Internationalization and Partial Rendering in the CodeIgniter Framework

As experienced Web developers, it won’t shock you to find literally thousands of comparisons between CodeIgniter and the other popular frameworks you may be considering for your site. Each framework has its good and, ummm… less good points, but

HTML Email Compatibility Across Mail Clients

Lots of compatibility issues occur when HTML developers deal with HTML-formatted emails generated using server side languages like PHP, PERL, JAVA, etc. in their projects.

From time to time you’ll find the odd gobbledygooked message in your Web-based email app, but generally speaking HTML-formatted messages render flawlessly on the Web.  On the other hand, desktop mail clients such as Outlook on Windows, Mail.app on OS X, and the rainbow flavors of desktop Linux (Ubuntu, Centos, and so on) routinely have rendering issues with HTML-based email.

Despite the incredible advances in modern software, why does this continue to happen?

The answer is quite simple: certain mail clients ignore certain HTML tags.  Now there’s no universal rule as to which ignores what, but the more you code the more you’ll learn, so for now let’s take a look at one case with Outlook.

For many users, email ‘stationery’ conjures up late 90s memories of Incredimail and a general, unsavory n00bishness.  But for marketing purposes a well-designed mail template, consisting of a stylish background image, thoughtful font selection, layout and copy equates to sales.  Perhaps thousands of people – from prospective clients to the media – will view mail…

Using the keyword "this" in PHP

You may come across number of functions, variables inside a class, you
call each one them as object of the class.

The keyword “this” is used in a class in php , to call and use these objects as
shown in the example below.

HTTP Request without CURL

A short tutorial on how to make a simple object for HTTP request without the need of using CURL.
The way to accomplish that is using the function stream_context_create to prepare the string, and then you use fopen and stream_get_contents to get the response.

<?php

class Custom_Http_Request
{
    private $_url;
    private $_body;
    private $_method = 'POST';
    private $_headers = array();
    private $_response;
    private $_stream;

    public function __construct($url, $body)
    {
        if (empty($url) || empty($body)) {
            throw new Exception('Both URL and BODY are required '
                              . 'for fetching the request.');
        }

        $this->_url  = $url;
        $this->_body = $body;
    }

    public function setMethod($method)
    {
        if ('POST' == $method || 'GET' == $method) {
            $this->_method = $method;
            return $this;
        }

        throw new Exception('Invalid method set.');
    }

    public function addHeader(array $header)
    {
        if (!empty($header)) {
            $this->_headers[] = $header;
            return $this;
        }

        throw new Exception('The headers are empty.');
    }

    public function getMethod()
    {
        return $this->_method;
    }

    public function getBody()
    {
        return $this->_body;
    }

    public function getHeaders()
    {
        return $this->_headers;
    }

    public function getResponse()
    {
        if (is_null($this->_stream)) {
            $this->_openStream();
        }

        if (is_null($this->_response)) {
            $this->_response = @stream_get_contents($this->_stream);

            if (false === $this->_response) {
                throw new Exception('It is not possible to '
                                  . 'read from the response.');
            }
        }
