将以下代码加在PHP页面代码之前以确认Oracle登录。注意你必须正确设定$ SID 。
if(!isset($PHP_AUTH_USER))

Header("WWW-authenticate: basic realm=\"$SID\"");
Header("HTTP/1.0 401 Unauthorized");
$title="Login Instructions";
echo "
You are not authorized to enter the site
\n";
exit;
}
else
{
if (!($conn=ora_logon("$PHP_AUTH_USER@$SID",$PHP_AUTH_PW)))
{
Header("WWW-authenticate: basic realm=\"$SID\"");
Header("HTTP/1.0 401 Unauthorized");
$title="Login Instructions";
echo "
You are not authorised to enter the site

exit;
}
