＃実際試してみたテストスクリプトをそのまま書いてほしかった。^^;)

手元の環境では、MTさんが期待するどおりの動きになりました。
redhat linux9、php4.3.3 です。
とりあえず結果だけ。




テストスクリプト： test.php
-------------------------
<?php
session_start();
echo "#1 = " . session_id() . "<br>" ;    // #1
session_regenerate_id();
echo "#2 = " . session_id() . "<br>" ;     // #2
echo "<a href=test.php>リロードしてみよう!</a><br>";
echo "<br>";
//session設定の出力
echo "<pre>";
print_r(ini_get_all("session"));
echo "<pre>";
?> 
-------------------------

テスト方法： (1)test.phpにアクセス。
             (2)リロードしよう！をクリックしてもう一度アクセス

-------------------------
(1)をやった結果↓
-------------------------
#1 = d3f05a709b9fb302cf0c76d939d5009e
#2 = 3922fdb5be7a7117648e12e025d6fb86
リロードしてみよう!

-------------------------
(2)をやった結果↓
-------------------------
#1 = 3922fdb5be7a7117648e12e025d6fb86
#2 = 86a787bc9b85bf2117edc8b15042561e
リロードしてみよう!
