A Possible Solve to Cookie Issues in Google Chrome (setcookie) (no replies)

Hsinping — Mon, 19 Sep 2011 01:53:32 +0800

A quick suggestion, if you encountered problems setting cookies in Google Chrome, is:

Change your original setting for subdomains

setcookie('session',      $session_key, $timeout, '/', '.domain.com' );

To

setcookie('session',      $session_key, $timeout, '/');

This could make things easier.

My personal experience is, HOW YOU CREATE A COOKIE IS THE WAY YOU DELETE THE COOKIE.

(If you set the cookie in NULL domain setting, you should use NULL domain to delete it.)

And, use the embedded Chrome tool (F12->Recources->Cookies) to check your cookies. I suggest to check if the cookies are the same in www.domain.com and domain.com (or xxx.domain.com). In the cases I encountered, they were simply DIFFERENT.

--

My scenario is making some changes in the session/login management (for the cross-domain stuff). Originally, I use the same setcookie setting in session restore and session create, like

setcookie('session', $session_key, $timeout, '/', '.domain.com' );

But, I changed the setting in session restore to

setcookie('session', $session_key, $timeout, '/')

Any things go wrong after that.

If my memory and interpretation are right, I guess the cookies set in NULL domain are SUPERIOR than those set in other domain settings. So once you set a cookie in NULL domain, you cannot delete/modify the cookie in other means.

If you set different cookies in .domain.com and domain.com (I main NULL), only the cookie set in NULL domain takes effect in domain.com. The one set in .domain.com (only) work in www.doamin.com.

So in my case, I set cookie in NULL domain in LOGIN (session create) and set in .domain.com in SESSION RESTROE. This (hoplefully) can make cookies work fine in all scenarios.

以PHP Script查詢 IP 地址對應之相關資訊(國家、城市、ISP、Domain Name等) (no replies)

HP — Sat, 17 Oct 2009 22:14:57 +0800

把下段 PHP 程式碼加入 php script 就可以得到 IP Address 相對應的資訊。




[PHP]


　$country = file_get_contents('http://api.hostip.info/country.php?ip='.$_SERVER['REMOTE_ADDR'];


　echo $country;


[/PHP]

基本原理就是以 HTTP URL (GET) 的方式

http://api.hostip.info/country.php?ip=140.112.41.70

取回 IP-to-Country 的資訊，再 echo 出來。

(請注意：本頁介紹的作法本為以下的 PHP 程式碼，但以下利用的網址 http://www.ipmango.com/api.php 似已不能使用。 2009.11.04)




$ip = '59.32.28.65';


$url = "http://www.ipmango.com/api.php?ip=".$ip;


$xml = simplexml_load_file($url);


echo "IP address : {$xml->ipaddress} \n";


echo "City : {$xml->city} \n";


echo "Region : {$xml->region} \n";


echo "Country Name : {$xml->countryname} \n";


echo "Latitude : {$xml->latitude} \n";


echo "Longitude : {$xml->longitude} \n";

「日本偶像劇場」算是個日劇大站，在 alexa 的排名目前(2009.08.31) 排第 27,280 名，在台灣排第 382 名。

站長在該站的精華中放了他從 2001 年一路以來在 PHP 程式撰寫上所用到的工具以及一些心得，我覺得很多都非常實用，和大家分享：
