PHP Tutorial (File Handling): Scratch Pad

09 Jan


Prerequisite

  1. Knowledge of basic PHP syntax.

In this tutorial you will learn about

  1. File Handling

Functions

We will be using 3 predefined functions for file handling

  1. fopen: To open a file
  2. file_get_content: To read a file
  3. fclose: To close a file

Little theory before we begin

Opening a file

Predefined function fopen() is used to open a file. It returns a variable which can be used for accessing the file. Returned variable is called as file handler.
Syntax:

$var = fopen("path to file", "mode");
 

mode: It controls how you want to access a file.
Note: It opens the file only if the logged-in user has permission to open it. If unable to open the file it returns false.

Google Sidewiki : Annotate anything or everything

25 Sep

google_logo_jan_09 Annotating web pages is not new. Over the years, numerous companies have  offered the services to do so. None of them actually left a mark, simply because it was too much a server load to handle. But Google with its huge resources and arrays of server, would be an interesting player. 

The idea is simple, to give users a place to share their views about the page that they just skimmed through and to add certain information if not present, next to any webpage.Google Sidewiki appears as a browser sidebar, where you can read and write entries along the side of the page.

SIDEWIKI Sidewiki has been launched as a special version of Google Toolbar for both IE and Mozilla. For other browsers its yet to be launched. When installed the toolbar opens a sidebar if any information about the web pages are available which have earlier been left by some other user. Google sorts out the best result in accordance with relevance. The sorting algorithm finds out information not just about the webpage we are going through but even according to the content of the web page. Lets say we have some famous quote from some famous personality. If someone comments on that particular quote it will show it as relevant result in any webpage it occurs.

The real catch is Google’s self designed method to sort out the most relevant result. It ranks Sidewiki entries using an algorithm that promotes the most useful and high quality entries. It takes into account the feedback from the users on the entries made by the author and some other signals. It then mines the data extracted from the these entries sing a scalable infrastructure called ‘Pregel’ ().

Till now the response has been good and is catching up fast. There has been some worries about the spam and entries showing non-relevant results. But overall if this things goes to full scale, combined with the information available on the webpage it simply can be a huge encyclopedia of knowledge and experience added. Moreover it will enhance the searching techniques. Google might just start Sidewiki discussions for particular search query or it can just include the relevant Sidewiki entries along with the forum or blog results available.

Another very important feature which Google has introduced along with this service is its API. All the Sidewiki comments and information will be available with the developers to be included in their applications and widgets.

Download Google toolbar from here.

 
 

Microsoft to release Security Essential soon…

22 Sep

Microsoft Security Essential Windows users have often complained about the lack of a proper security bundled with operating system. They are often caught up in dilemma when it comes to choosing an antivirus applications. Some of them are either too memory hogging or some lack punch. Microsoft earlier came up with a solution called ‘OneCare’ , which in spite of coming from the software giants was no match to the  leaders like Norton, Kaspersky… etc. It was just not enough. A little complex for naive home users and too simple for advanced ones. Moreover the detection rate took an year or so to catch up to a standard.

Yet again Microsoft has ventured into this territory and finally come out with something which definitely will scare the reigning giants. Microsoft Security Essentials, codenamed ‘Morro’, is to be a free security which for every genuine user of Windows operating system. Beta distribution of the software has come to an end and Microsoft has announced that it is going to release its security essentials in coming weeks. After the news of its release I decided to take a quick peek of what its going to be in future. I didn’t test it for viruses but concentrated mostly on the usability and interface of the software. For the virus test I referred to one the test conducted by AV-Test GmbH which highly rated this product. It stood against 3200 different viruses, malwares, Trojans, worms … etc with ease.

Microsoft Security Essential

The interface is extremely simple and meant for any user, even the first-timers. A few clicks and you get this beauty running. It updates itself automatically after install. The installer itself is just above 4mb but the problem is it download another 40mb to update itself before completely starts up. Once done it performs a quick scan of the system for the issues.  Though its not very customizable. The users who like to tweak with their system and the advance ones might just stick to their choices rather than switching over.

Quick Scan in Progress

Primarily built on core of ‘OneCare’ and can be said to be its stripped down, it the best when it comes to ease of usability. It has some simple options that one can customize. Unlike the complex interface of Norton Internet Security Suite or Kaspersky Internet Security Suite or any for that matter, it has a very less options to choose and very little knowledge required to use it. So all you need is internet connection and you are protected. Your don’t have to worry much about the regular pop ups and notifications. When this application is in effect you wont even know it is there.

There are some features that require a bit of know-how but surely this application serves for what it has been built for, security with ease.

There are a few lacks though. Windows firewall although is integrated with window and one might argue that it not required, but certainly it would have been a bonus if a well functioning and a bit more customizable firewall would have been attached to this application. Another issue some might find is that its not for professional purpose. It has been designed for basic home users with limited knowledge.

Settings of MSSE

Though it has a few but ignorable issues the biggest advantage it has over any other product is it being free. All you have to do is to buy a genuine Microsoft Operating System and you are protected from all the threats. This to be released security product is definitely going to change the way its going to be in future.Until now it has passed through most of the test we put it to, still the true test is the real world. But at this point we can say that Microsoft Security Essentials definitely has made its ground.

No more downloads are available from Microsoft, but you can download the product from other sources such as Softpedia.

Virus definition is also available as bulk download. click

 
 

Manage your Internet Bandwidth.!!!

20 Sep

With increasing number of ISP’s all over the world the number of users using high speed internet connection have risen tremendously. Almost all of the networks in developed nations are high speed. But for people like us who live in developing nation its still a distant dream. Though there has been developments, many of us now have the luxury of Broadband services yet there is a huge chunk of crowd still using over laden GPRS or dial up services. Everyone who has ever used these networks have craved for one and only one thing bandwidth; which indeed is scarce. Moreover whatever we have is also not used optimally. Much of the bandwidth we use, if not optimized, is wasted. When we are sitting in front of our terminals and hoping that the page we requested is opened, actually part of our data band is only used to serve us. This problem hurts most when we are a slow network user. Moreover if we are downloading a large file and want to check our mail we might have to wait forever to do so because the download might be eating all our bandwidth.

The best solution to this problem is to use some application to monitor and regulate the data bandwidth used by the applications present in system. One such application is NetLimiter. It can be categorized as client side traffic shaping and monitoring application. Certainly its job is not just the one mentioned above. It has many other roles to play not just being a distributer. NetLimiter comes as three different packages freeware, Lite and Pro. NetLimiter free is just a monitor and its job is to monitor the bandwidth consumed by various applications. Lite and Pro versions are advanced and can be used to shape the bandwidth allocated. The Pro version is accompanied with a firewall which works to expectations.

NetLimiter

NetLimiter Pro is way more than it looks. It has the ability to direct internet usage to multiple computers if put on a gateway. Unlike some other proxy applications it can regulate the inbound and outbound traffic in terms of bandwidth not in terms of connections per host. It has a permission editor by which one can allocate the resources required by the applications. Moreover it has the ability to control the traffic three different zones: Internet, My Computer and Local Network.
Broadband users have often complained about they exceeding the usage limit. This application keeps a record of the data transaction that took place on a day to day basis and can be used to keep a check on the data transmitted and received.

Individual Application allocation of Bandwidth

Another very important feature for professionals is the ability to administer the functioning of application remotely via their browsers.

Remote Management Of NetLimiter

The bad part of all this is its price is quite high considering its requirement. Though a recommended application, one should check on with their pockets.

Those looking for a freeware alternative will be disappointed as there is none. Though there are some alternatives such as cFosSpeed.

Cfos-Speed.

Opera Mini 5.0 Beta released…

20 Sep

Clipboard01With 30 million smiling faces, Opera delivers yet again. It unveiled its fifth generation of Opera Mini.

Facing stiff competition from Mozilla’s Fennec and the Skyfire recently , Opera did a fine job in putting up a rich featured and beautified marvel. Trying its best to meet the demands and expectations one can surely say that Opera has brought out its graphically enriched, attractive and much advanced browser.

Opera Mini 5.0 has has been imparted many features from its desktop counterpart  Opera 10. Unlike its predecessor it has Speed dial, a grid of nine thumbnail images, which is a replacement to Mini 4.2’s list of links. It has introduced a much demanded tabbed browsing interface. Though its not the first one to have this feature but surely the lightest one to do so. The fact that the browser like Fennec, Skyfire and even Opera Mobile are too heavy for some mobile phones, Mini 5.0 comes as boon with so many features. Plus the bonus being its Java platform which opens it endlessly for almost all platform.

Clipboard03

The glossy black interface has come with number of overhauls. Firstly the need of opening of a new window with every click onto an input field has been removed and one can directly type in the input boxes. The navigation menu has improved a lot from its previous versions.1

One of the most important feature of this browser is it being light weight. Unlike other browsers which i have used earlier performed poorly under low processing conditions. The tabbed features often led to an error ‘low in memory’. But it being light gives us very little trouble in this regards.

3

Another life saver from opera is the password manager. It does what is expected out of it and delivers its best. Apart from the ones mentioned above the whole action pack of Mini 4.2 is still available.

What’s missing?

Opera shook out some of its nagging features like skin and the ability to create a new search engine from any Web site. Another important feature which is missing is Opera Link ( Opera’s service for syncing bookmarks and Speed Dial between your various browsers, like desktop and mobile) . Though it is mentioned in one of its that its not there because the recent release is a Beta release.

Clipboard02

Still no hopes for video playback on Mini 5.0. Mini still lacks this ability as the flash plug-ins are disabled in the browser. You might be able to play videos from www.youtube.com but those don’t come directly from the standard youtube.com.

In spite of its drawbacks Opera Mini 5.0 packs enough punch to be acclaimed as a worthy upgrade to Mini 4.2.

You can download Opera Mini 5 beta for free from http://m.opera.com/next. Multiple versions are available for Black-berry and for other Java based mobile phones.

 
 

Tips: Reading download-only documents online Using simple google search

14 Aug

Sometimes while surfing the web, we ecounter some very necessary data in .docx OR .pdf format which cant be read without downloading.

Although there are many online document readers present online with tons of features, there is one by google which is very fast.
NO, I am not talking about Google Docs.

Its the google’s “view as HTML” feature which you find in simple google search.
Just copy and paste the document’s link in google’s search box and search for it. If google has already index the file it will show you a link to view the document as Simple Html page. Click on it and you can read all the text in the document.

This tips might not work everytime depending on google’s choice to index the file or not. But huh ! nothing bad in giving it a try instead of downloading the file.

On-mouse-over, the above code will change the background colour to black and text colour to white.
Similarely on-mouse-out it will change the background colour to white and text colour to black.

Adding/removing css class dynamically

You can use setAttribute javascript method to add a class to the calling object.

Code:

<style type="text/css">

background-color: #0099FF;
}
</style>

<input type="text" onmouseover="this.setAttribute(‘class’, ‘test’);this.setAttribute(‘className’, ‘test’);" onmouseout="this.setAttribute(‘class’, ”);this.setAttribute(‘className’, ”);"/>
