session_regenerate_id（）：无法重新生成会话ID-已发送的标头

Question

它正在输出：session_regenerate_id（）：无法重新生成会话ID-已发送的标头

session_start();

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

Answer 1

会话已发送错误的原因很少。请使用ob_start（）来查找；

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();

在代码开头，并检查会话数组中是否有空间，如下所示

$_SESSION['sirname '] = $sirname ;

应该是

$_SESSION['sirname'] = $sirname ;

尝试一下

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