Facebook announced in their road-map about some major changes in the late 2009. Some of those changes now activated in facebook.  One of these important changes is to deprecate feed publish and replace it with stream publish.

I support it and like it. Because stream publishing is much easier and simple than feed publishing. This is a technical issue. So if you didn’t already change your feed publishing method to stream publish method, then you should do the change right now. Otherwise the wall post publish box will not work in your facebook or facebook connect application at anytime.

Basically I’m mainly php base web application developer. But I have  much interest in ActionScript project. Sometimes when I get opportunity I work on it. Someday ago, I was assigned in a project, where I’ve to develop a Flash Widget using ActionScript 3.0 and php. This widget will be use mainly for facebook page.

So shortly the project requirements are:

1. Develop a dynamic flash widget using ActionScript 3.0
2. Communication between ActionScript and PHP API
3. This widget should be working on any facebook page

To develop this project I’ve learned a new library called amfphp. Using this library its much easier and practical to communicate between ActionScript and php. In this article, I’ll show how to use amfphp and develop a dynamic flash widget.

If you’re a programmer and blog writer and like wordpress for your blog then you may need to modify some common functionality of your blog template. I’m not a professional wordpress template creator but sometimes I’ve to work to modify my blogs and some other blogs.

To modify existing wordpress template you have to know some common functions, rules of wordpress blog publishing application. And I found a cheat sheet that is very handy and helpful for this purpose. The cheat sheet is developed by Ekin Ertaç and you may also download the cheat sheet from here.

Sometimes clients want that the information they collected from the user should be encrypted and stored in database. Data encryption and decryption is a common technique for secured data. In this article I’ll show how could you use mysql’s built in function to encrypt and decrypt data.

Suppose you’ve a table where you want to encrypt user’s name & address. So look below the structure of the table. In this table we will store name and address as encrypted.

CREATE  TABLE `user` (
`id` BIGINT UNSIGNED NOT NULL AUTO_INCREMENT ,
`first_name` VARBINARY(100) NULL ,
`address` VARBINARY(200) NOT NULL ,
PRIMARY KEY (`id`)
ENGINE = InnoDB
DEFAULT CHARACTER SET = utf8
COLLATE = utf8_general_ci

You may be expected the table structure should be:

CREATE  TABLE `user` (
`id` BIGINT UNSIGNED NOT NULL AUTO_INCREMENT ,
`first_name` VARCHAR(50) NULL ,
`address` VARCHAR(100) NOT NULL ,
PRIMARY KEY (`id`)
ENGINE = InnoDB
DEFAULT CHARACTER SET = utf8
COLLATE = utf8_general_ci

If you have blog or website where you placed your email address, you may notice that there might be many spam emails send to your email address. This is because spammer scour the web to harvest email addresses. So to prevent this problem you can use obfuscated email address. Here I am showing a simple hack to solve this problem.

<?php
     $link = 'mailto:' . 'awoman@gmail.com';
     $coded = "";
     for ($i=0; $i<strlen($link); $i++){
         $coded .= "&#" . ord($link[$i]) . ";";
     }
?>

<a href="<?=$coded?>">Email Awoman</a>

In browser normal user will show simple html link like: Email Awoman but if you see the view source you ‘ll see

<a href="&#109;&#97;&#105;&#108;&#116;&#111;&#58;&#97;&#119;&#111;&#109;&#97;&#110;&#64;&#103;&#109;&#97;&#105;&#108;&#46;&#99;&#111;&#109;">Email Awoman</a>

The code is very simple. Using email address, create a mailto link and then loop though the characters by replacing each character with ASCII equivalent.
