PHP会话将ttfb减慢至少30秒

Question

I encountered the following problem:

I have a very simple script which forwards the user to this login script via POST:

session_start();
$_SESSION["job"] = "admin";
$_SESSION["login"] = true;
$_SESSION["email"] = "[e-mail]";
$_SESSION["username"] = "example";
session_write_close(); # I added this because it was recommendet to solve my problem, which it unforunately doesn't do.
header("Location: ../home");

As soon as this script is executed everything is blocked which executes session_start(); in its script. The TTFB is always above 60s

The only fix is to restart apache via service apache2 restart every time.

My Apache2and PHP are clean installed today on an absolute fresh server, everything was configured according to the official instructions. Additionally I encounter this problem on every other server I ran my script on.

What could be a solution? I've searched the internet for days now...

Answer 1

As read from the above comments it seems like there is further code after the header statement since working with exit solves your issue. So that people crossing this post quickly see the solution I add this answer.

To avoid this unwanted behaviour it's a good habit to place a die or exit after the statement.
