　　基于HTTP的Oracle登录

　　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");
$title="Login Instructions";
echo "
You are not authorized to enter the site
";
exit;
}
else
{
if (!($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;
}}
?>
