Upcoming changes in PHP 6.0

PHP 6.0 looks to be an exciting release. Nothing is absolutely fixed yet, but it looks like it will see the demise of three of my pet peeves: register_globals, magic_quotes_gpc and safe_mode. The first was just a big security hole, the second messed with the data and made changing environments potentially nightmarish, while the third was a misnomer that nobody really understood, and provided a false sense of security. There's also quite a lot of work scheduled to do with Unicode. Here are some of the changes:

The register_globals, safe_mode and the various magic quotes options will be removed.
The ereg extension is removed, while the XMLReader, XMLWriter and Fileinfo extensions are added to the core, and by default are on.
Another addition I find particularly exciting is that APC (Alternative PHP Cache) will be added to the core, though will be off by default. APC can provide serious performance benefits.
All E_STRICT messages will be merged into E_ALL, another positive change that will encourage good programming practice.
ASP style <% tags will no longer be supported.
Addition of a new 64-bit integers. The current integer type remains as is, 32 or 64-bit dependent on the platform.
Use of foreach with multi-dimensional arrays, for example foreach($array as $k => list($a, $b)).
A new switch in php.ini will allow you to disable Unicode semantics (by default they will be on).
There will also be various string improvements related to Unicode.
The microtime() function will return the full floating point number, rather than microseconds unix_timestamp, as at present, probably making the function more readily useful for most people.
The {} notation for string indexes will no longer be supported, while the [] version will get added substr() and array_slice() functionality. Previously [] was deprecated, but most developers, including myself, seem to use [].
FastCGI will always be enabled for the CGI SAPI, and will not be able to be disabled.
The ancient HTTP_*_VARS globals will no longer be supported. Everyone should have had more than enough time to remove any traces of these.
var will alias public. var was permitted with PHP4 classes, but in PHP 5 this raised a warning. In PHP 6 var will simply be an alias for public, so no warning is necessary.
The ze1 compatibility mode, which tried to retain PHP 4 behaviour but had some bugs, will be removed.
Dynamic functions will no longer be permitted to be called with static syntax.

There's still much to be determined, namespaces being one of the more important, but as yet there's little agreement. You can read the full minutes from the recent PHP Developer's meeting here where PHP 6 was discussed at length. With PHP 6 still quite a way off, I'm sure there'll be much more wailing and gnashing of teeth before we see the final product, but I'm excited by where it seems to be heading, and the progress that is being made.

Interface in Php

An Interface is like a template similar to abstract class
with a difference where it uses only abstract methods.

In simple words, an interface is like a class using
interface keyword and contains only function
declarations(function with no body).

An Interface should be implemented in the class and all the
methods or functions should be overwridden in this class.

for eg:

interface InterfaceName{
 function fun1();
 function fun2(a,b);   
}

class ClassName implements InterfaceName{
 fuction fun1(){
   function implementation.......
 }
 fuction fun2(a,b){
   function implementation.......
 }
}

Removing index.php from the url in codeigniter

Hi,

I also tried to find out many the exact way to remove the index.php from the url but did not get much help. Then after lots of hits and try I made the .htacess that is working for me. So I wanted to share this with you all.
My framework is in the folder abc.

The .htaccess

RewriteEngine on
RewriteCond %{QUERY_STRING} ^(ACT=.*)$ [NC]
RewriteRule ^(.*)$ index.php?%1 [L]
RewriteCond $1 !^(images|_css|_js|scripts|cal|uploads|portal_member_image|index.php) [NC]
RewriteRule ^(.*) /abc/index.php?/$1 [L]

And when ever you make a call to a controller please specify the full url without the index.php like if I want to call a controller called hi controller and inside that a hello function then what i will have to write is.

redirect($this->config->item('baseurl').'hi/hello');

Hope this will of any help to someone.

Thanks
Jawed

Pagination in codeigniter

I've often see forum posts asking why the Pagination class isn't working. I decided to create a tutorial on the Pagination class for those who need to learn about the pagination class.

Let's now start with the pagination tutorial. This tutorial assumes that you have connected your CodeIgniter application to the database.

First, we need to create a table.

CREATE TABLE IF NOT EXISTS `articles` (
 `id` int(11) NOT NULL auto_increment,
 `title` varchar(50) NOT NULL,
 `content` text NOT NULL,
 PRIMARY KEY  (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;

Next, we create our own Model for our articles table.


class Articles_model extends Model {

function Articles_model()
{
 parent::Model();
}

function get_posts($limit = NULL, $offset = NULL)
{
 $this->db->limit($limit, $offset);
 return $this->db->get('posts');
}

function count_posts()
{
 return $this->db->count_all_results('posts');
}

The method Articles_model() is the constructor. In PHP 4, constructors are named after the class they are located in.

The method get_posts(), retrieves the information from the database. Notice that it has parameters for limiting and the offset of returned rows.

The method count_posts(), retrieves the total number of posts available in the table.

Next on our list is creating the controller function.


class Posts extends Controller {

function Posts()
{
 parent::Controller();
}

function manage()
{
  $this->load->model('posts_model');
  $per_page = 10;
  $total = $this->posts_model->count_posts();
  $data['posts'] = $this->posts_model->get_posts($per_page, $this->uri->segment(3));

  $base_url = site_url('posts/manage');
  $config['base_url'] = $base_url;
  $config['total_rows'] = $total;
  $config['per_page'] = $per_page;
  $config['uri_segment'] = '3';

  $this->pagination->initialize($config);
  $this->load->view('admin/posts/manage', $data);
}

Copy and paste and do not worry if you don't understand that chunk of code yet. We will get back to that later on.

Making site in some other language like hebrew

I’ve been working on a little application that grabs data from Hebrew news sites into a mySQL database.

While working on this mini-project I’ve realized that there is hardly any online tutorials on using the Hebrew font. Here’s my solution which is fairly simple and works effectively.

Step 1) Set the HTML page charset encoding to utf8:

meta http-equiv=”Content-Type” content=”text/html; charset=UTF-8“

Step 2) set the ‘collation’ attribute for the fields which are to accept hebrew text to: utf8_bin

Step 3) within your php script, right before calling the mysql_query function to insert the data into your DB, use both the utf8_encode function along with addslashes. This will encode the data into utf8 friendly characters.

Step 4) when pulling the text from the DB onto the page, make sure to use the utf8_decode along with stripslashes in order to display the data on the page.

useful url rewriting examples using .htaccess

1)Rewriting product.php?id=12 to product-12.html
It is a simple redirection in which .php extension is hidden from the browser’s address bar and dynamic url (containing “?” character) is converted into a static URL.
RewriteEngine on
RewriteRule ^product-([0-9]+)\.html$ product.php?id=$1
2) Rewriting product.php?id=12 to product/ipod-nano/12.html
SEO expert always suggest to display the main keyword in the URL. In the following URL rewriting technique you can display the name of the product in URL.
RewriteEngine on
RewriteRule ^product/([a-zA-Z0-9_-]+)/([0-9]+)\.html

$ product.php?id=$2
3) Rewriting yoursite.com/user.php?username=xyz to yoursite.com/xyz
Have you checked zorpia.com.If you type http://zorpia.com/roshanbh233 in browser you can see my profile over there. If you want to do the same kind of redirection i.e http://yoursite.com/xyz to http://yoursite.com/user.php?username=xyz then you can add the following code to the .htaccess file.
RewriteEngine On
RewriteRule ^([a-zA-Z0-9_-]+)$ user.php?username=$1
RewriteRule ^([a-zA-Z0-9_-]+)/$ user.php?username=$1
4) Redirecting the domain to a new subfolder of inside public_html.
Suppose the you’ve redeveloped your site and all the new development reside inside the “new” folder of inside root folder.Then the new development of the website can be accessed like “test.com/new”. Now moving these files to the root folder can be a hectic process so you can create the following code inside the .htaccess file and place it under the root folder of the website. In result, www.test.com point out to the files inside “new” folder.
RewriteEngine On
RewriteCond %{HTTP_HOST} ^test\.com$ [OR]
RewriteCond %{HTTP_HOST} ^www\.test\.com$
RewriteCond %{REQUEST_URI} !^/new/
RewriteRule (.*) /new/$1
