Through this short article we will demonstrate how to post shoutout message to your Friendster account using PHP and curl. Shoutout in Friendster is just like status message in Facebook. Here is the code to post the shoutout to Friendster.

<?php
  // set friendster credentials
  $username = "your_friendster_username";
  $password = "your_friendster_password";
  $message = "Hi all, I update my shoutout using PHP and curl...";
 
  // login to friendster
  $curl = curl_init();
  curl_setopt($curl, CURLOPT_URL, "http://m.friendster.com/login/doLogin");
  curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
  curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($curl, CURLOPT_POST, 1);
  curl_setopt($curl, CURLOPT_POSTFIELDS, "btnLogIn=Log In&email=" . $username . "&password=" . $password);
  curl_setopt($curl, CURLOPT_ENCODING, "");
  curl_setopt($curl, CURLOPT_COOKIEJAR, getcwd() . '/cookies_friendster.cookie');
  $curlData = curl_exec($curl);
  curl_close($curl);
 
  // update your friendster shoutout
  $curl = curl_init();
  curl_setopt($curl, CURLOPT_URL, "http://m.friendster.com/hp/editshoutout");
  curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);

  curl_setopt($curl, CURLOPT_COOKIEJAR, getcwd() . '/cookies_friendster.cookie');
  $curlData = curl_exec($curl);
  curl_close($curl);
 
  echo "Done!";
?>

Pretty simple, because we just emulate login to Friendster mobile version and update the shoutout message.

USGS has earthquake feed is available on http://earthquake.usgs.gov/eqcenter/catalogs/eqs1day-M2.5.xml. We will feed this data and draw it into FusionCharts Free.

Since the data contains magnitude data and earthquake depth, then I choose to use Combination Charts (Column 2D + Line Dual Y) (FCF_MSColumn2DLineDY.swf). Why we use Dual Y Axis chart? Because we want to represent the earthquake magnitude on the primary Y axis and earthquake depth on secondary Y axis. We also utilizing prototype.js PeriodicalExecuter() class to make Ajax call to the earthquake data feed. By the time of this writing, we use FusionCharts Free v2.2.

Important Notes
We assume you already familiar with deploying the FusionCharts Free and have experience using prototype.js, since we don’t explain every details of the tools we used in this article. Please refer to FusionCharts Free documentation about deploying the chart and prototype.js documentation about the usage of the library.

Prepare the chart and other requirements
First you must copy several file needed on this project.
- You must copy FusionCharts.js to your web root folder.
- You must copy prototype.js to your web root folder.
- You must copy FCF_MSColumn2DLineDY.swf to your web root folder.

Create the chart web page
Here is the code of the chart web page.

			  method: 'get',
			  onSuccess: function(transport) {
			    updateChartXML('earthQuakeId', transport.responseText);
			  }
			});
	}, 20);
</script>

Save it as earthquake.php.

You can see on above code, the script will call ‘latest_earthquake_data.php’ on the first time and then will call the script again through Ajax call (using PeriodicalExecuter class on prototype.js) every 20 seconds. You can adjust the interval if you want.

Prepare the script to feed the USGS earthquake data
Now here is the data feeder code (on latest_earthquake_data.php). This is the heart of this application and will supply the data to the FusionCharts.

You can read the details of the SMTP protocol here. SMTP stands for Simple Mail Transfer Protocol. Created by Jonathan B Postel, the objective is simple, to transfer mail reliably and efficiently. The SMTP protocol still used today by many e-mail clients software.

Through this article, I will show you how to send simple e-mail using SMTP protocol. You will learn basic SMTP commands to send e-mail.

1. Open your command prompt window.

2. Type telnet [smtp host] [port 25], because I am using XL network, so I will use XL SMTP host. Their SMTP host is xlsmtp.xl.net.id. Standard port number for SMTP is 25. You can search your network SMTP host on the internet.

Connecting to XL SMTP host

Connecting to XL SMTP host

3. Type HELO or EHLO command. EHLO command is like HELO command but EHLO command will response with several SMTP abilities on that host.

Sending EHLO command

Sending EHLO command

4. Type MAIL FROM command. This command is to define the sender e-mail address.

Sending MAIL FROM command with my e-mail address as a sender address

Sending MAIL FROM command with my e-mail address as a sender address

5. Type RCPT TO command. This command is to define target or recipient e-mail address.

Send RCPT TO command

Send RCPT TO command

6. Type DATA command. DATA command is to start input envelope part and body message part of your e-mail. What is envelope part? For example the e-mail header message that contains From, To, Subject and so on is called an envelope part of your e-mail, then there is single blank line that seperate the envelope data with the body e-mail message. Please see the sample below. At the end, just type single dot (.) command on a single line to finish the DATA command transaction.

Type DATA command

Type DATA command

Type the details of envelope part and body message part

Type the details of envelope part and body message part

Send the single dot (.) to end the DATA command transaction

7. Type QUIT command to quit sending e-mail transaction and your message will be queued for delivery to the recipient address.

Simple isn’t? You can try yourself with your ISP SMTP server.

Now we will playing with real-world case. We will visualize the official earthquake data from U.S Geological Survey (USGS) into the chart using FusionCharts. I am using FusionCharts Developer licence in this case. USGS has earthquake feed on http://earthquake.usgs.gov/eqcenter/catalogs/eqs1day-M2.5.xml. We will feed this data and draw it into FusionCharts.

Since the data contains magnitude data and earthquake depth, then I choose to use Scroll Combination (Dual Y Axis) 2D chart (ScrollCombiDY2D.swf). Why we use Dual Y Axis chart? Because we want to represent the earthquake magnitude on the primary Y axis and earthquake depth on secondary Y axis. Because there are many data on the earthquake feed, so we use the scrolled version of the chart.

Many people using it to chat with friends over the world. Nowdays IRC is less popular than other services, such Yahoo! Messenger, Skype, Gtalk, Facebook Chat etc, but IRC still used on some community such as developer community. For example, CakePHP community often available on irc.freenode.net #cakephp, CodeIgniter also available on the same server at #codeigniter.

Now we will try to do fun things. Yes, we will simulate connection to IRC server not using IRC client software but only using Telnet. Again, this is for personal fun things. I just do it for remembering the past when learning the IRC protocol.

Let’s start baby
1. Define the IRC server to connect. I choose irc.freenode.net on port 6666 since it’s very popular IRC network now. Go to command prompt and type the following command.

1

telnet irc.freenode.net 6666
Connect to irc.freenode.net port 6666

Connect to irc.freenode.net port 6666

2. You will be connected to IRC server irc.freenode.net network. Now you must define your nickname. Type this command to define your nickname.

1

NICK sonyarianto
Define nickname

Define nickname

3. Now you must send the USER command. It is used in communication between servers to indicate new user arriving on IRC, since only after both USER and NICK have been received from a client does a user become registered. The syntax is like this “USER “. Just type like the following.

1

USER sonyarianto host server :Sony AK IRC Mania
Typing USER command to IRC

Typing USER command to IRC

4. You will get many lines on your screen, don’t worry, it’s called MOTD (Message Of The Day) string. Now you are already connected to irc.freenode.net IRC network.

5. Now we will simulate to join a IRC channel. I will join to #codeigniter channel. Type the following command to join a channel.

1

JOIN #codeigniter

6. Now you already joined to #codeigniter channel. There are many string on your screen, don’t worry, it’s a list of users that also connected to #codeigniter channel.

After join to #codeigniter channel

After join to #codeigniter channel

You can see on above screen shot, there are sonyarianto, bwoodall, techrush, Hutch[S] etc, it is users that connected to #codeigniter channel.

7. Now you can send message to #codeigniter with PRIVMSG command. Type the following command.

1

PRIVMSG #codeigniter :Hi everybody, how r u today?
Send command to channel with PRIVMSG

Send command to channel with PRIVMSG

8. The PRIVMSG command also can be used to send message to a user. The syntax is like this ‘PRIVMSG :‘. Let’s assume there user with nick ‘agus’ so you can type message privately to agus using this way.

1

PRIVMSG agus :Hello Agus, I'm here to chat with you.

9. That’s all. Now you have learned basic commands on IRC protocol. To quit from a channel you can use PART command.

1

PART #codeigniter

You will left from #codeigniter channel.

10. To quit from IRC network you can use QUIT command.

1

QUIT

That’s all, now I hope you will understand basic knowledge command about IRC protocol and from this point you can improve your knowledge if you want to create IRC application or IRC robot.

Now we will talking about utilizing the Zend Framework’s Zend_Gdata class to manipulate user account on your Google Apps account. Nowdays there many people or institutions using Google Apps as their e-mail solutions. If you are using Google Apps Premier Edition and Google Apps Education Edition you will have access to Google Provisioning API. To enable the API, log in to your admin account, and click the Users and groups tab. Then click the Settings subtab, select the checkbox to enable the Provisioning API and save your changes. (You will need to complete the steps for setting up Google Apps before you can log in to your admin account.)

What is actually Google Apps Provisioning API?
Google Apps allows website administrators to offer a variety of personalized and co-branded Google applications, such as Gmail. Google Apps Provisioning API enables application developers to programmatically enable access to these applications. Specifically, the API provides functions for creating, retrieving, updating and deleting user accounts, nicknames and email groups. You can access more information about Google Apps Provisioning API on their official documentation page.

Let’s start
Fortunately I have a Google Apps Partner Edition from the past days for one of my domain, mobitrek.com. So I will use this as our simulation to implement the Google Apps Provisioning API. Before using the Provisioning API, you will need an administrator username and password for your Google Apps domain.

We not cover all complicated things over the API, but will will show you some example to to simple task such as creating user. The complete reference already available on http://framework.zend.com/manual/en/zend.gdata.gapps.html and http://code.google.com/apis/apps/gdata_provisioning_api_v2.0_reference_php.html.

Authenticating to your Google Apps domain
Before you call some Google Apps Provisioning API, you have to do authentication process to your domain. Here is the way to do it.

  Zend_Loader::loadClass('Zend_Gdata_Gapps');
 
  // google apps credentials
  $email = "your_administrator_email_on_your_google_apps_domain"; // example sony@domain.com
  $password = "your_google_apps_domain_password";
 
  $domain = "your-domain.com";
 
  $client = Zend_Gdata_ClientLogin::getHttpClient($email, $password, Zend_Gdata_Gapps::AUTH_SERVICE_NAME);
  $service = new Zend_Gdata_Gapps($client, $domain);
?>

Now we will try to create e-mail account on your Google Apps domain.

  Zend_Loader::loadClass('Zend_Gdata_Gapps');
 
  // google apps credentials
  $email = "your_administrator_email_on_your_google_apps_domain"; // example sony@domain.com
  $password = "your_google_apps_domain_password";
 
  $domain = "your-domain.com";
 
  // do authenticate to Google Apps domain
  $client = Zend_Gdata_ClientLogin::getHttpClient($email, $password, Zend_Gdata_Gapps::AUTH_SERVICE_NAME);
  $service = new Zend_Gdata_Gapps($client, $domain);
 
  // create new user
  $username = "esa.ivani";
  $givenName = "Esa";
  $familyName = "Ivani";
  $password = "welcome";
 
  $service->createUser($username, $givenName, $familyName, $password, $passwordHashFunction = null, $quota = null);
 
  echo "done!";
?>

We create new user ‘esa.ivani’ on example above. We assume that user ‘esa.ivani’ is not exists yet. How to detect if user already exists during user creation process? It’s easy, there is methods for handling error for above condition. Here is the sample code again based on code above.

  Zend_Loader::loadClass('Zend_Gdata_Gapps');
 
  // google apps credentials
  $email = "your_administrator_email_on_your_google_apps_domain"; // example sony@domain.com
  $password = "your_google_apps_domain_password";
 
  $domain = "your-domain.com";
 
  // do authenticate to Google Apps domain
  $client = Zend_Gdata_ClientLogin::getHttpClient($email, $password, Zend_Gdata_Gapps::AUTH_SERVICE_NAME);
  $service = new Zend_Gdata_Gapps($client, $domain);
 
  // create new user
  $username = "esa.ivani";
  $givenName = "Esa";
  $familyName = "Ivani";
  $password = "welcome";
 
  try{
    $service->createUser($username, $givenName, $familyName, $password, $passwordHashFunction = null, $quota = null);
  } catch (Zend_Gdata_Gapps_ServiceException $e) {
    if ($e->hasError(Zend_Gdata_Gapps_Error::ENTITY_EXISTS)) {
      echo "User already exists!";
      exit;
    }
    else {
      foreach ($e->getErrors() as $error) {
        echo "Error encountered: {$error->getReason()} ({$error->getErrorCode()})\n";
      }
      exit();
    }
  }
 
  echo "done!";
?>

We put the ‘createUser’ method inside the ServiceException. The PHP client library will throw a ServiceException when it receives an error response from the Provisioning API. Other types of exceptions may also be thrown for other types of errors. To process or log a ServiceException, retrieve the error array by calling the $e->getErrors() method, then calling $error->getErrorCode() or $error->getReason() on each element of that array to determine the type of errors that the Provisioning API returned. The presence of individual error codes can also quickly be determined by calling $e->hasError($errorCode).

Retrieve User
You can call retrieveUser() method to get details about particular user. Here is the sample code.

  $user = $service->retrieveUser($username);
 
  echo  'Username: ' . $user->login->userName  . "<br/>";
  echo  'Given Name: ' . $user->name->givenName  . "<br/>";
  echo  'Family Name: ' . $user->name->familyName  . "<br/>";
  echo  'Suspended: ' . ($user->login->suspended ? 'Yes' : 'No') . "<br/>";

  echo 'Has Agreed To Terms: ' .
     ($user->login->agreedToTerms ? 'Yes' : 'No') . "<br/>";
?>

There are many methods you can utilize to access Google Apps Provisioning API. From creating user, update user, retrieve user, delete user, suspend user, restore suspend user and also nickname management. The point is, you can create your own email registration service with this API with provide seemless integration with your web application or service. Please read again the manual at the URLs below.

Yes, good question. Actually there is another way to achive this. You can use the ini_set() function to set the value on your PHP configuration option. Here is the sample of using ini_set() to change the value of ‘include_path’ on your PHP configuration.

What the hell is that? Well, it’s seems this feature is not important, but actually it will be useful if the member of the site was forgot their password. How to create a simple but quite good ‘forget password’ feature? As usual, we will need a scenario to reproduce our problem. But before we talk about the scenario, we will cover about our ‘forget password’ mechanism first.

1. Suppose someone has forgot the password on your site
2. We will provide her with forget password page
3. We ask her to input her username on that page
4. Your software will search the username on the database, if username found then send e-mail that associated with that username that contains the special URL to reset the password.
5. It’s clear that on point (4) above, we will provide the user to RESET the password, not to RETRIEVE the forgotten password.

Now we will create the user table that store the username and password.

CREATE TABLE IF NOT EXISTS tbl_users (
  id int(11) NOT NULL AUTO_INCREMENT,
  username varchar(50) DEFAULT NULL,
  password varchar(100) DEFAULT NULL,
  forget_pass_key varchar(50) DEFAULT NULL,
  email varchar(100) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=MyISAM  DEFAULT CHARSET=latin1 ;

Now we will add some data to that table.

INSERT INTO tbl_users (id, username, password, forget_pass_key, email) VALUES
(1, 'sonyak', 'c0b137fe2d792459f26ff763cce44574a5b5ab03', NULL, 'sony@sony-ak.com'),
(2, 'esaivani', 'c0b137fe2d792459f26ff763cce44574a5b5ab03', NULL, 'esa@sony-ak.com'),
(3, 'ingrid', 'c0b137fe2d792459f26ff763cce44574a5b5ab03', NULL, 'ingrid@anu.com');

You can see the above SQL statement, the password field is using SHA1 hash string. The actual password string is ‘welcome’.

Now we will create the forget password page.

Reset password page to input the new password from user

On the ‘reset_password.php’ above, we will ask the user to input the new password and will be processed by ‘p_reset_password.php’ script. Here is the code for ‘p_reset_password.php’ script.

You can see on script above, we do some checking before we update the password. If everything goess right, then the password will be successfuly updated with the new one. You still can improve and adjust the code above or even improve the mechanism with your own preference. There are many different implementation of ‘forget password’ or ‘lost password’ feature we already saw on many web sites.
