are deprecated and deprecated.

The following is the code from the official PHP manual. The comments section has stated that session_register() is deprecated.

// Use of session_register() is deprecated
$barney = "A big purple dinosaur.";
session_register("barney");
// Use of $_SESSION is preferred, as of PHP 4.1.0 "] = "He's got square pants.";
?>



Copy the code

Warning: This function is deprecated in php5.3 and has been removed in php5.4. If $_SESSION (or $HTTP_SESSION_VARS for PHP 4.0.6 or less) is used, use isset() to check a variable is registered in $_SESSION.

Tips: If $_SESSION is used, use the isset() function to check. If you are using $_SESSION (or $HTTP_SESSION_VARS), do not use session_register(), session_is_registered() and session_unregister().
