I will show how to install Zend Application Framework on Ubuntu. I hope you have already installed php, apache in you Ubuntu box.

1. Download the latest version of Zend Framework from the zend  site
2. Save the Framework source on your www directory and extract it. I have extracted it in /var/www/ directory

         3.Now set the suitable permission to the directory. So type in the following commands to Shell

4. Now enable the Zend framework tool or the zf tool. zf is a command line tool to create project and perform others operation for zend application. To enable the zf tool, we have to create a symlink to the tool. Copy and run the command to your shell

This will create a symlink to /usr/bin/

5. Next we will enable the Library path to the php.ini. So to do that we will open the file in a vim editor. So for that we will again go to the terminal and type the following,As we are using Ubuntu so php.ini will be in “/etc/php5/apache2/”.

I am using vim editor here to edit the php.ini file, you can use whatever tool you like

There search for include_path. You will see an area that says,

;include_path = “.:/usr/share/php”;

include_path = “.:/usr/share/php :/var/www/ZendFramework-1.11.12/library”

Uncomment the include_path line and add your Zend Framework library path. Save the file and exit.

6. Restart the apache with bellow command in shell

7. Now we are ready to create project. In the shell run the bellow command

This command will create a project in /var/www/ directory with a name zend_learn

8. Now open your browser and type http://localhost/zend_learn/public/

You should see the bellow output in the browser

You are ready to code in Zend Framework

Bellow I will show how to use SHA256 encryption method to create secure password hash.

We just need  two simple function:

First function genenrate_salt create a random string which will be used as salt for password hashing and function genenrate_password   do the rest

<?php

function genenrate_salt(){
$rndstring = "";
$length = 64;
$a = "";
$b = "";
$template = "1234567890abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ";
settype($length, "integer");
settype($rndstring, "string");
settype($a, "integer");
settype($b, "integer");

for ($a = 0; $a <= $length; $a++) {
$b = rand(0, strlen($template) - 1);
$rndstring .= $template[$b];
}

return $rndstring;
}

function genenrate_password($salt,$pass){
$password_hash = '';

$mysalt = $salt;
$password_hash= hash('SHA256', "-".$mysalt."-".$pass."-");

return $password_hash;
}

$salt = genenrate_salt();
$plain_pass = "hello123"; /* any password/text collected from user input */

echo "My Hash Password Is: ".genenrate_password($salt , $plain_pass);

?

Hope this will help some one.

<?php

function get_age($birth_date){
 return floor((time() - strtotime($birth_date))/31556926);
 }

echo " I am ".get_age("2000-05-10") ." years old";

?>

Output: I am  12 years old

1. The document Type(Doctype) Declaration:

The HTML <!DOCTYPE> is used  to  specify  which version and language the document is using.

Before (Xhtml):

After (html5):

It will work in older browsers too. This is not only for html5, it’s also for earlier version of html.

2.    Meta Charset:

Before (Xhtml):

After:

3.    Scripts and Links:

Before (Xhtml):

<script type="text/javascript" src="script.js"></script>

After (html5):

</pre>

<script type="text/javascript" src="script.js"></script>

Here the type attribute is removed

4.    Form  Input Type:

<input id="email" type="email" name="email" />                 <!-- email  type for select email with validation -->
<input type="color" name="txtcolor" />                          <!--color type for select color -->
<input type="tel" name="usrtel" />                             <!-- tel field is  for telephone number -->
<input type="date" name="bday" />                                 <!--date type for select date-->
<input type="datetime" name="txtdatetime" />                     <!--datetime type for select date-->
<input type="month" name="txtmonth" />                         <!-- month type for select month-->
<input type="number" name="quantity" />        <!--quantity  type for  numeric field-->
<input type="search" name="googlesearch" />                  <!-- search type for search-->

5. Placeholder:

<input type="text" name="search" />

Use placeholder attribute. you don’t need JavaScript  for this event.

More Command

CodeIgniter can be used from small web site to large scale complex web application. With CodeIgniter, you can save time, make your web application more robust, your code will be easier to read and maintenance. It is free, lightweight, and simple to install.

CodeIgniter is a MVC (Mode, view and controller) framework and from the bellow diagram you can get an overview of MVC.

In MVC you can logically segregate different part of an application.


In a simple line we can explain the MVC: View contains the presentation layer (user interface or html), Controller decides the flow of control for the application and Model deals with data and business logic.

Next part I will show the CodeIgniter  installation and configuraiton

Follow the bellow steps:
1. create a php file with name MY_Router.php and put in inside application/libraries directory
2. put the bellow code into the file

<?php
Class MY_Router extends CI_Router
{
Function MY_Router()
{
parent::CI_Router();
}

function _validate_request($segments)
{
if (file_exists(APPPATH.'controllers/'.$segments[0].EXT))
{
return $segments;
}

if (is_dir(APPPATH.'controllers/'.$segments[0]))
{
$this->set_directory($segments[0]);
$segments = array_slice($segments, 1);

while(count($segments) > 0 && is_dir(APPPATH.'controllers/'.$this->directory.$segments[0]))
{

$this->set_directory($this->directory . $segments[0]);
$segments = array_slice($segments, 1);
}

if (count($segments) > 0)
{
if ( ! file_exists(APPPATH.'controllers/'.$this->fetch_directory().$segments[0].EXT))
{
show_404($this->fetch_directory().$segments[0]); /* show 404 page */
}
}
else
{
$this->set_class($this->default_controller);
$this->set_method('index');

if ( ! file_exists(APPPATH.'controllers/'.$this->fetch_directory().$this->default_controller.EXT))
{
$this->directory = '';
return array();
}

}

return $segments;
}

}
}
?>

3. now you can access the controller like this http://localhost/CodeIgniter_1.7.2/admin/section/welcome
here admin/section is Sub Folder and welcome is the controller name

Hope this will  help some one………

Note: This fix will work only CodeIgniter version upto  1.7.3

Codeigniter is one of the most popular PHP  framework. By default it shows index.php page in the url.
By default it will show the url like  http://localhost/my-application-name/index.php/news/hello
I will show very easy way to remove the index.php from the url.

You just need 2 step

1.  Create an .htaccess file into the root dir and put the bellow lines of command

RewriteEngine On
RewriteBase /my-application-name

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php?/$1 [L]

In  RewriteBase you need to give your application name. Here I have given name my-application-name. You will need to change this name according you application name.

2. Go to application/config directory. Open config.php file.
Change $config['index_page'] = “index.php”;  to $config['index_page'] = “”;

and you are done. Now you can visit your site like this
http://localhost/my-application-name/news/hello

Note:  You must have mod_rewrite module enabled for apache
