Api for XML

There are various api for accessing xml documents. They are the following-

  • Stream oriented api: Simple api for xml or SAX, it is event based.
  • Tree traversal api: Dom is a tree-traversal api. DOM implementation is memory intensive, as it loads the whole xml tree before accessing data.
  • Xml data binding: which is a automated way to convert XML document.
  • Declarative transformation languages: XSLT, XQuery.

Introduction to JSON

JSON means javascript object notation. JSON is lightweight and very easy to parse.
It is not a markup language. The basis of JSON is that javascript’s object literal
is the ideal way for transmitting object oriented data across the network. Json made it easier to produce distributed object and applications. JSON does not support octal or hex characters. The character encoding of json is always Unicode. Json is the preferred way for ajax applications. A response text can be converted to javascript with eval() function. json's values can be used directly, no convertiion needed. this is the most significant reason to use json. json has no namespaces so there is no nesting and it uses context. JSON doesn't have any validator.

Why should I use static variable?

Let’s see the difference between static and non-static variable:
Static is used for those method and variables which are accessed from other classes or functions also. If we use non-static, then we need to instantiate the class each time to use that methods or variables. Static variable has it’s scope until the script ends, whereas a non-static variable lost it’s value when it’s scope ends.

OOP vs procedural

OOP provides ways for extensible application. this approach removes the drawbacks of procedural paradigm. it gives first priority to data. it packs data and functions, which have access to this functions. this avoids unauthorized access to functions. So, OOP gives us ability of reuse, inheritence, access modifier.

procedural provides ways for fast, shortcut approach for programming. so, before coding we must think what we want to do. if we want a small coding to do a small job, then we must go for procedural approach. But as the requirements grew, it was seen that the programs were getting larger and larger and it became difficult to debug. So functions were introduced to reduce the size of the programs and improve readability in them. Still that was not enough. In this approach, data is getting corrupted, as many functions which are not allowed to access the function can access the functions. so, here more focus was given on functions, rather than data.

Problem with normal and session variable having same name

If your register_globals is set to ON, then a normal variable will overwrite a session variable with the same name. In webid, I faced this problem. It's not a good practice to turn ON register_globals. So, turn it Off it will fix the problem with same variable name.

xml vs database

XML can be used as databases. But the question is that why should I use it or why should I avoid it? XML has the properties of storage, portability, schemas. Xml is self describing means the elements, attributes tells what the data it contains. It also describes data in tree or graph structure.
Xml provides many qualities of databases.
1. Storage: Xml documents.
2. Schemas: DTDs, Xml schemas.
3. Query languages: Xpath, Xquery.
4. Programming interfaces: SAX, DOM.
And it also lacks some of the cool features of databases.
1. Security.
2. Integrity.
3. Indexes.
4. Transaction.
5. Efficient storage.
6. Multi user access.
7. Triggers.
8. Queries across multiple documents.
So, xml can be used as a database for few users, small amount of data. But for product environment where there will larger data, huge user, need data integrity, there needs databases. So, there is very little advantage to use xml as a database.

.htaccess intro

.htaccess files are used to modify server configuration on per-directory basis. It is used when a user doesn’t has access to modify server configuration settings. The directives in .htaccess file is applied for the current directory and subdirectories. .htaccess uses those directives that has their AllowOverride property set to not none.

If we can, we should avoid using .htaccess file mainly for the following 2 reasons –
1. When we set AllowOverride property to allow modification in .htaccess files, then the server checks every directory for .htaccess file. This hit the performance.
2. Second one is security. We are allowing users to change server configuration. So, it may become a security hole.

Use component as multipart document

This will use different component of a webpage as an attachment. So, components will be loaded with one http request. This will improve webpage loading time. But iphone doesn’t support this technique.

minify js and css

We can minify javascript and css, so the loading of these files will be faster. There are two popular tools: jsmin and YUI compression. YUI compression can compress CSS files also. Minify will reduce size upto 25% of it size. We can use minify after gzip, it will reduce the size upto 5%. Minify removes redundant contents.

Reduce DNS lookups

Each DNS will be converted to IP address. Server will wait until the conversion completes. DNS lookup takes 20-100 miliseconds. The DNS is cached for later use. Firefox uses 1 min, IE uses 30 min for the dns caching. This caching is done on a special caching server. Each browser has a own DNS cache. It also stores the information on the operating systems cache.
Reducing DNS lookup cuts response time, but also reduces parallel downloading so increases response time. We can use upto 4 hostnames which will increase our speed.

Use external files for javascript and css

Using external files for javascript and css will reduce the file size without increasing the number of http requests. But we can use inline code for home page which has less page views. So, we can use caching for those pages which reuses same scripts and stylesheets.

There are some files which are common on homepage and other pages. For that case, we can load inline codes for homepage and then we can load those scripts by external files.

CSS expressions

CSS expressions use javascripts. And the page is evaluated for scrolling or even mouse moving. We avoid expressions as they create many evaluation to the page. So, if we need to use expressions we must use one-time loading.

Put scripts at the bottom

According to the http/1.1 a page can download no more than 2 scripts at a time. While a script is downloading, however, the browser won't start any other downloads, even on different hostnames.

Sometime, we can’t put scripts at the bottom. When the scripts load some content that will be used in the middle of the page, then we need to call the script early. We can use DEFER attribute which shows the script does not contain document.write. but firefox doesn’t support this attribute.

Loading stylesheets on top

Always include stylesheets in the head tag. This will load the page faster. Users want to see their pages faster. So, for this purposes, the loading image is getting popular. So, if we set the stylesheets in the head tag, then the images, banner, header will load faster and will give the user an impression of page loading. If we place the stylesheet at the bottom, then it may show a blank page for some time in some browser like internet explorer.

Gzip contents

Web content size can be reduced by gziping them. If we set accept-encoding to gzip or any other compression techniques, then the web server responses with the content-encoding header that tells the browser to compress the web content.
We can’t compress images and pdf files as they are already compressed. By compressing these may increase web content size.

Cache control

For caching features, we can use two techniques-
1. For static contents, we can set the expire attribute to a furthest future.
2. For dynamic contents, we can set an appropriate cache-control.
For static contents, like images, stylesheet, flash etc, can be cached in the browser for faster page load. This will reduce http request time. This will not effect for the first time the page loads, but the result will be at later page requests when the cache will be full.

Using content delivery network

Content delivery network(CDN) is a distributed service of static contents i.e. images, stylesheets, javascripts, flash etc. it will reduce http loading time drastically. There are many organization who provides this service. CDN uses many distributed servers who will store the static contents. In this case, the nearest or the shortest response time server is chosen.

Reducing HTTP request

To speed up a web page loading, our first goal will be to reduce the number of http request. The less the http request, the faster the page will be load. There are many ways to reduce http request. We can use css sprites, combined css, image maps etc. there is another technique called inline images, it uses of the form, data: mediatype;base64;data.Another way to reduce the number of http request is by having a full cache.

Minify your javascript file with jsmin

It will minify the javascript file. We minify javascript files so it will reduce page loading. JSMin first replaces carriage returns ('\r') with linefeeds ('\n'). It replaces all other control characters (including tab) with spaces. It replaces comments in the // form with linefeeds. It replaces comments in the /* */ form with spaces. There are many supported programming language available to use jsmin. I used php.

Affiliate program in prestashop

Prestashop 1.2 comes with a affiliate module. By this we can track affiliates. You need to set every thing manually here.
To start with affiliate program, go to the back office > stats > referrers. To add a new affiliates, click the add new button.
You need to create an affiliate account first with username and password. Under that section there is the url by which you can see the affiliate space on the front office.
With the HTTP_REFERER section, set the domain name in the include field that you want to track as your affiliate domain. We can use the keyword like ‘MySQL LIKE’ feature, for example, put ‘%google%’, this will track all the request that come from the google search engine.
With the Request_uri section, we can set the last part of the query string. Our affiliate program will track this url. For example, someone uses %aff% in the include field. So, his affiliate link will be any url of the shop that have ‘aff’ in it’s url.
Then save your changes. You can see your affiliate statistics in the front panel. It will take approximately an hour to see the changes.

how to write a module with prestashop

Every module is load with a hook. A hook is a module holder. Prestashop has some default hooks. We will see later how to createhooks.

Ok, now lets start to make a module with prestashop. First make a folder with the modulename. Create a .tpl file with the modulename. Write the presentation code here.
Then create a .php file with the modulename. The following is a dummy class for our module.


// class name must be same with the modulename, not case sensitive.

class Fashion extends Module
{
function __construct()
{
$this->name = 'fashion'; // this is the name of the module
$this->tab = 'Blocks';
$this->version = 1.0;

parent::__construct(); // The parent construct is required for translations

$this->page = basename(__FILE__, '.php');
$this->displayName = $this->l('Block Fashion');
$this->description = $this->l('Add a fashion block');
}

function install()
{
if (!parent::install())
return false;
if (!$this->registerHook('leftColumn')) // we are setting this module with the left column.
return false;
return true;
}

/**
* Returns module content
*
* @param array $params Parameters
* @return string Content
*/
// as we are setting this module on left column, we are using this hook to load our module.
function hookLeftColumn($params)
{
return $this->display(__FILE__, 'fashion.tpl');
}

}
?>

Changing position of a module in prestashop

Prestashop is module based. It uses hooks to load the module. Not every hook can load every module.

To change the position of a module, go to the admin. Then module>positions. You can change position of the modules by clicking the edit button next to every module or you can click the transplant button. In the transplantation form, from the first list, we can choose the module that we want to move and from the second list, we will find the location where we will show the module. The third field accepts file names that will not show the module. These file’s path will be set from the base directory.
