session_regenerate_id(): 無法重新生成會話 id - 標頭已發送

Question

它正在輸出： session_regenerate_id(): 無法重新生成會話 ID - 標頭已發送

session_start();

session_regenerate_id();
$_SESSION['inside'] = TRUE;
$_SESSION['username'] = $GettedName;
$_SESSION['id'] = $ID;
$_SESSION['email'] = $sirname ;
$_SESSION['sirname '] = $sirname ;

Answer 1

會話已發送錯誤的原因很少。 請嘗試使用 ob_start();

ob_start();
session_start();
session_regenerate_id();
$_SESSION['inside'] = TRUE;
$_SESSION['username'] = $GettedName;
$_SESSION['id'] = $ID;
$_SESSION['email'] = $sirname;
$_SESSION['sirname '] = $sirname;

Answer 2

ob_clean();
ob_start();

在代碼的開頭並檢查會話數組中是否有空間，如下所示

$_SESSION['sirname '] = $sirname ;

應該

$_SESSION['sirname'] = $sirname ;

試試這個

ob_clean();
ob_start();
session_regenerate_id();
$_SESSION['inside'] = TRUE;
$_SESSION['username'] = $GettedName;
$_SESSION['id'] = $ID;
$_SESSION['email'] = $sirname;
$_SESSION['sirname'] = $sirname;
