After the addition: Later I added captcha to give the form more protection and it looks like this:

I give here only the images of how it will look after building an Login and Registration application using CodeIgniter Framework. When you register it will check whether username is available or not?

OOP in PHP

sanjibsinha — Tue, 24 May 2011 14:39:55 +0000

There is a very close similarity between ASP.NET and PHP OOP concept.
Whenever you call a method through object in ASP.NET it looks like this object.SomeMethod();
And in PHP it looks like object->SomeMethod();
Moreover there are many help from PHP in-built classes from PHP 5 onwards that was not available in PHP 4+.

Well, I’d like to write about this in INDIAN context. That is, I presume, you are about to start your journey as a web developer in India, and thinking about learning a web language. Now, keeping this condition in mind, what you’ll do? What will you learn first? And why this but not that?
I’ll keep writing it in several parts. Because I have not enough time and bandwidth in my data card to keep going on for a long journey, but I promise I’d keep it as short as possible.
Before starting I’d apologize for not including Python, Java or Rubi on Rails in my discussion mainly for two reasons.
1) I don’t know them.
2) For dynamic web site, the competition is fierce between these two technology and I have some live experiences about them.
If you are Indian, PHP is the best options for you to start. Not ASP.NET. Why?
Let me write down the reasons first. Next I’ll explain them in detail. I don’t claim, that this is final judgement and won’t suggest you to follow my reasons blindly. What I write, writing from a realistic point of view. You may agree or disagree. Whatever your opinion I’d like to get your comments.
Here are the reasons why PHP is better to start with.
1)Cost effective.
2)Open source.
3)Simplicity.
4)You don’t have to buy any software.
5)A good demand in small or medium company.
6)Takes less time to learn and start with.
7)Compactness and simple integrity with MySql database.(If you can conceptualize array, 50% job has been done!)

Now I’d like to clarify from my experience. One by one.

1) Cost : As a web developer, you’ll find that cost will play a very important role in the future. Whenever, you’d like to contact a hosting company they will always ask more money for a windows hosting which is needed for ASP.NET. For PHP you need Linux hosting that is almost half the amount for the same space and bandwidth. In Windows, it takes more cost because you need to hire an extra SQL Server. In PHP, MySql is in-built. So you need not spend extra dime for it. Form my experience I can say, in Linux hosting there are other advantages or features like blog, wiki, E-Commerce, image gallery projects like wordpress, phpbblog etc. In windows hosting you can not take advantage of such open source frameworks. What ever you want to do in ASP.NET, you have to do single handedly.
Some will argue here, there are many starter kits and open source projects available in ASP.NET also that you can download free from asp.net official site. Then where is the difference?
The difference is in installation process. In ASP.NET you may find some open source projects like blog, wiki etc. But to install them in a separate folder is quite cumbersome. On the contrary, WordPress or PHPBB type projects(run in php and MySql) are ready to install easily and quite user friendly.
So LAMP is not cheap in that sense but cost-effective.
2) Open Source
PHP/MySql is Open Source. If you want to learn more about it, please google it or read Wikipedia. You’ll get more idea about it. Basically it means, it is free, easy to use and there are much more free support from the community in every step. You can also edit the source code that you get from elsewhere.
3)Simplicity
ASP.NET is more user friendly, no doubt. But, if you want to learn the basic, core ideas on which the passage of data depends, then PHP is the best bet. If you can conceptualize array, then 50% job has been done.
4) You don’t have to buy any software.
To learn PHP/MySql you need not buy any software. This is free and that is why it is so much popular.
5)A good demand in small or medium company.
As the job market is concerned, small or medium level companies opt for free open source softwares. So PHP developers are in demand always.
6)Takes less time to learn and start with.
If you are from a computer background learning PHP is much easier. Logic plays a vital role. If you can follow the logic, how the logic flows, how data transfered from one page to other through array(name=>value) combination, the job has been done.
7)Compactness and simple integrity with MySql database.(If you can conceptualize array, 50% job has been done!)
The best friend of PHP is MySql. They are like Marx and Engels. You may type SQL in your PHP page and get the desired effect in your web page. Also, the hosting companies come with this great combinations so you start with an advantage.

A CMS without database

sanjibsinha — Wed, 26 Jan 2011 04:28:28 +0000

//I’d like to add, as “code” is not working here, it remains incomplete.
//In near future I’d like to complete it….

Probably PHP has more flexibility than any other web language. For instance, you need not declare data type. You name your variables according to your requirements and later use them.

PHP vastly based on array concept. Few Global arrays like $_POST, $_SERVER and $_FILE play a major role throughout the process of building an application. So far I learnt, I can assure, for small or even medium size application PHP is unparalleled.

Let us build a Simple Content Management System in PHP that will not take any help of database instead the content will be saved in a text file in a folder you mentioned.

Suppose you’d like to save your data in a folder called “cms”. So the path will be like this : cms/data.txt.

Let us start with a form that takes user inputs. The code is simple. Data passed through post method and we’ll catch them in a separate page.
First the form.

Adding Contents

Next add_data.php page where we add contents in a text file:
$id = 1;


if (file_exists("data.txt"))

{

	$fp = fopen("data.txt", 'r');

	$str = fread($fp, filesize("data.txt"));

	$str_arr = explode("|", $str);

	foreach ($str_arr as $rec)

	{

		if ($rec)

		{

			$id++;

		}

	}

}
$mode = (file_exists("data.txt"))? 'a' : 'w';

$fp = fopen("data.txt", $mode);

$str = $id . "--" . $_POST['uname'] ."--" . $_POST['txt'] . "|";
fwrite($fp, $str);

fclose($fp);

header("location: index.php");

As you see in the last line after you add data it redirects you to the index.php page. The code is:
$fp = fopen("data.txt", 'r'); $str = fread($fp, filesize("data.txt")); $str_arr = explode("|", $str);


echo "

";

echo "
";
foreach ($str_arr as $rec)

{

	if ($rec)

	{

		$rec_arr = explode("--", $rec);

		foreach ($rec_arr as $col)

		{

			echo "

";

			echo "
";

		}

		echo "
";

	}

}

echo "








$col
Edit


";

echo "Add data";

I’d like to edit and delete data on index page. But that part in the next blog. Till the next one happy coding!

Enjoying myself

PHP is running fine. From scratch I want to learn this language and I love the way it goes. I got a good teacher. I am fortunate. He teaches me logic which is very important in any programming language like PHP or C#(and also in Life).
I love Internet, no doubt – it is the most powerful tool, as whenever I wish I can see beautiful ladies I met before…
Life is interesting…

How to add codes?

PHP and Array

sanjibsinha — Sat, 08 Jan 2011 12:44:41 +0000

Array plays a vital role in PHP. I’m trying to understand the inner mechanism of it, specially while it takes values/data and processes it as array and keeping it as array?
Any way I’d like to make an array of beautiful eyes.
Today in the morning I had seen GD, she uploaded a new picture in her FB profile, where her great eyes are partially visible now. She should have done it before.
Okay, I’m happy with that.
Now again come back to PHP and array. I’d like to make an array of beautiful eyes. My wife Mithu will lead the array with GD following very closely.
Mithu has a brownish eyeball with a blue dot inside. GD has pure black eyes.
It looks like this:

$eye[0] = array(“Name”=>”Mithu”, “Eyes”=>”Beautiful”, “Relation”=>”Wife”, );
$eye[1] = array(“Name”=>”GD”, “Eyes”=>”Beautiful”, “Relation”=>”Fantasy”, );

ASP.NET and PHP, a basic difference

sanjibsinha — Tue, 04 Jan 2011 02:46:27 +0000

In ASP.NET you need to declare data type of variable explicitly. Like int num; that means num variable knows how much place it will hold in memory. It could be string str; float flt etc. But in PHP you need not do that. Usually you write $number to declare a integer variable.
So it is wise to pick up variable name so that it will mean either integer or string.
In PHP when you take up someone’s name you may write $name. It could be a string.
Actually what happens, PHP engine interprets the variable according to the value you are assigning it. That makes it operative part a little bit easier.
The CRUD concept is present in both. But, in ASP.NET it is more complicated and divided into many sections. Of course, people who know ASP.NET, may find it more organized too.
Lastly, due to windows, ASP.NET gives you a desk top experience and much more user friendly. If PHP gets something like this (I know nothing about zend framework although), it will be unstoppable and unparalleled due to its Open Source Presence.
Lastly, to host a ASP.NET site is more costly than PHP, and other Open Source helps make PHP much more desirable.
