I had previously installed php-4.3.9 and apache-2.0.49 on my solaris9
server and written a php script for user login, it ran well until
today...:-(
today for some reasons I upgraded php to php-5.1.2, complied as
apache's DSO module, and I found the script couldn't work when being
accessed by IE. I didn't know why...It seemed php script hadn't
transfered variables submmitted by web form to itself...now the
following is my script:
<?php
if ($queryflag == 1) {
$ybn="admin";
$ybp="111";
$ybusername=$_POST["username"];
$ybuserpwd=$_POST["password"];
if ($ybusername==$ybn AND $ybuserpwd==$ybp){
session_start();
$_SESSION["admin"]=true;
header("location: testtest.php");
} else {
echo <<<EOM
