Websites that utilize databases which can insert content into a webpage by way of a dynamic script like PHP or JavaScript are increasingly popular. This type of site is considered dynamic. A dynamic URL is a page address that results from the search of a database-driven web site or the URL of a web site that runs a script.

e.g.  http://www.example.com/result.php?id=12345

Static URLs

URLs, in which the contents of the web page stay the same unless the changes are hard-coded into the HTML, dynamic URLs are generated from specific queries to a site’s database.

http://www.example.com/what-are-static-urls

Comparison:

1. Static URLs are typically ranked better in search engine results pages, and they are indexed more quickly than dynamic URLs

2. Static URLs are also easier for the end-user to view and understand what the page is about.

3. If a user sees a URL in a search engine query that matches the title and description, they are more likely to click on that URL than one that doesn’t make sense to them.

Problems with Dynamic URL:

1. A search engine wants to only list pages its index that are unique. Search engines decide to combat this issue by cutting off the URLs after a specific number of variable strings (e.g.: ? & =).

For example, let’s look at three URLs:

http://www.example.com/result.php?id=12345

http://www.example.com/result.php?id=12346

http://www.example.com/result.php?id=12347

All three of these URLs point to three different pages. But if the search engine purges the information after the first offending character, the question mark (?), now all three pages look the same:

http://www.example.com/result.php

http://www.example.com/result.php

http://www.example.com/result.php

Now, you don’t have unique pages, and consequently, the duplicate URLs won’t be indexed.

2. Dynamic pages generally do not have any keywords in the URL. Highly relevant keywords should appear in the domain name or the page URL. This became clear in a recent study on how the top three search engines, Google, Yahoo, and MSN, rank websites.

The study involved taking hundreds of highly competitive keyword queries, like travel, cars, and computer software, and comparing factors involving the top ten results. The statistics show that of those top ten, Google has 40-50% of those with the keyword either in the URL or the domain; Yahoo shows 60%; and MSN has an astonishing 85%! What that means is that to these search engines, having your keywords in your URL or domain name could mean the difference between a top ten ranking, and a ranking far down in the results pages.

Like : <a href=”http://www.example.com/filename.doc”>Download Document</a>

It should be something hidden. In order to resolve this case, I came up with the following suggestions:

• Instead of passing the direct filename pass the id of the file (give file a id) e.g 1234
• Pass the File Id to a certain piece of code which keeps the track of download and pushes the file for download

Lets Start over to make this concept a reality:

Now when a user click over the link a script is run which calls the script.php code and passes a code parameter with the id 1234.

Script File Code:

• <?php
• //Gets the file code $filecode = $_GET['code'];
• //Write here the code to get the real name of the file from the database and update the counter for that file
• //Let suppose the filename is 1234.doc
• $file = ‘downloadfile/’.$filename;
• //Rest of the code helps to push the file for download to the user
• header(‘Content-type: application/force-download’);
• header(‘Content-Transfer-Encoding: Binary’);
• header(‘Content-disposition: attachment;
• filename=”‘. basename($file) .’”‘);
• header(‘Content-length: ‘. filesize($file) );
• readfile( $file );
• ?>

You can go ahead and try out the concept, if you have any certain query post a comment out for the help.

2. Every browser views differently
I call this as the pain of my life. Every browsers has its own setting as well as every computer isnt configured the same. Be mindfull of this, what you are looking at on your end might not be the same as other users. Always test your site out on several computers before launching. The best tool to use for this purpose is Adobe Browser Test.

3. Page recognition
Spell out for the viewer very easily what the point of your page is. Browsers should be able to understand the intention of why the page was created within a few seconds of entering the page.

4. Slow loading pages
Keep your pages loading quick so you do not drive away potential clients. Flash players tend to bog down your sites so keep them as lite as possible.

If you have more of these kinds, kindly share using your comments.

They don’t have any essential part of a website but can provide some of the “little things” that can set your website apart from the rest. Cookies are small tidbits of information that you save on the client’s computer so that you can access them next time they visit the website.

Purpose of Using Cookies:

• Store Username and Password for future access (i.e. The “Remember Me” Check mark that you normally see on the sites
• Use for keeping track of the users progress (i.e. Check whether the person have already performed a certain action on the website)

How to use Cookies?
Well we will be using php for this purpose to demonstrate it.
1. Setting the Cookies: Setting a cookie requires a key, a value, and the amount of time to allow the cookie to exist.

$value = 'Some Value Here';
setcookie('name',$value, time()+60*60*24*30); //  time()+60*60*24*30 = 30 days

2. Getting the Values of the Cookies: Getting the value of the cookies are very simply, you can easily get them by using the variable name defined.

if(isset($_COOKIE['name']) && $_COOKIE['name']!='')
{
  echo $_COOKIE['name'];
}

They can even be set to specific directories directives, including path, domain using the following piece of code.

setcookie('name',$value,time() + time()+60*60*24*30,'/~foldername/','domain.name',true,true);

This cookie is the same as the code mentioned before, but we’re telling the cookie to be applied towards the directoryname : “~foldername” on the domain : “domain.name”. It is for use only on an SSL connection and it may not be used by JavaScript.

Few things to remember:

• A user can delete cookies at any time.
• A user can turn cookies off in their browser.

Hope this small piece of reference information may help you.

if in-case of any queries regarding this you can always contact me using the comment section.

Step 1 : Login to Facebook to Create a Facebook Application

First login to Facebook and goto the url http://www.facebook.com/developers/ then Click on “+ Set Up New Application” button to start creating the application as shown below.

Provide the application name, click agree for facebook terms and click on “Create Application” button.

Once the Application is created. Just copy the Application API Key, Application Secret and Application ID details which will be used to write the application code.

Provide the Name and Description of your application in About Section.

Step 2 : Download the Facebook PHP Library

In order to download the latest PHP Libarary, use the following URL : https://github.com/facebook/php-sdk/

Step 3 : Generate one time session key (permanent session key) and Showing how Connect Works

'secret' => '943716006e74d9b9283d4d5d8ab93204',
'cookie' => true,
));
$session = $facebook->getSession();
$me = null;
// Session based API call.
if ($session) {
try {
$uid = $facebook->getUser();
$me = $facebook->api('/me');
} catch (FacebookApiException $e) {
error_log($e);
}
}
// login or logout url will be needed depending on current user state.
if ($me) {
$logoutUrl = $facebook->getLogoutUrl();
} else {
$loginUrl = $facebook->getLoginUrl();
}
// This call will always work since we are fetching public data.
$naitik = $facebook->api('/naitik');
?>

Naitik

1. // generate unique string
2. echo md5(time() . mt_rand(1,1000000));

There is actually a PHP function named uniqid() that is meant to be used for this.

Since the function is dependent upon the time, the initial few characters could be similar. Because of which one may think there could be a chance of duplicating the Ids. In order to resolve this simply add 1 more parameter to it and this becomes unique.

It aims to make the web more accessible and adaptable.
