Why Trim function saves money

The answer simply: because it saves developer’s time.

In one of the php/Mysql websites I faced a problem with the sort order of some multilingual data. Usually when someone sort order such column, they get the English text first then the other languages like Arabic:

English text 1

English text 2

نص عربي 1

نص عربي 2

But what I have got was something like:

نص عربي 2

English text 2

English text 1

نص عربي 1

Actually some previous transportation processes of the database as well the high distortion of the sorted data made me thought that I have an encoding problem.

After 3 hours of work, trying to check the original encoding of data, I suddenly found that the web admin enters white spaces at the beginning of the entry very frequently. Although this made me smiling, as it saved me from falling in the hell of double-encoding problems, it pushed me to put a new ‘Must’ on my programming practices rules list.

The rule is the use of trim() function wherever the user has to enter data.

Fixing CPanel problem in redirecting domains to a URL friendly website

On one of the websites on an Apache server, I wanted to redirect two additional domain names to the main one, while using rewriting engine for URL friendly feature. I tried to use for that  the Redirect tool of CPanel with the Wild Card Redirect check. But like anything in a developer’s working life, it doesn’t work as one needs. The two domains didn’t work, with a “Server Not Found” error.

Back to the .htaccess file that the Cpanel modified I have found that the redirecting code is inserted after my friendly URL code:

RewriteEngine on
#URL Friendly
RewriteRule ^js/ - [L]
RewriteRule !\.(js|css|htm|gif|jpg|png)$ index.php

#Redirecting first domain
RewriteCond %{HTTP_HOST} ^firstDomaing.com$ [OR]
RewriteCond %{HTTP_HOST} ^www.firstDomain.com$
RewriteRule ^(.*)$ "http\:\/\/www\.targetDomain\.com$1" [R=301,L]

#Redirecting second domain
RewriteCond %{HTTP_HOST} ^secondDomain.net$ [OR]
RewriteCond %{HTTP_HOST} ^www.secondDomain.net$
RewriteRule ^(.*)$ "http\:\/\/www\.targetDomain\.com$1" [R=301,L]

Putting the URL friendly code after the redirecting code solved the problem. But wait, it still gives the “Server Not found” error when referring to a sub-directory at one of the redirected domains. To fix this I just needed to add \/? at the beginning of the redirecting RewriteRule so that it redirects the sub-directory to the root directory of the target domain.

But what if I need to redirect a sub-directory of the redirected domain to the same path at the target domain. To do it, I replaced $1 with %{REQUEST_URI} at the end of the same line. And with some refinement, I’ve got the code working properly:

RewriteEngine on

#Redirecting domains
RewriteCond %{HTTP_HOST} ^firstDomaing.com$ [OR]
RewriteCond %{HTTP_HOST} ^www.firstDomain.com$ [OR]
RewriteCond %{HTTP_HOST} ^secondDomain.net$ [OR]
RewriteCond %{HTTP_HOST} ^www.secondDomain.net$
RewriteRule ^\/?(.*)$ "http\:\/\/www\.targetDomain\.com%{REQUEST_URI}" [R=301,L]

#URL Friendly
RewriteRule ^js/ - [L]
RewriteRule !\.(js|css|htm|gif|jpg|png)$ index.php

RSS Feeds in Zend Framework

This example shows how to output an RSS feed using Zend_Feed component. The example supposes that you have a News class that extends Zend_Db_Table class in your models and you included the Zend_Feed component in your Zend Framework library.

class NewsController extends Zend_Controller_Action
{

function rssAction()
{

$table = new News();
//Get the last 10 news.
$rows = $table->fetchAll(null,”sort_order”,10);
//Create an array for our feed
$rss = array();

//Seting up the head information of the rss feed
$rss['title']      = “RSS Title Here”;
$rss['link']       = ‘http://www.my-domain.com';
$rss['published']     = time(); //Set the published date to now
$rss['charset']       = ‘utf-8′;
$rss['language']     = ‘ar-sa'; //for Arabic language
$rss['logo'] = “http://path/to/logo.gif”;
$rss['entries']       = array();//Which holds the actual news items

//Looping through the news to add them to the ‘entries’ array.

foreach($rows as $row){

$entry = array(); //Container for the entry before we add it on
$entry['title']     = $row->news_title; //The title of the news
$entry['link']         = “http://url/of/the/news/details/page”;
$entry['description']     = $row->news_brief; //a brief of the news
$entry['content']     = $row->news_details; //details of the news

$rss['entries'][]     = $entry;

}

$rssFeedFromArray = Zend_Feed::importBuilder(new Zend_Feed_Builder($rss), ‘rss’);

//disabling the layout
$this->getHelper(‘layout’)->disableLayout();

//printing the rss feed to standard output
print $rssFeedFromArray->saveXML();

//sending the HTTP headers and output the rss feed
$rssFeedFromArray->send();

}

}

What to call Twishort Twitter Service, Microblogging or Blogging?

Before closing my laptop to go bed, I’ve got a mention on twitter says “@samer_baydoun use new service http://twishort.com when 140 characters just isn’t enough. ;). I hurried to try it.

I found a twitter service that’s all about cuting the long post to the allowed limit and automatically posting it to Twitter with a link.  Following that link will show the whole post at Twishort page.

On Twishort website they present the service as:

“We really love Twitter for the limit of 140 characters. But sometimes there is a need to give a long answer, clarify challenging question, quote somebody’s words, etc. There are good thoughts, but not as meaningful for the blog, or just thoughts, for which 140 characters is not enough.”

But this way Twitter will play the role of chat/IM, which is away from its concept. So is Twishort seeing twitter as an IM client that needs help?

From another perspective, Twishort is trying to make micro posts longer while blogging is trending more towards microblogging, so what kind of trend is it? are we getting to milliblogging?

I am wondering about the future of this twitter service, and will be wondering more if it succeeded.

Internet Usage Penetration

The following chart shows that the UAE has the highest percentage of population in using Internet, followed by Bahrain and Qatar:

The highest growth online

Even being at the bottom of the Penetration list, Somalia has the highest growth by achieving 50,900% (from 200 users to 100,000 in about 9 years), followed by Sudan and Syria:

Still wondering how much these numbers are accurate, but it may give an overview of the situation in our Arab world.

OOP in PHP and Performance issues

When began with PHP, I used to write quick scripts, procedural, which served very well the small projects. But when uses OOP designs with PHP, I noticed the BIG difference in performance which went bad with the OOP.

PHP was not designed to be an Object Oriented Programming language, although there are very respectable attempts to make it so. I just thought about the future of the Object Oriented Design with the PHP, which is narrow in my opinion.

So why programmers should use PHP for OO designs while there are other languages such as Java?
