1F：→ JustGame: 猜測是 /share/HDA_DATA/.php_session 這個目錄不存在或 02/13 22:35
2F：→ JustGame: 權限問題。 02/13 22:35
4F：→ JustGame: 這樣就知道問題出在哪裡 02/13 22:37
我試著按你的方法叫出錯誤訊息
[/] # chmod 666 /share/HDA_DATA/.php_session
[/] # ls -la /share/HDA_DATA/.php_session
drw-rw-rw- 2 admin administ 4096 Feb 13 23:37 ./
drwxrwxrwx 33 admin administ 4096 Feb 11 15:53 ../
此時透過session01.php和session02.php新加入顯示錯誤程式:
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);
會回傳:
Warning: Unknown:
open(/share/HDA_DATA/.php_session/sess_da2519c8bbab51f839ca0b906a3f6386,
O_RDWR) failed: Permission denied (13) in Unknown on line 0
Warning: Unknown: Failed to write session data (files). Please verify that
the current setting of session.save_path is correct
(/share/HDA_DATA/.php_session) in Unknown on line 0
我再改權限為全部可讀可寫後
[/] # chmod 777 /share/HDA_DATA/.php_session
[/] # ls -la /share/HDA_DATA/.php_session
drwxrwxrwx 2 admin administ 4096 Feb 13 23:48 ./

發現session01.php和session02.php的錯誤訊息不見了，且有找到上述的Session檔案
但是瀏覽器的結果 IDX1 is: 和 IDX2 is:後面還是空值
代表session01.php即便已經建立session檔案但還是沒有把值傳到session02.php
請教如何解決? 感恩!!
