Some interesting facts about PHP.

1) It is possible to use PHP in almost every operating system. PHP can be used in all major operating systems including Linux, Microsoft Windows, Mac OS X, and RISC OS.

2) PHP uses procedural programming or object oriented programming and also a mixture of them.

3) PHP is installed on over 20 million websites and 1 million web servers.

4) 75% of Web 2.0 sites are built in PHP.

5) There are about 5 million PHP developers worldwide.

6) The latest release of PHP till now is 5.3.0. It was released on Jun 30, 2009. PHP 6 is under development alongside PHP 5. Major changes include the removal of register_globals, magic quotes, and safe mode. The reason for the removals was that register_globals had given way to security holes, and magic quotes had an unpredictable nature, and was best avoided.

7) Some of the biggest online brands, such as Facebook, ProProfs, Digg, Friendster, Flickr, Technorati, and Yahoo! are powered by PHP.

What Every Developer Must Know About PHP 5.4 ?

Some of the key new features include traits, a shortened array syntax, a built-in webserver for testing purposes, use of $this in closures, class member access on instantiation, <?= is always available, and more!
PHP 5.4.0 significantly improves performance, memory footprint and fixes over 100 bugs. Notable deprecated/removed features include register_globals, magic_quotes (about time) and safe_mode. Also worth mentioning is the fact that multibyte support is enabled by default and default_charset has been changed from ISO-8859-1 to UTF-8.

1. Trait Support

As of PHP 5.4.0, PHP implements a method of code reuse called Traits.

Traits is a mechanism for code reuse in single inheritance languages such as PHP. A Trait is intended to reduce some limitations of single inheritance by enabling a developer to reuse sets of methods freely in several independent classes living in different class hierarchies. The semantics of the combination of Traits and classes is defined in a way which reduces complexity, and avoids the typical problems associated with multiple inheritance and Mixins.

A Trait is similar to a class, but only intended to group functionality in a fine-grained and consistent way. It is not possible to instantiate a Trait on its own. It is an addition to traditional inheritance and enables horizontal composition of behavior; that is, the application of class members without requiring inheritance.

2. Improvements to Arrays

PHP 5.4 includes two significant improvements to arrays – support for short array syntax and dereferencing of arrays from function and method calls. Both these changes make the code easier to read and manage.

No more temporary variables when dealing with arrays!
Let’s imagine that we want to retrieve the middle name of Alan Mathison Turing:

echo

explode(' ', 'Alan Mathison
  Turing')[1]; // Mathison

Sweet; but it wasn’t always this easy. Before 5.4, we had to do:

$tmp

= explode(' ', 'Alan Mathison
  Turing');

echo $tmp[1]; // Mathison

Now, what if we want to get the last name (last element in array):

echo

end(explode(' ', 'Alan Mathison
  Turing')); // Turing

This works fine, however, it will throw a E_STRICT (Strict Standards: Only variables should be passed by reference) error, since it became part of E_ALL in error_reporting.
Here’s a slightly more advanced example:

function foobar()

{

return ['foo' => ['bar' => 'Hello']];

}

echo foobar()['foo']['bar']; // Hello

3. $this Support in Closures

You can now refer to the object instance from anonymous functions (also known as closures) by using $this.

Anonymous or unnamed functions are called closures. These functions are very useful as the value of callback parameters. Prior to PHP 5.4, referring to object instances from closures required lengthy workarounds. With support for $this, you can call on any object property in any anonymous function, eliminating the need for hacks.

4. Built-in Web Server

Since the focus of PHP 5.4 is to streamline the development process, it includes a built-in web server in CLI mode on port 8000 to facilitate faster development and testing, thereby eliminating the need to set up an Apache HTTPD server. This server can be called on by using a simple command:

Open the command prompt (Windows + R, type in cmd, hit Enter); you should see something like this, depending on your Windows version.
Change your current directory to the PHP installation by following the example below:
Here comes the most important part – running the web-server. Copy…
… and paste it in the command prompt (right mouse button, click Paste to paste). Hit Enter. If all goes well, you should see something similar to what’s shown below. Do not close the command prompt; if you do, you will exit the web-server as well.

5. < ?= Support is Always Available

Regardless of the php.ini setting, short_open_tag, <?= (open PHP tag and echo) will always be available. This means that you can now safely use:

<?=$title?>…in your templates instead of…<?php echo $title ?>

How to create custom magento payment module - Part 4

app\design\frontend\default\default\etc\mycustom.xml

<?xml version="1.0"?>
<layout version="0.1.0">
<default>
</default>
< mycustom _index_index>
<reference name="content">
<block type="mycustom/ mycustom " name=" mycustom " template=" mycustom / mycustom .phtml" />
</reference>
</ mycustom _index_index>
</layout>

app\design\frontend\default\default\template\mycustom\form\mycustom.phtml

This is options to add your custom card number and expiry date in the payment methos step while you select your custom payment method.

<?php $_code=$this->getMethodCode() ?>
<ul class="form-list" id="payment_form_<?php echo $_code ?>" style="display:none;">
<li>
<label for="<?php echo $_code ?>_check_no" class="required"><em>*</em><?php echo $this->__('Mycustom Card Number:') ?></label>
<span class="input-box">
<input type="text" title="<?php echo $this->__('Check No#') ?>" class="input-text required-entry" id="<?php echo $_code ?>_check_no" name="payment[check_no]" value="<?php echo $this->htmlEscape($this->getInfoData('check_no')) ?>" />
</span>
</li>
<li>
<label for="<?php //echo $_code ?>_check_date" class="required"><em>*</em><?php echo $this->__('Expire At (format 2012-08-01 ):') ?></label>
<span class="input-box">
<input type="text" title="<?php echo $this->__('Check Date:') ?>" class="input-text required-entry" id="<?php echo $_code ?>_check_date" name="payment[check_date]" value="<?php echo $this->htmlEscape($this->getInfoData('check_date')) ?>" />
</span>
</li>
</ul>
<div>
<?php echo $this->getMethod()->getConfigData('message');?>
</div>

Finally when you select the custom payment in the checkout page and give the custom card number, expire date and click to submit the final step it will redirect your custom payment form.And fill the details and redirect to the site to finsih the payment successfully.

Implement and give your feedback's!!!!cheers!!!

How to create custom magento payment module - Part 1

Magento custom payment is very simple.If you have knowledge in magento its very simple to implement.
See the following steps to implement custom payment in magento.

Step 1:
Folder structure like this
app->etc->modules->Mycustomcard_Mycustom.xml

<?xml version="1.0"?>
<config>
    <modules>
        <Mycustomcard_Mycustom>
            <active>true</active>
            <codePool>local</codePool>
        </Mycustomcard_Mycustom>
    </modules>
</config>

Check this path in the back end.

System->configuration->Advanced->Disable Modules Output

In this page the "Mycustomcard_Mycustom" is make as enabled.

Step 2:
Then create folders like this.

app\code\local\Mycustomcard\Mycustom
app\code\local\Mycustomcard\Mycustom\Block\Form\Mycustom.php

class Mycustomcard_Mycustom_Block_Form_Mycustom extends Mage_Payment_Block_Form

Get location of an IP address

GET LOCATION OF AN IP ADDRESS

We can get the location (country name, country code, region name,city name) by using a simple json code below ... Enjoy it ... Thanks for jquery.com team.

<?php
$ip = "122.174.119.205";
$json = file_get_contents("http://www.codehelper.io/api/ips/?ip=".$ip."&full=true");
$json = json_decode($json,true);
echo "<pre>";
print_r($json );
?>
